Investigation of the hybridization effect on mechanical properties of natural fiber reinforced biosourced composites

Hybridizing the natural fibers with stronger synthetic fibers could significantly improve the properties of the natural fiber-reinforced composites. The improved mechanical capabilities of fiber reinforced polymers result from the fiber’s capacity for withstanding a more substantial portion of the mechanical load compared to the matrix it replaces. In order to guarantee the efficient transfer of the mechanical load from the matrix to the reinforcement, it is necessary to incorporate a fibrous filler. Transference takes place when the length of the fiber is longer than a specific critical length. Fibers which are shorter than the critical length will pull out from the matrix when tested to a tensile load. In some cases, complete transfer of the load is not performed. The goal of this study is to learn more about flax (FF), glass (GF), and mixtures of flax and glass (FF + GF) short fiber-reinforced PLA-PBS composites. This is performed to find out how the flax/glass combination affects the mechanical properties of PLA-PBS-reinforced short fiber composites. In order to extend their use for industrial applications, these composites were manufactured via extrusion and, afterward, injection molding. Fiber aspect ratios were followed after compounding and injection processing. The analysis of fiber lengths reveals a noteworthy observation: the proportion of fibers exceeding their critical length of 531 µm and 772 µm for FF and GF, respectively, is more significant when flax fibers (FF) and glass fibers (GF) are combined compared to when they reinforce the composite individually. Specifically, the composite containing both FF and GF exhibits a higher percentage of fibers surpassing their critical length, compared to their individual reinforcement in the composite. The results reveal that 27% of individually extracted single FF exceed their critical length, whereas a higher proportion, at 34%, is observed when FF is part of the composite mixture. In contrast, the critical length is surpassed by only 4% of individually extracted single GF, whereas the combined presence of GF in the composite results in a notably higher percentage, at 19%. The tensile properties of these composites were investigated considering the effect of the hybridization by flax/glass short fibers. It was noted that the tensile properties of the hybrid composites increase comparing to the flax composites from 42.4 MPa to 53 MPa for the tensile strength and from 4.9 GPa to 5.4 GPa for the tensile modulus. In contrast, the elongation at break of the hybrid composites decreases from 1.7% to 1.5% with the incorporation of glass fibers. The experimental results were compared with the predictions of the mixture law and the Cox-Krenchel model. The findings indicate that mixing synthetic fibers with natural fibers is an excellent approach to enhancing mechanical properties.

Effect of temperature on the uniaxial tensile properties of wood plastic composites: Experimental investigation and numerical analysis

Seven groups of uniaxial tensile experiments on wood plastic composites with a High Density Polyethylene (HDPE) matrix at different temperatures were completed in this paper. The test temperatures ranged from -60 °C to 60 °C, with a temperature difference of 20 °C for each group. All samples exhibited tensile brittle fracture. The test results showed that the tensile strength of the specimens decreased continuously with increasing temperature. Taking 0 °C as the reference temperature, the ultimate strength of the sample at -60 °C was 1.63 times that at 0 °C. When the temperature was 60 °C, this value was 0.41. Then, it can be calculated that the ratio of the strength of the sample at -60 °C to that at 60 °C was approximately 3.93, and the corresponding ratio of the elastic modulus was approximately 4.52. This shows that the mechanical properties of WPC are sensitive to changes in temperature. The variation coefficient of the average strength and elastic modulus of WPC for different specimens at different temperatures was less than 0.17, showing good stability due to the small dispersion of mechanical properties among different samples at any specific temperature.

Tensile, flexural and fracture properties of MEX-printed PLA-based composites

Due to the continuous development of material extrusion-additive manufacturing (MEX-AM) technology, the fracture behavior of polymeric parts, and especially of their associated composites, presents some shortcomings and also a challenge in the field. In this paper, the fracture properties of non-reinforced (NR) and reinforced Polylactic Acid (PLA) samples manufactured by MEX-AM process are investigated through tensile, flexural and fracture mechanics tests. The samples are reinforced with glass fibers (GF-PLA), carbon fibers (CF-PLA) and bronze particles (BP-PLA), and tested parallel (named FLAT for all tests) and normal (named UPRIGHT for tensile test, and ON-EDGE for flexural and fracture mechanics tests) to the layer growth (LG). It was found that regardless of the type of test, the LG and the material significantly influence the mechanical properties and collapse modes of the MEX-printed samples. It was obtained that the parallel-LG load is favorable for the tensile and flexural tests, and the normal-LG for the fracture mechanics tests. Overall, the NR-PLA material gives the best strength, strain and energy absorption properties, CF-PLA stands out as the stiffest material, while BP-PLA presents the minimum performances for almost all properties. The macroscopic analyzes of the fractured samples clearly highlight distinct failure mechanisms associated with each type of test, material and LG. From the analysis of the mechanical behavior and macrostructural images, CF-PLA was identified as the most brittle material, and NR-PLA the most ductile.

Tensile and impact properties of thermoplastic fibre hybrid composites based on air textured commingling hybrid yarns composed of carbon/aramid/polyamide 6 and carbon/glass/polyamide 6 filament yarns

This paper reports a comparison of tensile and impact properties between carbon/aramid and carbon/glass fibres reinforced unidirectional thermoplastic hybrid composites. For this purpose, different hybrid composites were produced using commingled hybrid yarns of carbon/aramid/polyamide 6 filament yarns and carbon/glass/polyamide 6 filament yarns with a defined mixing ratio based on air texturing technology. The results show that the density and specific Youngs’ modulus of the composites changes linearly with the proportion of carbon/glass and carbon/aramid fibre in hybrid composites. The specific Young’s modulus decreases linearly with decreasing carbon fibre content in the hybrid composites. On the other hand, the specific tensile strength does not change linearly according to the rule of mixture and a negative hybridization effect can be observerd for both types of hybrid composites. Furthermore, the combination of carbon/aramid and carbon/glass fibres can increase the impact strength by approximately 204% and 218%, respectively, compared to the composite reinforced by CF only. Although the specific tensile strength and specific impact strength of carbon/aramid reinforced hybrid composites are higher than those of CF/GF hybrid composites due to the lower density of carbon/glass hybrid composites, the potential impact strength achievable in hybrid composites is higher with the carbon/glass combination than with the carbon/aramid combination.

Thermo‐mechanical properties of epoxy composites filled with inorganic particulate fillers for robust solder mask application

AbstractFiller components play a crucial role as thermo‐mechanical reinforcement to the epoxy‐based solder mask, ensuring effective insulation and passivation. This study investigates the impact of different inorganic filler types (talc, silica (SiO2), boron nitride (BN) and barium sulfate (BaSO4)) and loadings (5 and 15 wt%) on the tensile and thermal properties of the epoxy composites. The composites were blended, cast and thermally cured. Of these composites, only 15 wt% SiO2/epoxy composite exhibits notable increments in both tensile strength and modulus, surpassing unfilled epoxy by 11.65% and 31.9%, respectively. It also displays the highest elongation at break, supported by small particle size, high specific surface area and minimal void volume fraction. For thermal tests, the addition of all fillers increases the storage modulus in both glassy and rubbery regions, especially 15 wt% talc/epoxy composite with 30.09% increment at 25 °C. Additionally, all fillers raise the glass transition temperature (Tg), notably improving it by 9 °C in the 15 wt% BN/epoxy composite. Moreover, their inclusion generally enhances the onset decomposition temperature (Tonset) and reduces weight loss during decomposition. © 2024 Society of Chemical Industry.

Optimization, Sodium Hydroxide and Plantain Fibres: Mechanical Properties of Unsaturated Polyester Composites for Transtibial Prosthetic Socket

Low mechanical behaviors of natural fibres in the reinforcement of polymer composites have remain an issue of concern. This study is aimed at investigating the effect of NaOH treatment on the mechanical properties of plantain fiber for the transtibial prosthetic sockets made of polyester resin. Plantain fiber was extracted from the plantain bast using water retting techniques. The fibres were modified using alkaline treatment method of 5 – 25% for variable time of 30 to 150 minutes. It was optimized using 3-level Factorial design (3-LCD) of response surface methodology based on tensile properties of treated fibres. The polyester composites of plantain and glass fibers were prepared using hand-layup techniques. Instron Universal testing machine-3369 model was used to determine the tensile and impact properties of fibers and polyester composites. Rockwell hardness tester-RBHT/S-39 model was used to determine the hardness property. The optimum process conditions of 5 % NaOH for 119 minutes improved plantain fiber tensile strength, modulus, strain, energy, and extension by improved by 102.03, 208.07, 9.70, 210.52 and 205.73 %, respectively. The ultimate tensile strength and modulus was obtained at 10 and 12.5% fiber loading. The hardness and impact strength of NaOH modified unsaturated polyester composites was marginally more than 3.51 and 10.69% of glass fiber reinforced unsaturated composites, respectively, at 12.5% fiber loading. FTIR analysis revealed the improvement in mechanical properties. Thus, NaOH modified plantain fiber unsaturated polyester composites serves as a better alternative for making transtibial prosthetic socket.

Utilizing decommissioned windmill blades as reinforcement or filler for biocomposites

Decommissioned or damaged windmill blades and other wastes have limited applications and are generally disposed into landfills or incinerated. Increasing generation of wind energy will also lead to increase in blades available for disposal. It is estimated that more than 800,000 tons of blades will be available annually for disposal from 2050. Blades contain glass, carbon, resins and other valuable materials and hence it is prudent to develop methods to reuse or recycle the blades. In this study, we have used windmill blade waste (WBW) as reinforcement for polypropylene (PP) and also as filler/additive for coir-WBW-PP hybrid composites. Various proportions of the components were made into composites and studied for the changes in mechanical, acoustic, thermal and noise insulation properties. Tensile strength did not show major increase in properties whereas 70/30 WBW/PP composites had highest flexural strength and modulus. Addition of WBW considerably increased both the tensile and flexural properties of the hybrid composites with up to 180% increase in flexural strength and 173% increase in modulus. Similarly, hybrid composites had better thermal conductivity and the composites containing 80% WBW and 20% PP had the highest thermal conductivity. Coir improved the acoustic sorption due to the presence of pores and voids in the composites whereas WBW acts as filler and decreased the sound sorption. WBW can be effectively used as reinforcement or filler for PP based composites.

Investigations on the development of impact-resistant thermoplastic fibre hybrid composites from glass and steel fibre

With the increased use of fibre reinforced composites (FRP), the design of new generation of composite structures with high stiffness and a ductile material behaviour is required to cope with complex load scenarios and high damage tolerances. This can be achieved, in particular, by a combination of conventional fibre-reinforced composites (FRP), which possess high stiffness and strength with metallic materials characterized by their high ductility and associated higher energy absorption capacity. Currently, there are no solutions for hybridisation of high performance filament yarns, metal filament yarns and thermoplastic filament yarns on micro level. Therefore, the main objective of this study is to develop a fibre hybrid composite based on hybrid yarn consisting of glass, steel and polypropylene filament yarns and to compare its tensile and impact properties with those of the composite reinforced only with glass filament yarn. The tensile and impact properties of the unidirectional hybrid composites produced from the developed multi-material hybrid yarn consisting of steel, glass and polypropylene filament yarns are compared with those of a non-hybrid composite reinforced exclusively with glass filament yarn. The results show that by hybridising with steel fibres a characteristic post-failure behaviour can be achieved, so that the developed multi-material hybrid yarns have a high potential for use in composites with high crash and impact performance requirements, where safety demands are essential.

Preparation and characterization of carbon fiber spread tow needled preform and its composite based on novel short yarn needling method

AbstractDue to the high fiber volume fraction of carbon fiber spread tow plain weave fabrics, it is difficult for short fibers to be brought into the thickness direction to form needled fiber bundles during the needling process. The interlaminar performance of the carbon fiber spread tow needled preform is weak, and the in‐plane damage is also severe. Responding to this issue, this article proposed a new method for preparing carbon fiber spread tow needled preform based on short yarn needling, which was expected to manufacture high‐performance carbon fiber spread tow needled preform and composite. We conducted experimental research on the preparation and structural characterization of the preform, as well as the Mode I interlaminar mechanical properties and in‐plane tensile properties of composites. The results showed that the fiber volume fraction of the preform significantly increased, reaching to 55.7%–56.1%, which was 25.5%–25.9% higher than that of traditional needled preform. The Mode I interlaminar property of carbon fiber spread tow needled composite reached to 905–4376 J m−2, which was improved by 29.3%–525.1% and 125.8%–1054.6% compared to traditional needled composite and laminated composite, respectively. At the same time, the tensile strength and tensile modulus were also improved by 191.5%–212.2% and 66.2%–78.1% compared to traditional needled composites. The preparation method of carbon fiber spread tow needled preform based on short yarn needling has laid the foundation for the 3D printing molding of dry fiber fabrics and is expected to be applied to high‐quality needling of high thickness and large curvature‐shaped fabric preforms.Highlights A novel method was proposed for preparing high‐performance carbon fiber spread tow needled preform based on short yarn needling. The fiber volume fraction of novel carbon fiber spread tow needled preform significantly increased, reaching to 55.7%–56.1%. The GIc of the novel carbon fiber spread tow needled composite was improved by 29.3%–525.1% compared to the traditional needled composite. The tensile strength and tensile modulus were also improved by 191.5%–212.2% and 66.2%–78.1%, compared to traditional needled composites.

Stacking Sequence and Weight Fraction Effect on Tensile and Flexural Properties of Woven Jute and Woven Carbon-Jute Reinforced Polyester Composites

Hybrid composites are a category of composites in which more than one types of fiber are used to reinforce the matrix. In this work, the mechanical properties of jute woven & and carbon-jute woven reinforced polymer matrix hybrid composites were evaluated to assess a comparative study between the two configurations varying the stacking sequences. Specimens of composites were prepared by hand layup process. To observe the effect of fiber weight fraction on properties, two types of composites were made having matrix-fiber weight fractions of 85:15 & and 80:20. Moreover, by altering the stacking sequences of the composites, these properties were also examined for the carbon-jute reinforced polymer matrix composites. It was observed that a hybrid jute-carbon composite having a stacking sequence of j/c/j/c/j and weight fraction ratio of 80:20 exhibited a better tensile strength of 108.795(10.885) MPa and Young’s modulus of 6.052(0.489) GPa. Superior flexural strength of 150.41 (±7.501) MPa and flexural modulus of 6.845(±0.825) GPA were found in hybrid jute-carbon composite having stacking sequence of j/c/j/c/j/c/j/c/j that has a weight fraction ratio of 80:20. In both cases, better mechanical properties were found for hybrid composites with higher fiber content and having alternate stacking sequences.

Mechanical and tribological properties of silicon carbide /carbon fiber/epoxy resin based composites

In this contribution, an epoxy resin based composites which synergistically modified by carbon fiber (MCF) and silicon carbide (SiC) particles were prepared. The chemical structure of MCF and SiC before and after surface treated using silane coupling agent were analyzed by Fourier transform infrared spectroscopy and X-ray diffraction, respectively. The mechanical properties including tensile, flexural, and compression of the composites were investigated. Moreover, the friction and wear performances were studied on a ball-on-ring wear tester. The results indicated that the best tensile, compressive, and friction and wear properties of composites were obtained when SiC particles content is 3.0 wt.%. Compared to the pure epoxy resin, when the SiC particles content is 4.0 wt.%, the best flexural strength and modulus were obtained, which increased by 8.7% and 52.97%, respectively. Both the average coefficient of friction (COF) and the wear mass losses of the composites decreased significantly with the addition of the modified SiC particles. In addition, the main wear mechanism of pure EP is adhesive and fatigue wear, while the SiC/MCF/EP composites exhibit abrasive and fatigue wear.

Using polyethylene terephthalate bottle waste as a viable precursor for the synthesis of unsaturated polyester resin in fabrication of jute fibre reinforced composites

The present research effort employs glycolysed polyethylene terephthalate (PET) bottle waste as a precursor for the synthesis of unsaturated polyester resin (rUPR). This resin is then used for manufacturing composites that are reinforced with jute fibres using the sheet moulding compound technique. The limited crosslinking of styrene in the rUPR was elucidated using a combination of differential scanning calorimetry (DSC) and Fourier transform infrared spectroscopy (FTIR) analysis. The elevated exothermic reaction energy of 1152 kJ and the clearly identifiable peak observed at 1620 cm−1 in the Fourier Transform Infrared (FTIR) spectrum provided substantial evidence for this phenomenon. Additionally, the X-ray diffraction (XRD) analysis indicated that the recycled unsaturated polyester resin (rUPR) demonstrated a higher level of amorphous nature This observation can be attributed to reduced viscosity and enhanced ductility of rUPR. The utilisation of the rUPR as a matrix material has shown significant effectiveness in enhancing the tensile and flexural properties of composites reinforced with jute fibres. Thereby, the objective of this research is to develop a thermoset resin using recycled polyethylene terephthalate (rUPR) waste material for identification its suitability in manufacturing composites with jute fibres as reinforcement.

Study on the structure and thermal properties of graphite/copper laminated composites assembled by Ti-containing active filler metals

The development of high-power and small-sized electronic components requires the emergence of heat management materials with high heat flux. Hence, Ti-containing filler was used to braze graphite film/Cu high heat flux composites. The microstructure and forming mechanism of joints were studied, the influence of temperature on joint formation was analyzed, and the influence of graphite volume fraction on the thermal properties of the composites were discussed. The results show that the main microstructure of graphite/copper joints are Cu(s,s), Ti6Sn5 and CuTi2. As the brazing temperature increases, the carbide layer (TiC) that affects the connection gradually thickens, from <0.5 μm at 800 °C to 3 μm at 850 °C, which deeply improve heat transfer of composite materials. The tensile properties of composites also increase with increasing temperature, maximum tensile strength 31.94 MPa can be obtained at 850 °C. Furthermore, the composites are proved to possess high heat flux during process of heat transfer, and the transfer rate was 1.77 times that of Cu, 3.72 times of Al. The temperature rise test carry out in hot bench intuitively demonstrating that the composites have faster heating rate. Al used 197 s to raise from 25 °C to 50.5 °C, Cu used 140 s, while 76.92 % graphite-contained composites only took 75 s in the same volume and experimental condition.

Tensile properties of thermoset composites based on yarn structures from recycled carbon fibre and low melting temperature Co-polyamide fibre

The tensile properties of thermoplastic composites based on hybrid yarn structures consisting of recycled carbon fibre (rCF) and thermoplastic fibres (rCF content of the hybrid yarn approx. 50–60% by weight) have been reported previously. To date, no report has been found on the tensile properties of thermoset composites based on yarns with high rCF content (&gt;90% by weight). The reasons for this are the complex mechanisms involved in processing pure rCF due to the low shear strength, smooth fibre surface, small fibre diameter and high brittleness of rCF. Yarns made of rCF (≥90% weight) for thermoset composites have been developed in a fundamental research project at the ITM. This paper reports on the tensile properties of unidirectional composites based on yarns composed of staple rCF (&gt;90%) and low melting co-polyamide fibres produced by varying spinning parameters. Furthermore, in order to increase the infiltration of the epoxy matrix during the composite manufacturing process, the yarns are thermally treated at 180°C prior to infiltration and its effect on the tensile properties of the composites is analysed. The results show that the thermal treatment of the yarn prior to infiltration with the matrix, compared to the yarn without prior thermal treatment, helps to achieve better impregnation and therefore better tensile strength of the composites compared to the yarn without prior thermal treatment. A Youngs’ modulus and tensile strength of 86 ± 11 GPa and 1181 ± 71 MPa respectively are achieved in thermoset composites based on the developed yarns.

Tensile Properties of Aluminum Matrix Composites Produced via a Nitrogen-Induced Self-Forming Process

This study compares the tensile properties of commercial aluminum matrix composites (AMCs) with those of AMCs produced via a nitrogen-induced self-forming process. This process is a newly developed AMCs manufacturing process that takes advantage of the price competitiveness and productivity of large-scale products produced via the liquid process. Additionally, this process has the freedom of choice of the reinforcement phase and the homogeneous dispersibility of the powder process. Compared to commercial monolithic 6061 alloys, 6061 aluminum alloy matrix composites exhibit increased Young’s modulus, yield strength, and ultimate tensile strength by 59%, 66%, and 81%, respectively. This study also compares the tensile properties of AMCs with different matrix compositions, including 2009 and 7050 aluminum alloys. The study shows that AMCs produced using the nitride-induced self-forming aluminum composite (NISFAC) process exhibit comparable or superior tensile properties to those obtained using existing commercial powder metallurgy (P/M) processes.

Bimodulus constitutive models and the simulation on bending properties of woven carbon fibre-reinforced composites

The tensile and compressive properties of woven carbon fibre-reinforced composites (CFRP) are different owing to the buckling and entanglement of fibre bundles. Two bimodulus constitutive models (TBM and PBM) were proposed based on the track stress criterion and principal stress criterion. Combined with the Hashin three-dimensional strength criterion and Alvaro stiffness reduction criterion, a material subroutine was written to calculate the bimodulus constitutive models. Three-point bending tests of [0/90]20 and [±45]20 were designed to obtain the load–displacement curves and failure modes. The precision of the calculation results with the traditional unimodulus model and bimodulus models were compared, and the bending performance of woven CFRP was explored. The results demonstrate that fibre fracture and interlayer damage occur with different stacking sequences. The material properties can be better shown with less error as bimodulus models. The stiffness and strength of the PBM were slightly larger than those of the TBM, and the failure factors were smaller than those of the TBM. The results of the TBM are closer to the test, and the material subroutine is easier to realise. Bimodulus constitutive models have good application prospect in woven composites for higher accuracy.

Effect of weight of Nanoclay on Tensile, Flexure and Toughness properties of Glass Epoxy composites

In recent times, polymer composites have played an epochal role in transforming material science. Some of their properties such as toughness, strength, flexibility, and rigidity have helped them supplant conventional materials such as iron, steel, and aluminium on several occasions. Apart from this, they are light in weight and more cost-efficient, which make them a viable alternative. They have found their application in several fields such as automobile industry, aerospace industry, construction, and pipeline industry. The present investigation uses composite material fabricated with varying weight percentages of Nano clay viz 1.5, 3.5, and 5 which are compared with Neat Glass Epoxy composite. The reinforcement material used is Glass fibre. Three different orientations viz unidirectional, Symmetric and Asymmetric of the laminate are considered. The fabricated composite is characterized for various mechanical properties like tensile test, flexure, and Fracture toughness testing as per ASTM standards. The addition of Nano Clay showed the improvement in the Tensile, Flexure and Fracture Toughness of the for 3.5 wt% of Nanoclay. The properties under tensile loading i.e. the tensile strength is increased by 12% for Unidirectional laminate, flexure strength increased by 20% for Unidirectional laminate and 20% for Unidirectional laminate fracture Toughness.after 3.5 wt%, there seemed to be a decline in both the properties. The morphological assessment was done by scanning electron microscopy (SEM) where the microstructure was analyzed. The SEM images were used to study the activity of the Nanoclay within the fabricated composite. The overall test results suggested that the fiber reinforced nanoclay composites can fit for industrial applications like condenser blades and turbine blades.

Effects of polypropylene and basalt fibers on tensile and compressive mechanical properties of fiber-reinforced ice composites

As an environmentally friendly and low-cost construction material, ice has a rich historical usage and has been gaining significance in cold-zone engineering constructions. However, the low tensile strength and brittle damage characteristics limit the potential applications of ice. Incorporating fibers in ice has been recognized as an effective method to improve the mechanical properties. This research aims to investigate the effects of polypropylene fibers (PF) and basalt fibers (BF) on the mechanical properties of fiber-reinforced ice composites. To do so, approximately 200 PF- and/or BF-reinforced ice specimens with varying fiber contents (0 %, 2 %, 4 %, 6 %, 8 %) were produced and subjected to splitting tensile and uniaxial compressive tests at −10 °C. Besides, the synergistic effect of hybrid fiber-reinforced ice on tensile mechanical properties was further investigated. The experimental results demonstrate that the addition of fibers transforms the brittle failure of ice into ductile failure, and both BF and PF improve the tensile and compressive mechanical properties of ice composites in strength and ductility as functions of fiber contents. The tensile mechanical properties of hybrid fiber-reinforced ice exhibit both negative and positive synergistic effects. Furthermore, the research established the tensile and compressive strength formulas of PF- or BF-reinforced ice composites with different fiber contents, and the calculated results correlated well with the tested ones.

The flexible stab‐resistant composite membrane made by thermoplastic polyurethane filled with modified nanoparticles

AbstractThermoplastic polyurethane (TPU) has good elasticity and tear resistance, and is often applied in the field of flexible puncture resistance although the puncture resistance of pure TPU is limited. In this paper, silica powder (SiO2) and styrene butadiene rubber powder (SBR) with different concentrations were used as fillers to reinforce the TPU matrix respectively. To overcome the problem of poor interfacial compatibility between filler and matrix, the silane coupling agent r‐Aminopropyltrieth oxysilanee (KH550) was selected to modify the particles. The compatibility of particles and matrix, the puncture properties and tensile properties of composites were assessed by FTIR, TEM, SEM, tensile testing, and needle puncture testing. Further, the tensile and puncture properties of composites with different types and concentrations of particles were systematically compared and analyzed to find optimal parameters. The results show that the best modification effect is gained when the mass ratio of KH550 and nanoparticles is 0.85:1 and the specific puncture strength of TPU membranes incorporated modified SiO2 or SBR nanoparticles can be increased by up to 106.4% and 85% respectively compared to pure TPU membrane.
