Evaluation of the mechanical properties of hybrid composites reinforced with plant fibers

The incorporation of plant fibers into the matrix plays an interesting role. Natural fibers have been widely used as reinforcements in polymer matrix composites. Among all reinforcing fibers, natural fiber-based hybrid composites have attracted the attention of researchers as high-potential reinforcing materials for composite materials. These fibers are easily available in the form of agricultural products. Natural fibers are inexpensive, durable and lightweight materials for composite applications. In this experimental work, sisal fibers and date palm fibers were used as reinforcement in different ratios to fabricate hybrid composites by compression molding technique while maintaining a total fiber loading of 20 % by weight. Tensile tests, flexural tests, and impact tests were carried out, water absorption was also determined. The results obtained show that the composite composed of a combination of 16% sisal fibers and 8% date palm fibers has better tensile properties with a stress value of 6.88 N/mm2 and a value of Izod impact of 43.218 J/m. As well as both composites showed a better bending stress value of 67.29 N/mm2, the water absorption test was carried out for four days with 120 hours analysis. This research focuses on the fact that specimen-2 containing 16% sisal and 8% date palm fibers absorbs less water than other composites.

Mechanical properties of web kapok/fiberglass-epoxy hybrid composites for marine structures

Abstract This study investigates the mechanical properties of hybrid composites composed of web kapok fibers and fiberglass reinforced with epoxy for potential application in the marine industry. The web kapok fibers were carefully processed using a carding technique to ensure better alignment and consistency. Various composite configurations were produced, and extensive mechanical testing was conducted, including flexural, tensile, and impact tests. The results revealed that the presence of two web kapok fiber layers within the composite significantly increased flexural strength and flexural modulus compared to pure fiberglass laminates. However, a single layer of web kapok fabrics exhibited the highest tensile strength, although it decreased with additional layers. The impact strength of these hybrid composites also showed promising results, especially when compared to raw fiberglass composites. Moreover, these composites exhibited improved resistance to water absorption and corrosion, making them potentially suitable for marine applications. This research highlights the potential of web kapok/fiberglass hybrid composites as an eco-friendly alternative for marine engineering, with implications for reduced environmental impact and sustainable technology in the industry.

An Experimental Study of the Properties of Carbon Fiber/Epoxy Composites Mixed with Rubber Granules

In this research work, the mechanical properties of hybrid composites reinforced with woven carbon fiber mats particulated with natural rubber powders as fillers in the epoxy resin matrix were investigated. The specimens were prepared by the hand-layup process followed by a vacuum bag moulding process. The vacuum moulding reduces the voids or cavities in the hybrid composites. The natural rubber powder was added in different weight proportions (5%, 10%, 15%, and 20%), and carbon fiber is added in 20% for all the specimens. Experiments such as tension testing, flexural testing, water absorption/acid corrosion/base corrosion tests, dynamic mechanical analysis (DMA), and scanning electron microscopic (SEM) analysis were conducted to evaluate the epoxy carbon rubber (ECR) composites. The tensile and flexural test findings demonstrated that the addition of 10% natural rubber particles gave better results as compared with other proportions. The water/acid/base absorption test findings reveal that the ECR composites are not affected by water/acid/base. The DMA teat findings show that ECR composites having 10% natural rubber have higher damping factor, storage, and loss modulus. The SEM analysis shows that ECR hybrid composites with 10% rubber particles contained a uniform distribution of rubber particles over reinforcement, and also, there were no cracks and voids. According to this research findings, ECR hybrid composites with 10% natural rubber particles prepared during the vacuum bag moulding process can be used to prepare aerospace interior components.

The effect of hybrid thermal fillers on thermal conductivity of carbon fiber reinforced polybutylene terephthalate composites

AbstractThe use of functional polymeric composites with superior thermal properties, capable of replacing conventional polymers, has increased in recent years, particularly in the electrical‐electronics sector where thermal management is crucial. Carbon fiber (CF) polymer–matrix structural composites have relatively high in‐plane thermal conductivity but low through‐plane conductivity. In order to further enhance the through‐plane and in‐plane conductivity of CF‐reinforced polybutylene terephthalate (PBT) composite, a hybrid loading approach was employed, incorporating synthetic graphite (SG), boron nitride (hBN), aluminium nitride (AlN) and graphene (G) in composite formulations. It was found that the in‐plane conductivity of PBT‐20CF‐20SG‐3G and the through‐plane conductivity of PBT‐20CF‐20SG‐3AlN are 69% and 25% higher, respectively, than those of PBT‐40CF. However, the mechanical properties of hybrid composites exhibit lower values compared to those of CF‐reinforced PBT composites. The tensile strength value of PBT‐40CF is about 33% and 57% higher than those of PBT‐20CF‐20SG‐3G and PBT‐20CF‐20SG‐3AlN. Moreover, the flexural strength of PBT‐40CF is about 48% and 38% higher than those of PBT‐20CF‐20SG‐3G and PBT‐20CF‐20SG‐3AlN, respectively. The density value of PBT‐40CF is lower than that of the composites of PBT‐20CF‐20SG. From TGA it was observed that the thermal stability of PBT‐40CF is comparable to that of the composites PBT‐20CF‐20SG. From the conducted study, it can be proposed that the hybrid combination of SG, hBN, AlN and G can be utilized to achieve higher thermal conductivity values, instead of relying solely on CF in the composites. © 2024 The Authors.

Modifying the properties of polyamide 6 with high‐performance environmentally friendly nano‐ and microsized reinforcing materials

AbstractIn this study, we investigated the morphological and mechanical properties of hybrid composites with a polyamide 6 (PA6) matrix and reinforced with basalt fibers (BFs) and halloysite nanotubes (HNTs). The presence of reinforcing materials fundamentally changed the behavior of the molecules, which was morphologically manifested in the change in the ratio of the rigid and the mobile amorphous phase. The x‐ray diffraction and transmission electron microscopic images showed the crystal nucleating effect of the halloysite nanotubes. Based on these, we concluded that around the basalt fibers, an interphase is formed, while around the nanoparticles, a two‐layer interphase is created, the inner layer of which is semicrystalline, while the outer layer is rigid amorphous (RA). The nanoparticles are surrounded by a semicrystalline interphase, which is surrounded by an RA interphase. This overlaps with the interphase of the basalt fibers, therefore the halloysite nanotubes can effectively help the stress transfer from the matrix to the basalt fibers. The mechanical properties of the samples also reflected this: the hybrid composites had a significantly higher tensile modulus, tensile strength, and an unchanged elongation at break compared to the composite reinforced with only basalt fiber.Highlights Environmentally friendly polyamide 6 matrix hybrid composites were prepared. Uniform distribution of halloysite nanotubes was achieved. Enhanced mechanical properties were observed for hybrid composites. Halloysite nanotubes aid stress transfer from matrix to basalt fibers. Halloysite nanotubes act as crystalline nucleating agents.

Tensile, bending, and impact properties of laminated carbon/aramid/glass hybrid fiber composites

Abstract In this study, hybrid (carbon, glass, and aramid) fabric epoxy composite laminates were fabricated with different layering sequences by hand lay-up. The effects of layering arrangements of laminated composite fibers on the mechanical properties of hybrid composites were investigated. Tensile, bending, and impact tests were performed to obtain the mechanical behaviors of hybrid composites. It was found that the layering sequences significantly affect the tensile, bending strength, and impact energy. As a result of the tensile tests, the highest tensile strength was obtained in the 3C + 3G combination. The highest load-carrying capacity in three-point bending tests was obtained in the 2G + 2A + 2C combination. The combination with the highest impact energy was 2C + 2G + 2A, and the lowest was 3C + 3G. It has been observed that hybrid composites containing aramid fiber absorb higher impact energy than others. The results showed that the layering sequences are essential in hybrid composites with the same fiber and layer number.

Effect of graphite on flax/E-glass/epoxy hybrid polymer composites for its tensile properties: Hybrid polymer composites

In their quest to develop lightweight biodegradable materials for automobile applications, researchers have been pushed to go from synthetic to natural fibres to a large extent. As a result, an experimental study is conducted to assess the implications of stacking configuration, secondary reinforcement and graphite loading on the mechanical properties of hybrid composites (i.e., e-glass/flax/graphite epoxy composite). Different laminates of various loadings of graphite particles are fabricated by hand layup vacuum bagging method of four plies, one group of composites are fabricated by flax fiber as skin layer, E-Glass fiber as core layer and other group of composites are vice versa. The obtained specimens are subjected to a tensile test as per the ASTM standards. The interval plots, probability plots, pareto charts are plotted using Minitab statistical tool to understand the effect of graphite along with the interaction of other parameters. Regression analysis is carried out to develop an empirical equation with a 95% confidence limit for all intervals which fits linearly. According to the findings, the characteristics of hybrid polymer composites are slightly improved with the addition of graphite particulate as one of the reinforcements from 3 wt% to 9 wt% for tensile strength. When comes to stacking sequence, E-Glass utilized as skin layer and treated flax employed as the core layer, showing improved tensile strength of 187.45 MPa. Then the laminates with Flax/E-Glass/Graphite reinforced epoxy composites are serving good enough for medium load structural applications, hence hybridization is recommended.

Composite materials offer huge upgrades over current accessible materials for various primary applications because of their fantastic mechanical qualities and moderately low thickness. Carbon filaments are most broadly utilized in vehicle, aviation, military and transportation of oil, gas and water applications. The specimen is prepared with varying stacking sequences (i.e., Carbon-Sisal- Carbon-Sisal [CSCS], Carbon-Sisal-Sisal-Carbon [CSSC] and Sisal-Carbon-Carbon- Sisal [SCCS]) and Carbon, Carbon, Carbon, Carbon (CCCC) and four carbon weight fraction (i.e., 2%, 4%, 6% and 8 %) with 2% of SiC. At the point when composites are used in water, oil and gas transportation, the lines are encountering high disintegration and burden. To learn about the impact of disintegration and burden, the malleable, flexural, influence, twofold shear and wear test are completed to comprehend the disintegration and conveying attributes of industrial applications. In this undertaking, the mechanical properties of composites on epoxy resin with sisal and carbon fiber have been considered. The result shows that the mechanical properties of carbon based samples shows that the better result as compared with other samples.

A comparative study on the mechanical properties of African teff and snake grass fiber-reinforced hybrid composites: effect of bio castor seed shell/glass/SiC fillers

Abstract The environmental awareness and sustainable nature of plant-based fibers have forced material researchers and automakers to use natural fibers instead of petroleum-based fibers for various industrial applications. The need for environmentally and biodegradable fibers has created a demand in the transportation industry. In this study, bio castor seed shell (C), glass fiber (G), and SiC (SC) fillers in a constant weight fraction (10 %) were reinforced separately with varying weight fractions (5–25 %) of African teff and snake grass fibers to improve the mechanical properties of the hybrid composites. Both African teff and snake grass fibers were subjected to alkaline treatment to remove amorphous elements such as hemicellulose, lignin, and wax, resulting in high surface roughness. The hybrid composites were fabricated by the compression molding technique and their mechanical properties were characterized as per ASTM standards. The fractured surface of the treated fiber was examined by scanning electron microscopy. From the results, it was found that SC10SG20AT showed maximum mechanical properties compared to C10SG20AT and G10SG20AT due to higher load-bearing capacity of SiC filler. Therefore, SC10SG20AT can be recommended for lightweight applications.

Investigation of the effects of hybridization types and temperature on the quasi‐static indentation properties of glass/flax hybrid composites for various test speeds

AbstractHybridizing man‐made fiber composites with natural fibers has been chosen for numerous structural or semi‐structural applications over the last several decades. Even though several studies have been conducted to determine the mechanical properties of inter‐ply hybrid composites, the effects of hybridization on the out‐of‐plane mechanical properties of hybrid composites still need to be clarified. The mechanical properties of hybrid composites at low temperatures are another significant matter to be elucidated. In this study, E‐glass and flax yarns were used to produce woven fabrics to obtain intra‐ and inter‐ply hybrid composites. They were then subjected to the quasi‐static indentation test at −30°C, 25°C, and 60°C. It was concluded that, according to the hybridization type, an improvement or decrease can be obtained in the mechanical properties of hybrid composites. The contact force and energy absorption properties of pure glass composite could be increased at 8.88% and 3.87% proportions respectively, thanks to the intra‐ply hybrid composite‐1 in the study. Furthermore, the through‐thickness properties and damage mechanisms of hybrid composites were profoundly affected by the temperature.

Experimental investigation on mechanical properties of Kenaf fibre reinforced epoxy composites with annona squamosa powder

The adoption of biodegradable and environmentally-friendly composite materials is gaining momentum in diverse engineering sectors due to their growing popularity. The present investigation focuses on analysing the influence of fibre treatment on the mechanical properties of hybrid composites made of Kenaf fibres and epoxy matrix. The fibre is subjected to NaOH treatment initially, which is subsequently followed by a comprehensive drying process. The second scenario involves the utilisation of custard apple seed powder, a biodegradable filler material, to modify the matrix. The utilisation of microscopy is employed as a means to analyse the modified fibres and to identify any potential surface alterations that may have taken place. Following this, epoxy composites are fabricated by utilising modified and unmodified Kenaf fibres through a basic hand layup method with vacuum bagging. The composites that have been prepared are subsequently evaluated for their characteristics through tensile and flexural measurements, in compliance with the applicable ASTM standards.

Effect of precipitation hardening treatment on hardness and tensile behaviour of stir cast LM4 hybrid composites through TEM and fractography analysis

LM4 hybrid composites reinforced with TiB2 and Si3N4 are fabricated using a two-stage stir casting method and are subjected to precipitation hardening treatment. The efficacy of TiB2, Si3N4, and precipitation hardening treatment on LM4 was investigated. When compared to as-cast LM4, all hybrid composites had displayed better hardness and UTS values. This increase in mechanical properties of hybrid composites may be attributed to the presence of hard reinforcement particles, appropriate stirring parameters, which resulted in uniform reinforcement distribution free of porosity and agglomeration. It was observed that in as-cast condition hybrid composites with a higher wt.% of TiB2 had displayed improved hardness (12.5% higher) and UTS (4.4% higher) values than composites with a higher wt.% of Si3N4, because Si3N4 particles are 3.8 times larger than TiB2 particles. Precipitation hardening treatment enhanced the mechanical properties of hybrid composites, with multistage solutionizing (MSHT) and artificial aging at 100 °C producing the best results. Peak aged (MSHT + aging at 100 °C) hybrid composites exhibited 160, 178, and 202% improvement in hardness and 46, 34, and 30% improvement in UTS when compared to as-cast LM4. This increase in age hardened specimens properties is due to the formation of metastable phases, which were validated using XRD and TEM. Fracture analysis of these as-cast and peak aged hybrid composites revealed a mixed mode of fracture-mostly brittle type, because of the presence of reinforcements, intermetallic phases, and strong interface bonding between matrix and reinforcements.

Physical and mechanical properties of kenaf/flax hybrid composites

AbstractThis research investigates the physical and mechanical properties of hybrid composites made of epoxy reinforced by kenaf and flax natural fibers to investigate the hybridization influences of the composites. Pure and hybrid composites were fabricated using bi‐directional kenaf and flax fabrics at different stacking sequences utilizing the vacuum‐assisted resin infusion method. The pure and hybrid composites' physical properties, such as density, fiber volume fraction (FVF), water absorption capacity, and dimensional stability, were measured. The tests of tensile, flexural, interlaminar shear and fracture toughness (Mode II) were examined to determine the mechanical properties. The results revealed that density remained unchanged for the hybrid compared to pure kenaf/epoxy composites. The tensile, flexural, and interlaminar shear performance of flax/epoxy composite is improved by an increment of kenaf FVF in hybrid composites. The stacking sequence significantly affected the mechanical properties of hybrid composites. The highest tensile strength (59.8 MPa) was obtained for FK2 (alternative sequence of flax and kenaf fibers). However, FK3 (flax fiber located on the outer surfaces) had the highest interlaminar shear strength (12.5 MPa) and fracture toughness (3302.3 J/m2) among all tested hybrid composites. The highest water resistance was achieved for FK5 with the lowest thickness swelling.

Experimental Investigation on the Mechanical Properties of Hybrid Composites Made with Banyan and Peepal Fibers

ABSTRACT Industries demand a material with better strength and light weight for various applications. Natural composites are fulfilling the needs of industries partially. The purpose of the present research is to develop a new composite material with light weight and better strength. In this research, hybrid composites were fabricated by conventional hand layup method using natural fibers such as banyan and peepal. Totally, four composites were manufactured namely banyan (Epoxy: banyan: 70 wt%: 30 wt %), peepal (Epoxy: peepal: 70 wt%: 30 wt %), BPB (Epoxy: banyan: peepal: 70 wt%: 20 wt%: 10 wt %) and PBP (Epoxy: banyan: peepal: 70 wt%: 10 wt%: 20 wt %). Density and porosity of the composites were determined and the results showed that BPB composite exhibited a least density. Further, all the composites displayed the maximum porosity percentage of 5. Moreover, the mechanical properties like tensile, flexural and impact strengths were tested. The hybrid composite BPB showed 2.7%, 4.9% and 13.5% increase in tensile, flexural and impact strength respectively, compared to PBP composite. Furthermore, water absorption study was conducted and the results revealed that BPB composite absorbed less amount of water (9%) at the immersion time of 12 hours. Hence, it is suggested from the present investigation that the BPB hybrid composite could be a suitable candidate for the industrial applications with better mechanical properties and light weight.

Development and characterization of microstructural and mechanical properties of hybrid polystyrene composites filled with kaolin and expanded polyethylene powder

This study investigated the microstructural and mechanical properties of hybrid composites developed by the reinforcement of solvated polystyrene with expanded polyethylene powder and kaolin. The hybridized composites were synthesized using hand layup and cold mixing methods, and cured at room temperature for 3 days. The characterization was done using Fourier transform infrared spectroscopy (FTIR) and the scanning electron microscope coupled with energy dispersive spectroscopy (SEM-EDS), while the mechanical characteristics of the developed composites were evaluated by the Rockwell Hardness ASTM D785 standard. It was observed that an increase in kaolin content, at the expense of the polyethylene powder, increases the hardness strength of the composites, with the hardest composite (96.3 HRB) being obtained at a 25% kaolin mixer. The FTIR results revealed the presence of various functional groups, while the SEM analysis showed that the smoothness of the composite's surfaces increases with increase in kaolin content. The EDS analysis revealed the presence of several elements, mostly from the kaolin filler, suggesting the reason for its high density impacted on the kaolin/polyethylene filler composites. The importance of the study is the conversion of more than one solid waste into new and useful products.

Effect of MWCNT on mechanical characterization of glass/carbon hybrid composites

In this present study, the mechanical properties of Glass/Carbon hybrid composite reinforced with epoxy resin with and without multi-walled carbon nanotubes (MWCNT) were investigated. The composite under Experimental analysis were fabricated by using both Hand layup and Vacuum bag moulding processes. The main purpose of including MWCNT as a reinforcement material with epoxy is to reduce the existence of voids or cavities and to enhance the mechanical properties of Glass/Carbon hybrid composites. Because of their extraordinary mechanical properties and high aspect ratio, MWCNTs are considered to be ideal candidates for polymer reinforcement. The percentages of MWCNT selected for the study are 2%, 3% and 4% with the hybrid composites. The effect of MWCNT on mechanical properties such as tensile strength, compressive strength, flexural strength, impact strength, hardness and percentage of water absorption of the hybrid composites were determined as per American Society for Testing and Materials (ASTM) standards. The result from the study shows that the mechanical properties of hybrid composites were improved with the addition of small amount of MWCNT than without MWCNT. The fractured specimen from Tensile test is examined by using Energy Dispersive X-Ray Analysis (EDX)to study the alignment of the fibres, fibre-matrix adhesion, voids and filler agglomeration. This investigation provides proper guidelines to designers on enhancing mechanical properties of Glass/Carbon composite structures through MWCNT reinforcement for Aircraft structural components.

Physical and mechanical properties of hybrid composites using Kevlar fibre and nano-SiO2

ABSTRACT The current study aims to examine the mechanical and physical properties of Kevlar fibre/nano-silica/epoxy hybrid composites. The hand layup process followed by compression moulding was used to prepare a hybrid composite with different weight percentages (0%, 1%, 3%, and 5%) of nano SiO2 and four layers of the Kevlar fibres. Hardness, flexural, tensile, and impact tests were performed to evaluate mechanical properties. Nano SiO2 and Kevlar fibre improve the mechanical properties of the hybrid composites up to 3 wt.%. Rockwell Hardness tests suggest that the hardness of composites (K3) has improved up to 29% compare to K0. Tensile strength is about double at 3 wt.% nano SiO2 compared to neat laminates. The K3 has highest impact strength has increased by 50%. Flexural properties also increase up to 3 wt.% nano SiO2 reinforcement. Density, water absorption, and thickness swelling test wear were performed for the evolution of physical properties. Morphological analysis was done with the help of the field emission scanning electron microscopy (FESEM) technique.

Multiresponse Optimization of Mechanical and Physical Adsorption Properties of Activated Natural Fibers Hybrid Composites

In the current scenario, natural fiber-based biodegradable composites have increased because natural composite fibers are very cheap, biodegradable, lightweight, fireproof, and nontoxic. The present research work was carried out to optimize the mechanical properties of hybrid composites reinforced by Calotropis gigantea and hemp. To achieve these objectives, the following process parameters were determined, and RSM carried out optimization with the Box-Behnken experimental setup at three different levels: compression molding temperature (°C), pressure (bar), and time (min). The fibers were pretreated for 4 hours with a 5% NaOH solution to prevent moisture absorption. Regression equations were constructed to evaluate the mechanical properties, and the best process parameters were established. The results reveal that a pressure of 35 bar, a time duration of 7 minutes, and a temperature of 176°C are the best conditions for compression molding. The second aim was to compare CGF and hemp fiber-derived activated carbon adsorbents by determining physical adsorption properties, chemical compositions, and scanning electron microscope. Natural fibers were shown to be ideal candidates for manufacturing mesoporous activated carbon adsorbents with high surface area (1389–1433 m2/g), high mesopore percentage (63–68%), and high carbon content (80–87%). Even though hemp activated carbon had a greater mesoporous structure (69%) than CGF-derived activated carbons, the CGF-derived activated carbons had larger surface areas and higher C content.

Investigation on Mechanical Properties of Carbon Fiber Composite Using FEM for Leaf Spring Applications

Nowadays, many industries are shown interest in the hybrid composites, natural fibers, and reinforced materials due to reduction of the weight. The reason is that it will not affect environmental conditions. This experimental investigation identified the mechanical properties of hybrid composites. The hybrid composite materials are extensively used by E-glass/epoxy, carbon, and titanium alloy. Composites have good strength and less weight. The highest challenge of the automobile industry is to replace the steel leaf spring instead of the composite leaf spring. The composite structures have been providing better corrosion resistance. The conventional leaf spring experimental results were compared to analytical results of composite leaf spring. The design, simulation, and maximum stresses were done with the help of Ansys Workbench 15. Ansys Workbench materials are selected by titanium alloy, epoxy glass, aluminum alloy, and epoxy carbon. The design parameters were selected and analyzed to compare stress, deformation, elastic strain, and weight of the composite leaf spring as compared to conventional steel leaf spring. Deflection results were identified in the mechanical properties of the leaf spring. It should absorb shock loads and vertical vibrations due to road abnormalities. The composite experimental samples were analyzed using scanning electron microscopy.

Recycling and reinforcement potential for the fly ash and sisal fiber reinforced hybrid polypropylene composite

AbstractThe investigation explores mechanical, thermal and thermomechanical behavior of hybrid composites post‐recycling, and subsequent, 5 wt.% additional reinforcement to the recyclate of sisal (SSL) fiber fly ash (FA)/polypropylene (PP) hybrid composite. Impact of recycling and 5 wt.% of SSL fiber reinforcement of the recyclate on mechanical properties of hybrid composites made of 15–30 wt.% SSL and 5–15 wt.% FA were investigated. Noticeably, after recycling, a minimal loss of 2.39% only in tensile and 2.20% in flexural strength were recorded for the hybrid composites fabricated with 15 wt.% each of FA and SSL. The highest loss in tensile (10.32%) and flexural (4.22%) strength were reported for only 30 wt.% SSL fiber reinforced PP indicating that hybridization with FA has a benign effect on reducing property degradation. These lost properties were regained by reinforcing recycled composites with 5 wt.% of SSL fiber. Mechanical studies showed that the composite with 30 wt.% SSL fibers recycled and reinforced with additional 5 wt.% fibers showed a substantial improvement of ~10% and ~4% in the tensile and flexural strength while keeping the impact strength stable. FE‐SEM images confirmed a reduction (~67%) in aspect ratio of the SSL fiber due to reprocessing. DMA demonstrated a decrease of ~11% in storage modulus of the composites after first recycling. TGA confirmed an insignificant change in the degradation temperature of the recycled and re‐reinforced recycled composites versus fresh composites. The study paves the way for potential future recycling applications of waste natural fiber reinforced PP.
