Durable polymer composites preparation with oxy-delignified banana fiber for automotive parts: A study on mechanical and thermal properties

An innovative process route has been developed to produce modified banana fiber that are used as reinforcement in polypropylene composites for automotive parts. Banana fiber (BF) is modified through, Alkaline peroxide (APF), and oxygen delignification (ODF) treatment to obtain better adhesion and enhanced thermo-mechanical properties. The fiber-reinforced polymer (FRP) composites (10–30 % loading), were prepared through a specified configuration in a co-rotating twin screw extruder followed by injection molding. The results show that the ODF treatment with a 15 % NaOH concentration resulted in an 11-kappa number, which was lower than APF and untreated fiber. The highest improvement in tensile (31.27 ± 2.56) and flexural strength (44.880 ± 1.05 MPa) was achieved for ODF polymer composite and were 20.40 % and 35.6 % higher compared to the untreated fiber. The addition of natural fiber decreased the melt flow index to 7.56 gm/10 min with a slight decrease in hydrophilicity. The thermal stability was increased with enhanced melting, crystallization temperatures, and surface morphology.

Influence of Stacking Sequence on the Mechanical Properties of Banana-Glass Fiber Hybrid Laminates for Automotive Shells

The development of composite materials using natural fibers has garnered significant global research interest. Banana fibers, due to their abundant availability and rapid growth cycle, present a promising option for composite material development. When combined with synthetic fibers to form hybrid composites, the resulting material may exhibit significantly improved properties, which is desirable for automotive body manufacturing. The hybrid properties of such composites, however, remain largely unexplored and require thorough evaluation. This study investigates the mechanical performance of hybrid laminated composites fabricated from banana and woven glass fibers bonded with epoxy resin. The composites were produced using non-crimp banana (B) fiber and woven glass (WG) fiber fabrics through the hand lay-up process with four distinct stacking sequences: [WG/B-0⁰/B-0⁰/WG], [WG/B-0⁰/B-45⁰/WG], [WG/B-0⁰/B-60⁰/WG], and [WG/B-0⁰/B-90⁰/WG]. Comprehensive mechanical testing, including tensile, flexural, impact, and hardness tests, along with environmental testing (water diffusion) was conducted in accordance with ASTM standards. Results indicated that the [WG/B-0⁰/B-0⁰/WG] configuration exhibited the highest tensile strength, while the [WG/B-0⁰/B-60⁰/WG] configuration achieved superior flexural strength. The [WG/B-0⁰/B-45⁰/WG] configuration demonstrated the highest impact strength and energy absorption. Rockwell hardness testing revealed that the average hardness numbers for all orientations were approximately 79, which is considered moderate for composite materials. Water absorption tests showed maximum water saturation in [WG/B-0⁰/B-90⁰/WG] of ∼5.5%, where the other laminates had water saturation between 4.5-4.9%. The microscopic analysis of the [WG/B-0⁰/B-45⁰/WG] laminate suggests fiber-matrix debonding and fiber pull-out as the major cause of failure under tensile and flexural loading. These findings suggest that the hybrid laminated composites, particularly the [WG/B-0⁰/B-0⁰/WG] and [WG/B-0⁰/B-45⁰/WG] configurations, exhibit mechanical properties suitable for automotive body applications.

Evaluation of mechanically extracted banana fibers from pseudostem layers: A sustainable textile raw material

The separation of banana fibers from the pseudostem layers and the properties of two Thai banana cultivars, Musa acuminata (Kluai Hom) and Musa sapientum L. (Kluai Namwa) were investigated. The pseudostems were divided into three layers: outer (layer 1), middle (layer 2), and inner (layer 3). Fibers were extracted using a semi-automatic machine and subjected to chemical treatments. Results showed that layer 3 of Musa sapientum L. pseudostems yielded the highest amount of fibers with the lightest color. Fibers from layer 1 of Musa sapientum L. exhibited the highest tensile strength (606.90 g/denier) and elongation at break (9.54 %), higher than in all layers of Musa acuminata. SEM analysis revealed that chemically treated Musa acuminata fibers were less separated and broken than Musa sapientum L. fibers because the chemicals disrupted the lignocellulose bonds. Cross-sectional images showed larger lumens and more pronounced fiber group separation in Musa sapientum L. The outer layer of Musa sapientum L. pseudostem provided fibers with superior strength and elongation, demonstrating high potential as a sustainable raw material for the textile industry.

Influence of drying temperature on the properties of Colombian banana fibers for its potential use as reinforcement in composite materials

This study investigated the impact of drying temperature on the physicochemical and mechanical properties of banana pseudostem fibers sourced from the Cordoba region in Colombia. Banana fibers (BFs) were extracted through mechanical decortication from the banana pseudostem (BP) of the plant and subsequently oven-dried at temperatures of 40 °C and 90 °C. Six mathematical models were employed to analyze the drying behavior of the fibers. The density of the BFs was determined using the apparent density method, and their chemical composition was evaluated via bromatological analysis. Fiber diameter was measured using optical microscopy (OM). The BF samples were characterized by scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR), thermogravimetric analysis (TG), contact angle measurements, and tensile testing. The results indicated that noncellulosic materials were removed from the fibers when dried at 90 °C, as evidenced by alterations in thermal degradation and fiber surface morphology observed through TG and SEM, suggesting a reduction in lignin content. While drying temperature did not affect fiber stiffness or ductility, a correlation with fiber diameter was noted. Thinner fibers, ranging from 148 to 250 μm, exhibited increased tensile strength and Young’s modulus, attributed to a more compact microfibril arrangement.

The Effect of Adding Banana Fibers on the Physical and Mechanical Properties of Mortar for Paving Block Applications

Paving blocks might encounter diverse environmental conditions during their lifespan. The durability of paving blocks is determined by their capacity to endure various exposure conditions. Synthetic fibers have been used in mortar and concrete to improve their properties. This research investigates the influence of including banana fiber (BF) on the physical and mechanical characteristics of mortar. Five different mortar mixes were developed, with varying amounts of BF ranging from 0 to 2% by volume. Testing included ultrasonic pulse velocity, compressive strength, flexural strength, total water absorption, and sorptivity. Specimens were cured for up to 90 days. The results indicate that using 0.5% BF resulted in an improvement in compressive and flexural strength compared to the control mix. There was an increase in total water absorption and the water absorption coefficient in the presence of fibers. There appeared to be good correlations between the compressive strength and the other properties examined.

Achieving performance and functionality in PLA-based packaging: Insights from hybrid composites with false banana (Enset) fiber and ZnO nanoparticles

The use of poly(lactic acid) (PLA)-based composites reinforced with natural fibers is becoming increasingly popular in sustainable packaging. However, these materials often lack adequate barriers and desirable functional properties. Concurrently, zinc oxide nanoparticles (ZnO NPs) have been incorporated into PLA-based composites to develop functional packaging films. Despite this progress, there is a gap in the literature regarding packaging materials that require both functional and performance properties, specifically those that combine natural fibers and ZnO NPs within the PLA matrix. This study aims to develop and optimize the effects of ZnO nanofillers and false banana, also called Enset fibers (EFs) as hybrid reinforcements in PLA matrices. A central composite design (CCD) approach was used to evaluate the effects of EFs at three levels (5 %, 15 %, and 25 % w/w) and ZnO NPs at three levels (0 %, 5 %, and 10 % w/w) on the performance (tensile and flexural strength) and functional properties (water and antibacterial activity) of the resulting nanocomposite materials. The findings indicate that the inclusion of ZnO NPs significantly enhanced both the performance and functional properties of the nanocomposites, whereas the inclusion of EFs improved the performance properties but reduced the functional properties of the nanocomposites. Ultimately, this study identified an optimal formulation for producing durable and functional composites for various packaging applications.

Utilization of banana crop ligno-cellulosic waste for sustainable development of biomaterials and nanocomposites.

Banana (Musa spp.) is a tropical fruit cultivated in over 130 countries, producing significant lignocellulosic biomass. However, much of the agro-industrial waste from banana plants is neglected, contributing to environmental pollution. Around 60 % of the plant's biomass is generated after fruit harvesting, representing an untapped resource. This review examines the potential of banana plant waste for developing biocomposite and biodegradable materials. It covers the extraction and modification of banana fibers for composites, with a focus on the fabrication of nano biocomposites using banana fibers as reinforcement and polysaccharides or proteins as matrices. The review also evaluates the biodegradability and environmental impact of these materials through Life Cycle Assessment studies. Future research directions include refining processing methods, improving fiber-matrix compatibility, and enhancing the durability of banana fiber composites for packaging applications.

Mechanical properties of seaweed/banana fiber/hBN filled epoxy composites using Box–Behnken method

Natural particulate reinforced polymer (NPRP) composites are developed to replace synthetic fibers, aiming to reduce costs and environmental impact. Industries such as automotive, electronics, construction and aerospace are turning to filler-reinforced polymer composites and natural bio-fibers to enhance structural properties and develop eco-friendly products. This article presents research on epoxy-based composites fortified with natural and ceramic micro-sized fillers, including seaweed filler (SF), banana fiber (BF) and hexagonal boron nitride (hBN), fabricated using the hand layup technique. Through experiments, the effect of filler loading on the enhancement of mechanical properties such as tensile strength (TS), toughness (T), Young's modulus (YM), resilience (R) and yield strength (YS) of multiphase hybrid composites is investigated. Incorporating mixtures of ceramic filler and natural fillers into the epoxy matrix improves mechanical properties. The results demonstrated that the interlaced composites achieved optimum mechanical properties for S6 sample, including a TS of 24.85 MPa, T of 25.47 MJ/m3, YM of 7.15 GPa, R of 0.698 MJ/m3 and YS of 3.34 MPa. In comparison with S11 samples, the mechanical properties such as TS, T, YM, R and YS of the S6 composite sample are increased by 110.95%, 57.8%, 450%, 501.7% and 292.9%, respectively. The tensile fracture's scanning electron images reveal a homogenous surface with the formation of a fractured surface and defects. Statistical analysis at a 96% confidence level revealed the significance of the interaction between natural and ceramic micro particulate on the TS of the developed interlaced composite material, with a p-value of 0.007.

Damage and failure assessment of banana/ramie/epoxy composites using acoustic emission monitoring

In recent years, Composite materials that include natural fibers have played a significant role in aerospace, automotive industries, and other engineering applications. Due to its enhancing properties, the usage of composites has owing to an increase in day-to-day life. This research aims to develop a sustainable alternative material pronounced for environmental sustainability for surpassing synthetic fibers. Therefore, real-time monitoring and detection of the damage mechanisms in natural fiber composites are indispensable. In this regard, the acoustic emission (AE) technique lends itself to identifying the microscopic damage mechanisms in composite materials. Compression tests were performed in banana/ramie/epoxy composite specimens, and following consequences, the AE parameters (frequency, amplitude, counts, duration, energy rise time, etc.) were recorded. The novelty of this article is to detect the damage evolution and failure mechanisms of banana/ramie/epoxy composites under quasi-static compression with AE signal analysis for the first time. Findings showed that the stacking of hybrid reinforcing banana and ramie fiber improves the stress distribution, leading to enhanced load-carrying capacity (30.56 %), energy absorption (26.78 %), and stiffness (35.24 the compressive strength reached the maximum strength of the banana/ramie/epoxy composites%).This increase represents a substantial 30 % increase in AE energy absorption prior to failure, suggesting that the composite specimens experienced significant damage or extensive failure mechanisms Further, the AE parameters also showed that the AE energy under compression is relatively low and that frequency disperses between 70 and 150 kHz.

Amine-functionalized cellulose-silica composites for the remediation of hexavalent chromium (Cr IV) in contaminated water

Adsorption method for Hexavalent chromium (Cr(VI) removal from domestic and industrial wastewater is widely desirable due to public health concern of the heavy metal. The purpose of this study was to investigate the evaluation of Cr(VI) adsorption using a novel adsorbent: amine-functionalized cellulose-silica composite derived from banana fibers. We employed the in-situ sol–gel method to create cellulose-silica silane functionalized composites, analyzing them through different characterization techniques such as Attenuated total reflectance- Fourier transform infrared spectroscopy (ATR-FTIR), X-ray Diffraction Analysis (XRD), Thermo gravimetric analysis (TGA)/differential thermogravimetric (DTG), Brunauer–Emmett–Teller (BET), Scanning Electron Microscopy (SEM), and Transmission Electron Microscopy (TEM) techniques. ATR-FTIR depicted key organic constituents in raw banana pseudo stem fibers (BF) and the formation of SiO bonds in BCSiO2 composite, and further enhanced by the grafting of N-[3-(trimethoxysilyl)propyl ethylenediamine (DAPTMS) onto the BC-SiO2 surface in BC-SiO2-DAPTMS. XRD and TGA/DTG analyses revealed changes in crystallinity and thermal stability, while BET analysis showcased altered surface area and pore characteristics in BC-SiO2-DAPTMS (2 %). SEM and TEM imaging provided visual evidence of structural modifications and improved dispersion in BC-SiO2-DAPTMS composites. The impact of composite weight, contact time, and pH on Cr(VI) removal rates was examined, revealing optimal performance at slightly acidic pH 4 value (80.7 %) and enhanced efficiency with increased contact time of 65 min (86.66 %), composite weight of 1 g (82.62 %), and initial concentration was for 0.8 mg/l (80 %). The kinetics and isotherms analyzed using pseudo second order (PSO) and pseudo first order (PFO) models, highlight the composite’s efficiency. The Freundlich model was found to better fit the adsorption isotherm data, while the PSO model described the kinetics more accurately. These insights contribute to optimizing the BC-SiO2-DAPTMS (2 %) composite for efficient Cr(VI) ion removal in water treatment applications.

An analysis of diffusion mechanism and mechanical properties of jute, JUCO, and banana fiber composites in three different mediums

Natural fiber-reinforced polymer composites (NFRPC) are the most desirable for their low-cost, eco-friendly, and high-durability properties. Scientists are facing numerous challenges with this type of composite in a wet or high-humid environment. High water absorption and reduced mechanical properties are the main concerns for this type of composite. A new kind of fiber mat called JUCO, which is a mixture of jute and cotton, is introduced here. Banana fiber and jute yarn were used to fabricate unidirectional mats, which were made using a custom-designed handloom. The composite fabrication was done by hand layup with the cold press method. The tensile and flexural strengths decreased after immersion in three mediums (pH 3, pH 7, and pH 8) for 150 days due to the water aging effect. Minimum strength was found when the samples were immersed in pH 3 mediums. Tensile and flexural test results were also evaluated by the finite elemental method (FEM) to validate the experimental results. The main objectives of this study are to investigate the mechanical properties and degradation due to the aging of newly developed JUCO fiber-based composites.

The effect of nanocellulose and silica filler on the mechanical properties of natural fiber polymer matrix composites

Natural fiber-reinforced polymer matrix composites recently got great attention in biomedical applications due to their inherent characteristics such as biocompatibility, lightweight, and biodegradability. However, natural fiber composites suffer from poor mechanical properties and weak interfacial adhesion. It is well documented that the addition of nanofiller has improved the mechanical properties of different synthetic fibers such as glass and carbon composites. The main objective of this paper is to study nanofillers' effect on the mechanical properties of unidirectional false banana fibers reinforced polymer composites. The filler materials, crystalline nanocellulose fibrils, and crystalline nanosilica particles were extracted from sugarcane bagasse and its byproducts. The composite samples were fabricated by adding the nanofillers in unidirectional natural fibers arranged in four fiber orientations (0°, 0o/90o ±45o, and quasi-isotropic), and their tensile, flexural, compression strength, thermal stability, and void content were measured following ASTM standards. The results revealed that adding nanofillers increased the tensile, flexural, and compressive strengths by 16 % (98.83 Mpa), 11 % (161.60 Mpa), and 23 % (114.62 Mpa), respectively. Similarly, at 0° orientation, the addition of nanoparticles enhances the tensile, bending, and compressive modulus by 30 % (15.43 Gpa), 12 % (13.52 Gpa), and 60 % (42.6 Gpa), respectively. On the other hand, the void content was reduced with the addition of nanofillers. The results also revealed that composites with crystalline nanosilica particle fillers had superior thermal stability compared to crystalline nanocellulose fibril fillers. The overall results of this research give the confidence that nano particle-filled natural fiber composites can be used for bio-based engineering applications, such as prosthetic sockets.

The ongoing research focuses on exploring the potential of Careya arborea (CA) fiber, banana fiber (BF), and epoxy composites as sustainable alternatives to petroleum-based products and synthetic fibers. The aim is to enhance the interfacial bonding and overall performance of these composites while reducing reliance on traditional materials. The study investigates the adhesion between CA fiber, BF (both chemically treated), and epoxy with polylactic acid (PLA) coating. Specifically, it examined how the PLA coating affects the mechanical properties, including tensile strength, flexural strength, impact resistance, and water absorption behavior, of the fabricated composites. Mechanical characterizations of the composite specimens are conducted following ASTM standards. The PLA-coated and NaOH-treated specimens significantly improved their tensile strength (20.56%) and flexural strength (16.7%), and significantly reduced their water absorption capacity (by 47.6%) compared to the untreated ones. These findings highlight the promise of using treated natural fibers and PLA coatings to create more sustainable and high-performance composite materials.

A novel sensor-based digital instrument for assessment of quality of fibre extracted from banana pseudostem

Banana (Musa paradisiaca) farming generates huge quantities of biomass, all of which goes to waste due to the non-availability of suitable technology for its commercial application. The potential solution to this issue could be the conversion of pseudo-stems into valuable assets by converting them into fibres for various textile and non-textile applications. The specific characteristics of banana pseudo-stem fibre i.e. high absorptivity, breathability and biodegradability made it sustainable as well as suitable for the development of diversified products and blending with other natural fibres. However, non-uniformity in availability, obscurity of its intended uses and lack of knowledge for assessment of fibre quality posed a biggest hurdle to reach the fibre into the textile markets. Hence, a novel sensor-based digital instrument for assessing the quality parameters i.e. bundle strength and fineness along with overall grade of banana pseudo-stem fibre is presented in this research article. The developed instrument mainly consists of a fibre bundle strength measurement unit, fineness measuring unit and visual interface cum data acquisition unit. Test results indicated that bundle strength and fineness measured by developed instrument varied from 20.92 g/tex to 28.31 g/tex and 5.63 tex to 6.41 tex respectively. Furthermore, a good correlation between the measured and actual outputs of bundle strength (One-Way ANOVA, F28,2 = 3.914, P = 0.224), fineness (One-Way ANOVA, F51,2 = 4.730, P = 0.190) and overall quality of fibre (Independent sample T-Test, F34,1 = 0.95, P = 0.190). Was observed at 5 % level of significance. The present study also introduced a grading system for quality assessment of banana fibre based on the well-established and well-recognized grading system of jute fibre developed by Indian Standard (IS: 271 2020). The developed instrument is easy to build as well as easy to use and have an approximate cost of $1800.00. The combination of developed instrument and grading system is an accurate, feasible and time-ordered technique for the assessment of the overall quality of the banana fibre and well suited for the actual conditions.
