Natural fiber composites are increasingly gaining popularity as a cost-effective and environmentally friendly alternative to synthetic fibers. Incorporating a variety of fibers enhances mechanical properties. The arrangement of fibers plays a crucial role in determining the mechanical characteristics of laminate composites. Therefore, the primary objective of this study is to investigate how the stacking order of jute (J) and banana (B) fibers affects the mechanical behavior of composites made from phenolic resins. Four different fiber mat stacking sequences (J/B/B/J, B/J/J/B, J/B/J/B, and J/J/B/B) were used for developing the eco-fiber composites using the heat-press technique. Several mechanical parameters were assessed, including tensile strength, flexural strength, impact strength, and inter-laminar shear strength (ILSS).The experimental results indicated that the JBBJ composite exhibits superior tensile strength (46.65 MPa) and modulus (993 MPa) compared to the other composites due to the presence of high-strength jute fibers on the surface. Additionally, the flexural strength of the JBBJ composite (87.24 MPa) was found to be noteworthy. It was observed that the impact strength of jute fibers surpasses that of banana fibers. Consequently, the JBBJ composite demonstrates higher values for energy absorption (0.482 J) and impact strength (120 J/m) compared to the other composites tested. Moreover, the JBBJ composite displays higher inter-laminar shear strength and hardness values compared to BJJB, JBJB, and JJBB by 30%, 35%, and 43%, respectively. Scanning electron microscope microphotographs reveal strong correlational fracture failure mechanisms, indicative of improved mechanical properties in the JBBJ composite. Based on the experimental results, it is evident that the JBBJ composite can be utilized in lightweight applications.

“…The study reveals that enhanced mechanical properties were obtained with a composite sample with 40 vol.% fibre loading and 15 mm fibre length [26]. The effects of Parthenium hysterophorus and Impomea pescaprae fibres stacking sequences reinforced with epoxy were investigated by Raghunathan et al [27]. The findings of the tests show that composites comprising upper layers of Impomea pes-caprae fibres and a core layer of Parthenium hysterophorus fibres had improved mechanical properties and lower water absorption.…”

In the current investigation, the mechanical properties of epoxy composites reinforced with banana pseudostem fibres, specifically focusing on tensile and impact behaviour, are investigated. The manufacturing process employed the meticulous hand-lay-up technique to fabricate six distinct samples. These samples included various combinations of short and woven banana fibres, treated and untreated, as well as a hybrid configuration involving layers of woven and short fibres. A fixed weight ratio of 60% fibres to 40% epoxy matrix was maintained for consistency. To ensure optimal material integrity, a careful application of resin and hardener in a 10 : 1 weight ratio was layered, with each addition of fibre followed by thorough rolling to eliminate any potential bubbles. The density and void fraction of the resulting composites were meticulously assessed to gauge the influence of this layering approach. Additionally, an X-ray diffraction (XRD) analysis was conducted to ascertain the impact of the chemical treatment on the cellulose content of the fibres. Our findings revealed that the tensile and impact properties were notably superior in the woven fibre composites. In particular, the chemically treated woven banana fibre epoxy composite displayed impressive values of 64.95 MPa for tensile strength and 24.37 KJ/m2 for impact strength. To gain deeper insights into the structure-property relationship, test specimens were analyzed using scanning electron micrographs. Lastly, comparative analysis by mapping the tensile properties from our present work with those from existing studies was carried out.

“…Furthermore, voids occur as a result of the limited space and time available for the matrix to disperse and fill the interface space between fibers under this condition. [ 82 ] Figure 10B showed the presence of fiber breakage, fiber pullout, and matrix failures. Using SEM fractography, it is possible to clearly see the debonding and fiber/matrix interfacial gaps, which confirms the need for further surface modification of the cellulosic fibers in question.…”

This research investigated the scope of using a fiber harvested from Mucuna atropurpurea (MAF) plant as reinforcement in fiber-reinforced plastics. An optical microscope and a pycnometer were used to calculate the diameter (289 ± 21 μm) and density (1082 ± 29 kg/m 3 ) of the MAF. Using chemical compositional analysis, 58.74 ± 5.74 wt% cellulose and 16.31 ± 3.21 wt% hemicellulose, and 14.22 ± 3.36 wt% lignin and 0.38 ± 0.08 wt% wax components were found in the MAF. Numerous chemical stretching in the MAF were checked using Fourier transform infrared spectroscopy. Briodo analysis (68.08 kJ/mol) showed the kinetic activation energy of the MAF. Surface morphological inspections suggested surface treatments of MAF due to contaminations and wax on the fiber surface. The statistical analysis conducted for determining the tensile properties of MAF revealed that MAF is a suitable candidate to produce fiber-reinforced plastics. Characterization of MAF-reinforced polyester composites showed that 40 mm fiber length and 30 wt% fiber enhanced tensile strength (109.51 ± 2.1 MPa), flexural strength (156.62 ± 3.1 MPa), and hardness (94 ± 4 HRRW). Fractography images of composites with fiber pull-outs in the MAF-reinforced plastics were taken for analysis. Less cavities and voids in the 30 wt% MAF-reinforced composites were found along with reduced water absorption.
