“…This shows that as the fiber loading increases, the tensile strength decreases in the epoxy composites subjected to the optimization at 10% fiber loading, which gives the maximum tensile strength. 55 The effect of fiber loading on flexural strength is also shown in the figure, which is also having the similar trend except that the flexural strength at 10% fiber loading that shows an increment of around 6% from pure epoxy composite. The main cause of this trend could be poor interaction and wetting of the untreated PALF with the epoxy resin matrix.…”

The progress in the development of composites with natural fibers for various applications in different sectors witnesses remarkable success worldwide in the last decade. Among the various natural fibers existing worldwide, pineapple leaf fibers (PALFs) possess remarkable mechanical properties because of the maximum content of cellulose (*80%) among all natural fibers. In spite of having few limitations such as hydrophilicity, its advantages such as low cost, low weight, and biodegradability overweigh their limitations. The PALFs are poorly reported in the literature as a reinforcement in epoxy material. Bagasse, wheat straw, and coir have been successfully reinforced with epoxy resin; but inspite of having highest tensile strength among all natural fibers, PALF's are seldom used. PALF has been characterized chemically, morphologically, and thermally. Using thermal analysis, the models were fitted to calculate its activation energies at different fraction levels using different heating rates. PALF epoxy composites have been prepared using the hand layup method. The effect of fiber loading has also been studied for morphological, chemical, mechanical, and thermal properties of composites. Composites with 10% fiber loading have better mechanical properties in comparison to composites with other fiber loading. Scanning electron microscopic micrographs of fractured surfaces have been analyzed for all fiber loading composites, and the results have been successfully studied linking the stated work of other distinguished researchers of this arena.

“…The mixture was poured into the mold having a size of 300 × 300 × 10 mm 3 and cured for 24 hr at ambient temperature. All composite material is manufactured by the Hand layup technique . To avoid the problem of sticking of composite material, the mold has been coated with Teflon sheet, and formation of bubble may create the problem.…”

This study is to investigate the mechanical, thermal, and water absorption properties of wheat straw and bagasse fiber-reinforced epoxy blended composites. To enhance these properties, wheat straw fiber was blended with bagasse fiber. The wheat straw and bagasse fibers were prepared with various weight ratios (80/20, 60/40, 40/60, and 20/80) and then incorporated into the epoxy matrix by molding technique to form composites. The mechanical, thermal, and water absorption characteristics were examined using blended composite samples. In this research, it has been observed that increases in the bagasse fiber content in wheat straw/epoxy composites result in superior the mechanical, thermal, and decreasing the moisture absorption property. A scanning electron microscope was used to observe the fracture surface of the samples. K E Y W O R D Sbagasse fiber, mechanical properties, SEM, thermal properties, wheat straw fiber

“…Composites based on epoxy treated fibers showed low water absorption of 1.58 % in comparison with the untreated fibers composites (2.79-6.09 %). Similarly, epoxy-based composites fabricated by using treated bagasse (1 % NaOH and 1 % acrylic acid) represented 8 % water absorption in comparison with untreated fibers composites (12 %) [177]. Composites formed by using jute fibers treated with pristine and NaOH followed by impregnation of MAPP (5 wt %) and maleic anhydride PE (MAPE) (5 wt %) showed the reduction in water uptake ability.…”

Advancement in science and technology provides the significant opportunities to utilize the plant fibers (unnoticed materials), which are cheap, abundant, sustainable, and biodegradable. A combination of polymer with the untreated and treated fibers, extracted from lignocellulosic biomass, has been getting significant attention because of their low cost, ecofriendly nature, and enhanced mechanical performance. This article delivers an explicit overview of the plant fibers, extraction and pretreatment of the plant fibers, development of the plant fibers reinforced polymeric composites, and the mechanical properties associated with these biocomposites. A special focus is concentrated on the pretreatment of hydrophilic plant fibers for better compatibility with the polymers, to obtain the enhanced composites having desirable properties. Finally, the effects of several pretreatments on the tensile and water absorption properties of the plant fibers reinforced composites has been included in detail for the better understanding of their practical applications.
