The focus of this work was the possibility to expand the use of coir fibers, as byproduct of the coconut industry by turning them into new eco-composites. The evaluation of coir fiber-reinforced composites focuses on the chemical treatment and processability of the coir fiber, how well it interfaces with a phenolic resin as Bakelite, and an analysis of how the mechanical properties of the final product change when adding treated coir fibers. The results show that the flexural stress value of composite shows a stabilization and the ductile behavior of composites was improved around 34.45% as compared to the neat Bakelite matrix. However, dynamic mechanical analysis showed a change in the rheological properties of the biocomposites with increasing temperature and fiber loading; the increase of temperature tends to enhance the free volume of the system and thereby decreases the fibers-matrix adhesion surface leading to decrease the complex modulus. This study represents a new opportunity to valorize biomass residues into green materials, which could reduce domestic dependence on petroleum-based thermoplastics.

这项工作的重点是通过将椰壳纤维转变为新的生态复合材料来扩大椰纤维作为椰子产业副产品的用途。椰壳纤维增强复合材料的评估重点在于椰壳纤维的化学处理和可加工性，与酚醛树脂（如电木）的交接程度以及对加入经处理椰壳纤维后最终产品的机械性能如何变化的分析。结果表明，与纯胶木基体相比，复合材料的弯曲应力值稳定，复合材料的延性提高了34.45％。但是，动态力学分析表明，随着温度和纤维含量的增加，生物复合材料的流变特性也发生了变化。温度的升高往往会增加系统的自由体积，从而降低纤维与基质的粘合表面，从而降低复数模量。这项研究为将生物质残留物评估为绿色材料提供了新的机会，这可以减少国内对石油基热塑性塑料的依赖。
