The main objective of the current experimental work is to determine the mechanical properties of borassus fruit fiber (BFF)-based composites and compare the mechanical performance of composites fabricated with different chemically treated BFF. The BFF was treated with (a) sodium hydroxide (NaOH), (b) benzoyl chloride (C₆H₅COCL), and (c) acetyl chloride (CH₃COCL) and compared the surface morphology of the BFF with the assistance of SEM (scanning electron microscope) and FTIR (Fourier-transform infrared spectroscopy). The mechanical properties such as (a) tensile, (b) flexural, (c) hardness, (d) impact, and (e) water absorption behavior of the treated and untreated BFF-based composites are evaluated. The experimental findings infer that the mechanical properties of the BFF-based composites are better than the neat epoxy chosen for the purpose of investigation. The chemically treated BFF-based composites are found to have enhanced mechanical properties and reduced water absorption tendency than that of the untreated BFF-based composites. SEM examination shows that the acetylation treated BFF-based composites has the more surface roughness and thus the excellent mechanical properties and less water absorption tendency among all the chemically treated and untreated BFF-based composites.

表面改性对含硼水果纤维复合材料性能的影响

当前实验工作的主要目的是确定基于牛ras果实纤维（BFF）的复合材料的机械性能，并比较采用不同化学处理过的BFF制造的复合材料的机械性能。用（a）氢氧化钠（NaOH），（b）苯甲酰氯（C ₆ H ₅ COCL）和（c）乙酰氯（CH ₃）处理BFFCOCL），并借助SEM（扫描电子显微镜）和FTIR（傅里叶变换红外光谱）对BFF的表面形态进行了比较。评估了处理过的和未处理过的BFF基复合材料的机械性能，例如（a）拉伸，（b）弯曲，（c）硬度，（d）冲击和（e）吸水性能。实验结果表明，BFF基复合材料的机械性能优于为研究目的而选择的纯环氧树脂。发现化学处理的基于BFF的复合材料比未处理的基于BFF的复合材料具有增强的机械性能和降低的吸水趋势。
