Horsehair-based composites have been prepared by reinforcing polylactic acid (PLA) using hot compression molding. The weight fraction of horsehair fibre in composites has been varied from 0% to 30 wt.% to investigate the effect of fibre loading on the mechanical properties and moisture absorption performance of the developed composites. The mechanical properties, such as strength and modulus (tensile and flexural), impact energy, and moisture absorption behaviour of the fabricated composites, are experimentally evaluated. The experimental results recommend that the composites reinforced with 20 wt.% horsehair exhibit superior mechanical properties as compared to other developed composites. The tensile strength and modulus, flexural strength and modulus, Charpy and Izod impact energy of the composites reinforced with 20 wt.% horsehair are improved by 9.52, 28.74, 7, 5.63, 398.11 and 379.31% as compared to, one-on-one, neat PLA. The findings also reveal that the percentage of moisture absorption of the developed composites increases with an increase in the fibre content in the developed composites.

动物纤维基复合材料的机械表征
通过使用热压成型增强聚乳酸(PLA),可以制备基于马海毛的复合材料。马海毛纤维在复合材料中的重量分数已从0%更改为30 wt。%,以研究纤维负载对开发的复合材料的机械性能和吸湿性能的影响。通过实验评估了机械性能,如强度和模量(拉伸和弯曲),冲击能和吸湿性能。实验结果表明,与其他已开发的复合材料相比,用20 wt。%的马毛增强的复合材料表现出优异的机械性能。用20 wt。%的复合材料增强的复合材料的拉伸强度和模量,挠曲强度和模量,夏比和艾佐德冲击能。与一对一的纯PLA相比,马毛百分比提高了9.52、28.74、7、5.63、398.11和379.31%。研究结果还表明,开发的复合材料的吸湿率随开发的复合材料中纤维含量的增加而增加。
