Himalayan Natural Fiber-Reinforced Epoxy Composites: Effect of Grewia optiva/Bauhinia Vahlii Fibers on Physico-mechanical and Dry Sliding Wear Behavior

ABSTRACT

The physical, mechanical, and sliding wear properties of Grewia optiva and hybrid G. optiva/Bauhinia vahlii fiber-reinforced epoxy composites were investigated. Results reveal that 6 wt.% hybrid G. optiva/B. vahlii fiber-added composites resulted in highest physical (void content, water absorption) and mechanical (impact energy, hardness, tensile, and flexural strength) properties. An L₂₇ orthogonal array of Taguchi method was implemented to extract the optimal level of control factors. The optimal combination of control factors for achieving lowest wear rate was obtained as 4 wt.% fiber content, 2.5 m/s sliding velocity, 15 N normal load and 2000 m sliding distance.

摘要

研究了Grewia-optiva和混合Grewia-optiva/Bauhinia-Vahlii纤维增强环氧树脂复合材料的物理、力学和滑动磨损性能. 结果表明，6 wt.%混合Grewia-optiva/Bauhinia-Vahlii纤维添加复合材料的物理（空隙率、吸水率）和机械（冲击能、硬度、拉伸和弯曲强度）性能最高. 采用田口法L27正交数组提取最优控制因子. 以4 wt.%的纤维含量、2.5 m/s的滑动速度、15 N的正常载荷和2000 m的滑动距离为控制因素，得到了达到最低磨损率的最佳组合.
