Abstract

This study investigates the sliding wear characteristics of wood ash-based banana/walnut reinforced epoxy composites using the hand layup technique. This research investigates the impact of wood ash on composites to obtain excellent wear resistance and moderate mechanical properties, which can be utilised in various engineering applications. As the percentage of wood ash increases in the composites, the tensile strength and hardness of the composites increase, but the impact energy declines marginally. The sliding wear test is carried out on a dry sliding wear test machine (pin-on-disc). The Grey-Taguchi method and optimal factor settings are used to evaluate the multiple responses of composites. The results showed that the most critical factor influencing the properties of composites is wood ash content (41%), accompanied by sliding velocity (35%), and lastly, the normal load (24%). Scanning electron microscopy was used to analyse the composites' worn surfaces to investigate the potential wear mechanism.
木灰对香蕉/核桃基环氧复合材料力学和滑动磨损性能的协同作用及灰色关联分析优化
采用手工铺层技术研究了木灰基香蕉/核桃增强环氧复合材料的滑动磨损特性。本研究探讨了木灰对复合材料的影响,以获得优异的耐磨性和适度的机械性能,可用于各种工程应用。随着木灰含量的增加,复合材料的抗拉强度和硬度增加,但冲击能略有下降。滑动磨损试验在干式滑动磨损试验机(销盘式)上进行。采用灰色田口法和最优因子设置对复合材料的多重响应进行评价。结果表明:影响复合材料性能的最关键因素是木灰分含量(41%),其次是滑动速度(35%),最后是正常载荷(24%)。利用扫描电子显微镜对复合材料的磨损表面进行了分析,探讨了潜在的磨损机理。
