ABSTRACT
Natural fibers have the potential to replace artificial fibers in structural applications. The abrasive wear performance of natural fiber–reinforced polymer composite has not been investigated in many studies. This study discusses the specific wear rate of Cissus quadrangularis stem fiber (CQSF)/epoxy with coconut shell ash (CSA) composite using a three-body rubber wheel wear test rig. The results were analyzed by using Taguchi L9 orthogonal array. The input parameters are velocities (0.75, 1.5, and 2.25 m/s), abrading distances (400, 600, and 800 m), applied loads (10, 20, and 30 N) and CSA filler (0, 5, and 10 wt.%), and the output response is specific wear rate. The average mean signal-to-noise (S/N) ratio under ‘lower-the-best’ condition for specific wear rate is 35.54 dB. The filler addition significantly reduced the specific wear rate at 5 wt.% of CSA addition. The influence of filler on specific wear rate is higher than other input parameters followed by load, abrasive distance, and velocity. The experimental and predicted values of the specific wear rate for the optimum input parameters were 5.36 10–3 and 5.17
10–3 mm3/Nm. The worn surfaces were examined with the help of scanning electron microscope (SEM) images.
摘要
天然纤维在结构应用中有可能取代人造纤维. 天然纤维增强聚合物复合材料的粒磨损性能在许多研究中尚未得到研究. 本研究使用三体橡胶轮磨损试验台, 讨论了Cissus四边形茎纤维 (CQSF)/环氧树脂与椰壳灰 (CSA) 复合材料的比磨损率. 结果用田口L9正交表进行分析. 输入参数为速度 (0.75, 1.5和2.25m/s), 磨损距离 (400, 600和800m), 施加载荷 (10, 20和30 N) 和CSA填料 (0, 5和10 wt.%), 输出响应为特定磨损率. 在 “低于最佳” 条件下, 比磨损率的平均信噪比 (S/N) 为35.54 dB。在CSA添加量为5 wt.%时, 填料添加量显著降低了比磨损率. 填料对比磨损率的影响大于其他输入参数, 其次是载荷, 磨粒距离和速度. 最佳输入参数下的比磨损率实验值和预测值为5.36×10−3和5.17×10−3 mm3/Nm. 借助扫描电子显微镜 (SEM) 图像检查磨损表面
