Nowadays, the demand for needle-punched nonwoven fabrics has been increasing, especially in the areas of high-performance composites as reinforcement due to their potential of imparting high [Formula: see text]-directional strength, easy resin absorption, light weight, and low cost. In this study, needle-punched nonwoven viscose fabric-reinforced epoxy composites are prepared by varying the area density of fabric mat (100[Formula: see text]gsm, 200[Formula: see text]gsm, 300[Formula: see text]gsm, and 400[Formula: see text]gsm) at constant fabric loading of 30[Formula: see text]wt.%. The effects of area density on mechanical and slurry abrasion behavior of composites are studied under controlled laboratory conditions. It is observed that the mechanical properties and abrasive wear resistance under steady-state condition has been improved with the increase in area density of fabric mat. Furthermore, experimental design through Taguchi’s L[Formula: see text] orthogonal array is applied to find out the optimal parametric combination for minimum wear rate. It is also observed through the analysis that silica sand size and sliding velocity are the most influential factors for wear rate.

采用 DOE 方法对无纺粘胶纤维复合材料浆料磨损行为的摩擦学研究

如今，针刺非织造布的需求不断增加，特别是在作为增强材料的高性能复合材料领域，因为它们具有赋予高[公式：见正文]方向强度、易于树脂吸收、重量轻和低成本。在这项研究中，通过改变织物垫的面积密度（100[公式：见文]gsm，200[公式：见文]gsm，300[公式：见文] gsm 和 400 [公式：见文本]gsm）在 30 [公式：见文本]wt.% 的恒定织物负载下。在受控的实验室条件下研究了面积密度对复合材料的机械和浆料磨损行为的影响。观察到，随着织物毡面密度的增加，稳态条件下的力学性能和耐磨性得到改善。此外，通过田口的 L[公式：见文本] 正交阵列的实验设计被应用于找出最小磨损率的最佳参数组合。通过分析还观察到，硅砂尺寸和滑动速度是影响磨损率的最重要因素。
