In this research, a new class of composite made up of wood apple dust (WAD) and epoxy is developed using the hand lay-up process. The impact of WAD filler on the physical and wear characteristics of epoxy-based composites are examined. The composite samples are prepared by varying the weight content of WAD (0, 3, 6, 9, and 12 wt%). The composites are subjected to dry sliding wear testing in accordance with the L₂₅ Taguchi design to calculate the specific wear rate (SWR). An optimum parametric combination of control factors is established for the composites to have the least amount of wear loss. The SWR of WAD/epoxy composites is also predicted using commercial finite element method (FEM) software ANSYS 2019 R2. The experimental findings are compared with the predicted wear rates of the composites. The results revealed that addition of WAD powder improved the wear resistance of the composites. A remarkable increase in tensile, compressive and flexural strength values of 34.79%, 10.12%, and 22.66% respectively, is observed. Neat polymer has tensile, compressive and flexural strengths of 48, 82, and 22.5 MPa respectively, and the values increased to 64.7, 90.3, and 27.6 MPa with addition of 12 wt% WAD. It is further observed that out of the four control factors the most influencing control factor affecting the wear rate of the composites in decreasing order are WAD content, sliding velocity, sliding distance, and normal load.

采用田口分析和有限元法表征木苹果粉填充环氧复合材料的滑动磨损

在这项研究中，采用手糊工艺开发了一种由木苹果粉（WAD）和环氧树脂组成的新型复合材料。研究了 WAD 填料对环氧基复合材料的物理和磨损特性的影响。通过改变 WAD 的重量含量（0、3、6、9 和 12 wt%）来制备复合材料样品。根据 L ₂₅ Taguchi 设计对复合材料进行干滑动磨损测试，以计算比磨损率 (SWR)。建立了控制因素的最佳参数组合，以使复合材料具有最少的磨损量。还使用商业有限元法 (FEM) 软件 ANSYS 2019 R2 预测了 WAD/环氧树脂复合材料的 SWR。将实验结果与复合材料的预测磨损率进行比较。结果表明，WAD粉末的添加提高了复合材料的耐磨性。观察到拉伸、压缩和弯曲强度值显着增加，分别为 34.79%、10.12% 和 22.66%。纯聚合物的拉伸强度、压缩强度和弯曲强度分别为 48、82 和 22.5 MPa，添加 12 wt% WAD 后，这些值分别增加到 64.7、90.3 和 27.6 MPa。进一步观察到，在四个控制因素中，对复合材料磨损率影响最大的控制因素按降序排列是WAD含量、滑动速度、滑动距离和法向载荷。
