ABSTRACT
Natural fibers are growing attention in the replacement of synthetic glass fiber due to their unique properties. The present work focuses on the wear properties of Epoxy with Cissus quadrangularis Stem Fiber (CQSF) particulate-filled red mud composite using Taguchi L9 orthogonal array technique. A three-body wear test rig is done with four input parameters and three levels such as velocities (0.75 m/s, 1.5 m/s and 2.25 m/s), sliding distances (400 m, 600 m and 800 m), applied loads (10 N, 20 N and 30 N) and red mud filler (0%, 5% and 10%) to observe the wear behavior of the developed composites. The level of impact on specific wear rate due to various input parameters such as velocity, distance, load and filler was computed. The hardness of the samples was increased by 10.7% for 5 wt.% red mud addition and 14.2% for 10 wt.% of red mud addition. The overall mean for the signal-to-noise (S/N) ratio of the specific wear rate of the specimen was found to be 34.62 dB, respectively. Finally, the experimental result and predicted theoretical result were validated after taking the conformation experiment. The wear mechanism of the composite materials after the abrasive wear test was substantiated using scanning electron microscope (SEM) analysis.
摘要
天然纤维由于其独特的性能, 在替代合成玻璃纤维方面受到越来越多的关注. 本文采用田口L9正交试验技术, 研究了环氧树脂与Cissus四边形干纤维 (CQSF) 颗粒填充赤泥复合材料的磨损性能. 三体磨损试验台采用四个输入参数和三个水平, 如速度 (0.75m/s, 1.5m/s和2.25m/s), 滑动距离 (400m, 600m和800m), 外加载荷 (10 N, 20 N和30 N) 和赤泥填料 (0%, 5%和10%), 以观察所开发复合材料的磨损行为. 计算了速度, 距离, 载荷和填料等输入参数对比磨损率的影响程度. 加入5% (质量分数) 赤泥的试样硬度提高了10.7%, 加入10% (质量分数) 赤泥的试样硬度提高了14.2%. 发现试样比磨损率的信噪比的总平均值分别为34.62 dB. 最后, 通过构象实验对实验结果和理论预测结果进行了验证. 通过扫描电子显微镜 (SEM) 分析, 证实了磨料磨损试验后复合材料的磨损机理.
