Determining the resistance to abrasion of the flexible cladding for armours and automobile structural components with the aid of lab scale tests has become increasingly important. In the present study, three body wear behaviour of flexible green composites comprising of jute in woven fabric form with interleaved natural rubber sheets bonded through rubberized B stage cured Pre pegs have been studied. Flexible composites are fabricated in three different configurations having different layers of jute and rubber. The present study makes use of silica sand as the abrasive medium. The specific wear rate along with loss in mass and volume of the composite due to wear is determined and it was found that specific wear rate is dependant of the sliding distance. Comparing the specific wear rate of all the three stacking sequences, it was found that JRJ stacking sequence provides better wear resistance. Compliant and tough nature of the rubber makes it hard to wear it out through tearing action and also the wear resistance of flexible composites is enhanced with inclusion of rubber. Mechanism of wear in each of the constituent used is studied. The present study serves as a benchmark work for the future research in this area.

新型黄麻/天然橡胶柔性绿色复合材料的三体磨料磨损评估

借助于实验室规模的测试来确定用于铠装和汽车结构部件的柔性覆层的耐磨性变得越来越重要。在本研究中,已经研究了由黄麻制成的柔韧的绿色复合材料在机织织物中的三种人体磨损行为,该织物与通过橡胶化的B级固化的预钉粘合而成的交错天然橡胶片材在一起。柔性复合材料以三种不同的结构制成,具有不同的黄麻和橡胶层。本研究利用硅砂作为研磨介质。确定了特定的磨损率以及由于磨损引起的复合材料的质量和体积损失,并且发现特定的磨损率取决于滑动距离。比较所有三个堆叠顺序的特定磨损率,发现JRJ堆叠顺序提供了更好的耐磨性。橡胶的柔韧性和坚韧性使其很难通过撕裂作用将其磨损,并且通过添加橡胶可以增强柔性复合材料的耐磨性。研究了所用每种成分的磨损机理。本研究作为该领域未来研究的基准工作。
