Exploring Hybrid Composite Tribological Behaviour: An Insight into Material Characteristics and PerformancePages 129-136
Abhinav Abstract:
Understanding the physio-technical characteristics of hybrid composites in terms of wear is essential for qualifying them for industrial tribological applications. A standard test according to ASTM G99 was performed on various types of laminated hybrid composites. Various synthetic fibers including e-glass, basalt, carbon, and aramid are blended with natural fibers such as jute (referred to as L1, L2, L3, and L4 respectively), and similarly, above synthetic fibers are also layered with hemp. The hybrid laminated composites were manufactured utilizing the hand lay-up method combined with vacuum bagging technique. Comparative studies were conducted under constant sliding distance and a 10 N load, with variable speeds set at 200, 300, and 400 rpm. The findings indicated that composites fabricated using hand layup and vacuum bagging techniques, particularly those of L3 and L4, exhibit reduced wear and specific wear rates. Reduced wear rate may be attributed to factors such as consistent fiber orientation, enhanced bonding observed in SEM analysis, optimal resin-to-fiber ratios, and decreased porosity. Also, the examination of wear mechanism and causative factors has been thoroughly explored, providing valuable insights for future investigations.
