The role of synthetic and natural fillers on three-body abrasive wear behaviour of glass fabric-epoxy hybrid composites

摘要

Polymer matrix composites are a promising candidate in tribological applications due to possibility of tailoring their properties with special fillers. The comparative performance of Glass-Epoxy (G-E) composites with influence of synthetic fillers such as graphite (Gr) and silicon carbide (SiC) and biobased natural filler jatropha oil cake (JOC) was experimentally investigated. All the composites were fabricated using vacuum-assisted resin infusion (VARI) technique. The mechanical properties were studied in accordance with ASTM standards. The three-body abrasive wear studies were carried out with rubber wheel abrasion tester as per ASTM-G65 standard. Two different loads namely 22 N and 32 N with different abrading distances viz, 135, 270, 405, and 540 m are test parameters. The results reveal that addition of JOC in G-E composites has significant influence on wear under varied abrading distance/load. Further, it was found that SiC filled G-E composites exhibited better wear resistance compared to Gr/JOC filled G-E composites. The operating wear mechanisms have been studied by using scanning electron microscopy.
