Abstract
Sliding friction and wear behaviour of plain weave fabric reinforced poly(vinyl butyral) modified phenolic resin matrix composites made with three different reinforcing fabric materials, namely E-glass, high strength carbon and Kevlar-49, were investigated. Tests were performed on a pin-on-disc apparatus, and the specimens were slid against a cast iron disc under dry sliding conditions. The specific wear rate, coefficient of friction and operating wear mechanism, as evinced by scanning electron micrographs of the worn surfaces, changed with fabric material. Of the three reinforcing fabric materials, the composite made using glass fabric reinforcement exhibited poor wear resistance. Best wear resistance was observed in the Kevlar fabric reinforced composite. The wear mechanism was similar in all three composites.
