Friction behaviors of staple carbon fiber composites

Abstract

This study aims to examine the frictional behavior of staple carbon fiber composites (sCFCs). The staple carbon fiber reinforced polycarbonate (PC) composites were prepared by film stacking for two different impregnation levels. Mechanical properties such as tensile and flexural strengths and moduli and static/dynamic friction coefficient (COF) were determined. The COF and temperature as a function of wearing cycles for sCFCs subjected to different applied pressures were also determined by a disk-on-disk sliding wear test machine. The less impregnated sample exhibited superior tribological performance owing to its rough surface and low frictional heat generation.
