Abstract
The composite system studied in the present work consisted of a unidirectionally oriented cotton-fibre-reinforced polyester for which the mechanical properties had been completely characterized.
Friction and wear testing was performed on a pin-on-disc-type friction and wear machine in which the composite material formed the pins while stainless steel was used for the counter disc surface. The specimens used had five different values for the cotton fibre volume fraction with two different fibre diameters and three different directions of fibreing with respect to the sliding surface and direction. Two sliding speeds were used, above and below the pressure-velocity limit for unfilled polyester. Experimental results obtained for the friction coefficient and the wear rate in each case, as well as micrograph observations, are presented and discussed.
