Performance of unidirectional carbon fibre cloth/carbon composite laminates fabricated by hot-pressing
摘要
Abstract
Unidirectional carbon fibre cloth/carbon composite laminates were fabricated by hot-pressing alternating stacks of unidirectional carbon fibre cloth and uniformly-spread powder mixtures of phenolic-resin coated nature graphite flakes and pitch. The effects of the contents of carbon fibre cloth on the density, porosity, flexur-al strength, friction and wear properties of the composite laminates were investigated by SEM, a friction-and-wear testing machine and a universal testing machine. Results showed that the sample with the best overall performance had a mass fraction of carbon fibre cloth of 50% . This material had a flexural strength of 112.2 Mpa, a density of 1.72g/cm3, a friction coefficient of 0.28, and a wear rate of 3.68×l0-13 m3·N-1. Failure behavior was pseudoplastic and there were a large number of fibre pullouts on the fracture surface. An increase of graphite content was favorable for the formation of a film during wear, which reduced the wear rate and resulted in a steady value of the coefficient of friction.关键词
