THE MECHANICAL PROPERTIES AND FRACTURE MORPHOLOGIES OF CARBON FIBER REINFORCED POLYSULFONE COMPOSITES

In this paper, the effects of carhou contents and distrilmtion form on the mechanical, thermal,wear proporrties and fracture motphologies of polysnlfoue (PSF) composites have been studied.With increasing of short-CF content,the imapct strength of PSF slightly dec reases,but tensile and flexible strength increase.In the long-CF/PSF composite system these strengths increase a more prononncedlr than in short-CF/PSF composite.The interlaminar shear strength of long-CF/PSF composite is about 80% of tensile strength of PSF. CF/PSF composites have much better wear yroperties and higher thermal deformation temperature with increasinh of carbon fiber contents.Failure in CF/PSF composite appears in form of dehonding between fiber and resin.
