PREPARATION AND MECHANICAL PROPERTIES OF CF/PPS KNITTED COMPOSITES

Abstract

Abstract: CF/PPS was prepared by blending method,and continuous carbon fiber reinforced polyphenylene sulfide composite laminates were prepared by moulding process. The effects of layers, hot pressing temperature, hot pressing time, resin content and silane coupling agents on the mechanical properties of composite laminates were studied. Carbon fibers and composite laminates were characterized by universal material testing machine, scanning electron microscopy and SEM-EDS. The results show that the optimum technological conditions of carbon fiber reinforced polyphenylene sulfide composite laminates are as follows: the number of layers is 20, the hot pressing temperature is 330 ℃, the hot pressing time is 30 min, and the resin mass fraction is 50.2%. The mechanical properties of composite laminates are significantly improved after being treated with silane coupling agent KH560, and their tensile strength and flexural strength are 920.1 MPa and 890.6 MPa, respectively.

Key words: polyphenylene sulfide, thermoplastic composites, mixed weave fabric, silane coupling agent
