Characterization of carbon fiber-reinforced poly(phenylene sulfide) composites prepared with various compatibilizers

Abstract

The aim of this study was to investigate the effects of different compatibilizers on the properties of polyamide-sized carbon fiber-reinforced poly(phenylene sulfide) composites. The composites were prepared by using melt blending and injection molding methods by using three different compatibilizers at various loading levels. The characterization of composites was performed by Fourier transform infrared spectroscopy, tensile test, dynamic mechanical analysis, differential scanning thermometer, thermogravimetric analysis and scanning electron microscope. According to tensile test results, the highest increment in tensile strength and strain at break values of composites was observed with the addition of Joncryl. According to scanning electron microscope and dynamic mechanical analysis results, the best interfacial adhesion between carbon fiber and poly(phenylene sulfide) was obtained by using Joncryl as the compatibilizer.
