Polyphenylene Sulfide (PPS) is an engineering thermoplastic which is used widely due to its good dimensional stability and high-temperature resistance to chemical. Short glass fibers (SGFs) and pitch-based short carbon fibers (SCFs) are attractive reinforcements on thermoplastics because of economical and mechanical, thermal properties. In this study, hybrid fillers composed of surface treated SCFs and SGFs are used for increasing thermal conductivity and mechanical properties of PPS. For expression properties of carbon fiber, defect and acidic functional groups are introduced on the surface. Base on the same principle, silane coupling agent also introduced on the surface of glass fiber and both lead to adhesion to surface treated SCFs and SGFs. The results of introduced functional groups, chemical interactions, thermal conductivity, thermal degradation temperature, thermal effects and mechanical properties were investigated by FT-IR, C-therm TCi, TGA, DSC, SEM and UTM. |
