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