In this study, it was aimed to investigate the mechanical, thermal, thermomechanical, and morphological properties of pumice and calcium carbonate (CaCO3)-filled poly(phenylene sulfide) (PPS) composites and compare the effect of these filler materials on the properties of composites. Mechanical test results indicate that %1 pumice and CaCO3 addition increased the tensile strength value of PPS. With the %1 loading level of pumice, tensile strain of composites remained unchanged, but for other loading levels of both fillers, tensile strain of composites decreased. Hardness of composites increased with the addition of pumice to PPS matrix for all loading levels of pumice. The lowest damping factor peak intensity was observed for %1 pumice included composites. Morphological analyses results revealed that pumice particles are clearly embedded in the PPS matrix and covered with matrix. On the other hand, there are a number of microvioids that can be observed in the tensile fracture surfaces of CaCO3-filled composites. (C) 2015 Society of Plastics Engineers
