Effects of polyarylene sulfide sulfone on the mechanical properties of glass fiber cloth-reinforced polyphenylene sulfide composites

In this article, polyphenylene sulfide (PPS)/polyarylene sulfide sulfone (PASS) was melt blended and PPS/PASS/glass fiber cloth (GFC) composite was prepared. Mechanical testing and dynamic mechanical analysis DMAof PPS/PASS blends and PPS/PASS/GFC composites were performed to inspect the effects of PASS on the mechanical properties of the composites. With the presence of PASS, the strength and modulus of the PPS/PASS blends declined to some extent, while the strength and modulus of the PPS/PASS/GFC composites increased. The results indicate that the addition of PASS is beneficial for strengthening the interaction between PPS and GFC. The scanning electron microscopy results of the impact fracture surfaces of composites were also consistent with the data of mechanical properties.
