Abstract

The influence of annealing on the morphology and the performance of randomly oriented short glass fiber-reinforced polyphenylene sulfide (PPS) composites have been investigated by differential scanning calorimetry (DSC), dynamic mechanical analysis (DMTA), impact tests, and scanning electron microscopy (SEM). Endotherms belonging to secondary crystals are seen 10-20 degreesC above the annealing temperatures. DMTA results showed that the annealed samples had higher glass transition temperatures and elastic moduli values when compared with the quenched samples. The effect of microstructure on elastic deformation, crack formation, and crack propagation are studied with instrumented impact tester.
