The effect of pressure-induced flow (PIF) processing on the mechanical properties of non-continuous carbon fiber (CF) reinforced polyphenylene sulfide (PPS) composites was investigated. A series of CF/PPS composites under different processing conditions were prepared through PIF-processing. SEM observations showed that the interfaces adhesion between CFs and PPS became stronger and ductile fracture mainly occurred in PPS matrix. This brought to a great increase of both strength and toughness by about 2 folds, when the composites were processed at 240 degrees C and under 263 MPa. The results in differential scanning calorimetry (DSC) and X-ray diffraction (XRD) measurements indicated more regular crystalline structures and orientation of lamellae formed during PIF-processing.
