Fatigue resistance of carbono fiber/polyphenylene sulfide composites engineered for automotive use

Abstract: This study comprehensively investigates a carbon fiber-reinforced polyphenylene sulfide (CF/PPS) composite through tensile, fatigue, interlaminar shear strength (ILSS), dynamic mechanical tests (DMA), and also fractographic analysis. Prepared via hot compression molding, the CF/PPS composites exhibit a consistent quality. Tensile tests show an elastic modulus of 37.2 ± 0.2 GPa Leia mais…
