利用扫描电子显微镜（ＳＥＭ）观察了短碳纤维增强聚芳醚酮复合材料（ＳＣＦ／ ＰＥＫ－Ｃ）在拉伸及冲击破坏条件下的断面形态，利用材料力学试验机测定ＳＣＦ／ＰＥＫ－Ｃ的应力－应变曲线，进而讨论了短碳纤维／聚芳醚酮复合材料的断裂机理。结果表明：此复合材料的微现破坏机理具有多样性。
The cross-sectional morphology of SCF / PEK-C under tension and impact failure conditions was observed by scanning electron microscopy (SEM). The stress of SCF / PEK-C was measured by a material mechanical testing machine - strain curve, and then discussed the fracture mechanism of short carbon fiber / poly (aryl ether ketone) composites. The results show that the composites have a variety of micro-failure mechanisms.
