【摘要】 本文通过双悬臂梁（ＢＣＢ）实验和末端缺口三点弯曲（ＥＮＦ）实验，研究了碳纤维增强国产聚苯硫醚复合材料的断裂韧性，着重考察ＴＣＦ／ＰＰＳ的ＧⅠｃ、ＧⅡｃ在不同热处理条件下的变化情况，并对其机理作了分析。研究结果，对合理使用ＣＦ／ＰＰＳ复合材料和充分发挥其作用是很有实际意义的。更多还原

【Abstract】 In this paper, fracture mechanisms of carbon fiber-reinforced PPS (CF/PPS) composites are studied by Double Cantilever Beam (DCB) and End-NotchFlexcural (ENF) experiments.The variation of GIC and GⅡc of the compositeswith different conditions of heat-treatment is examined and the mechanismsare analyzed. The results of this paper are of significance to rational application of CF/PPS composites.更多还原
