摘要
研究了PDC—Ⅱ/连续单向碳纤维复合材料的弯曲强度、层间剪切强度、冲击强度与树脂含量的关系,并观察了层间剪切和冲击破坏试样断面的形态、界面,讨论了树脂和碳纤维组分对复合材料力学性能的贡献。
Mechanical properties-resin content relationship of continuous carbon fiber re-inforced phenolphthalein polyether sulfone copolymer (PDC-Ⅱ) composites was studiedand morphology of both impact and delaminated broken section and interface of the com-posites were observed by SEM. The role of resin and fiber contributed to the compositeswas discussed.
