Effect of Matrix Toughness and Stack Sequences on Tensile Property of Angle-ply Hybrid Fiber Composites

本文研究了基体韧性和铺层方式对± 4 5°铺层的玻璃纤维、碳纤维及其混杂纤维复合材料拉伸断裂性能和损伤行为的影响。实验结果表明 ,采用混杂纤维有利于提高复合材料的拉伸强度和断裂应变 ,呈正的混杂效应 ;

In the paper, we investigated the effect of matrix toughness and stack sequence on tensile and damage properties of ±450 angle-ply composites reinforced with glass fiber, carbon fiber and hybrid fiber. The results showed that hybrid fiber could increase tensile strength and failure strain of the composites and there was a positive hybrid effect. When the matrix was toughened, the damage property of the composites would be improved.
