This work experimentally explores the post-impact behaviour of thin-ply angle-ply pseudo-ductile carbon fibre laminates subjected to tensile load. Indentation and low-speed impact tests were performed on standard tensile test specimens. Non-destructive tests were used to investigate the damage propagation. Digital Image Correlation (DIC) was adopted to detect the strain distribution during tensile tests. Post-damage pseudo-ductile behaviour was retained in angle-ply hybrid composites subjected to tensile loading conditions.
本研究通过实验探索了承受拉伸载荷的薄铺层角铺层伪延性碳纤维层合板的冲击后行为。对标准拉伸试验样品进行了压痕和低速冲击试验。采用无损检测来研究损伤扩展。在拉伸试验过程中采用数字图像相关技术(DIC)来检测应变分布。在拉伸加载条件下,角铺层混杂复合材料保留了损伤后的伪延性行为。
