本研究旨在探讨多重纤维缠绕复合管的压溃特性与破坏模式。采用纤维缠绕法制备了玻璃纤维增强塑料（GFRP）/碳纤维增强塑料（CFRP）/铝（Al）复合管和CFRP/Al复合管两种复合管。研究了典型载荷-位移曲线、破坏模式、缠绕铺层、缠绕角及相互作用对耐撞性的影响。结果表明，混杂试件的破坏模式主要为渐进脆性开裂、CFRP层间分层破坏和铝管层间菱形破坏。增加混杂铺层的数量可以提高复合材料的比吸能（SE A）、吸能（EA）和峰值压碎力（P CF）。在30° ~ 60°（缠绕角度为沿着管轴向）范围内，随着缠绕角度的增大，复合管的P C F值逐渐减小，而缠绕角度为45°的复合管的S E A和E A值最大。从理论上分析了相互作用对承载能力的影响，表明不同材料之间的相互作用可以有效地提高吸能能力。纤维缠绕，真空袋成型和嵌套制造工艺之间的比较进行和纤维缠绕技术表现出最高的耐撞性的CFRP/Al混合管的改善。
This study aims to explore the crushing characteristics and failure modes of multiple filament winding hybrid tubes. Two types of hybrid tubes, namely Glass fiber reinforced plastics (GFRP)/carbon fiber reinforced plastics (CFRP)/aluminum (Al) hybrid tubes and CFRP/Al, were fabricated by the filament winding process. The typical load-displacement curves, failure modes, effects of winding plies, winding angle and interaction on crashworthiness were explored. It showed that the failure modes of hybrid specimens were predominated by progressive brittle crack, delamination mode in CFRP layers and diamond failure mode in aluminum tube. Increasing hybrid plies increased the specific energy absorption (S E A), energy absorption (E A) and peak crushing force (P C F). The P C F of the hybrid tubes decreased with increasing CFRP winding angle from 30° to 60°(winding angle of 0° was along the axial direction of the tube) while the hybrid tubes with the winding angle of 45° showed the highest S E A and E A. A theoretical analysis was conducted on the effect of interaction on load bearing capacity and it is showed that the interactions between different materials can effectively enhance energy absorption. A comparison among the filament winding, vacuum bag forming and nested manufacturing processes was performed and the filament winding technique exhibited the highest improvement in crashworthiness of CFRP/Al hybrid tubes.
