摘要研究T700/3234复合材料薄壁圆管轴向压溃吸能特性受纤维铺层角度变化的影响规律。首先开展复合材料力学性能试验和薄壁圆管轴向准静态压溃试验。通过对比圆管轴向压溃峰值载荷及比吸能等指标的试验结果，验证建立的复合材料圆管有限元模型和分析方法。其次，基于验证的有限元分析方法，探讨了复合材料纤维铺层角度的变化对薄壁圆管轴向压溃吸能特性的影响规律。结果表明，在准静态轴向压缩载荷下，随着纤维铺层角度的增大，比吸能先增大后减小；纤维角度为±45°时，初始峰值载荷最低，载荷效率最高，圆管易于进入渐进破坏吸能阶段。研究结果可为复合材料纤维铺层角度设计及复合材料薄壁结构有限元建模提供参考。

Abstract：

Aiming at revealing effect of ply orientations on energy-absorbing characteristics of T700/3234 composite thin-walled circular tubes under axial compression, the material properties were measured and quasi-static axial crush tests of thin-walled circular tubes were performed.The finite element model and analysis method of the composite tube were validated by comparing the experimental results of peak load and specific energy absorption of composite thin-walled circular tubes under axial compression.Based on the validated finite element model and analysis method, effect of ply orientations on energy-absorbing characteristics of composite thin-walled circular tubes under axial compression was discussed.The results show that the SEA increase almost linearly first, and then decreases to a certain extent with the ply orientations increase for composite thin-walled circular tubes under quasi-static axial compression.The initial peak load is the lowest and load efficiency is the highest when ply orientation is relatively ±45°, and it is easier to achieve progressive failure energy absorption stage.The research results can be used as a reference for the design of composite fiber plies and the finite element modeling of thin-walled composite structures.
