Axial compressive property of 3 D braided-unidirectional hybrid tubes
-
摘要: 采用准静态轴向压缩实验和有限元仿真相结合的方法,对三维编织(3 dimensional braided,3D)-单向铺层(unidirectional ply, UD)混合的碳纤维复合材料管的轴向压缩性能和破坏机制进行了研究。实验表明,3D-UD混合管具有更稳定的压缩吸能模式;相比UD管,混合管的峰值载荷、总吸能和比吸能分别提高了20.3%、109.2%和67.1%。进一步对3D-UD混合管的破坏过程进行了有限元仿真分析,仿真得到的载荷-位移曲线与实验结果吻合较好,验证了仿真模型的有效性。结合实验结果与混合管损伤变形的仿真分析,发现由于外层3D和内层3D对夹层UD的束缚和支撑作用抑制了UD管管壁因弯折过大而断裂,同时由于夹层UD管的稳定破坏吸能使得3D管未发生严重的编织层卷曲现象,因此3D-UD混合管可以有效抵抗管壁变形,提高轴向压缩下的稳定性和吸能性。Abstract: Using the method of combining quasi-static axial compression experiment with finite element simulation, the axial compression characteristics and failure mechanisms of 3D braided-unidirectional ply (3D-UD) hybrid tubes were investigated. Test results show that the peak load, total absorbed energy and specific energy absorption (SEA) of 3D-UD hybrid tube are increased by 20.3%, 109.2% and 67.1% respectively compared to the UD tube, and the compression energy absorption mode becomes more stable. In addition, the failure process of 3D-UD hybrid tubes was simulated by finite element method. The results show that load-displacement curves curve are in good accordance with experiment results so that the reliability of the simulation model is verified. Combined with the experimental results and the simulation analysis of the damage deformation of the mixed tube, it is found that the binding and supporting effects of the outer layer 3D and the inner layer 3D on the sandwich UD inhibit the breakage of the UD tube wall due to excessive bending. At the same time, the stability failure and energy absorption of the sandwich UD tube prevent the 3D tube from serious braided layer crimp. Therefore, the mixed tube can effectively resist the wall deformation and improve the stability and energy absorption under axial compression.
