| 中文摘要 | 通过二维三向编织复合材料圆管的轴向准静态压缩试验,分析了编织复合材料圆管的压缩破坏机理和吸能特性,并探讨了编织参数对吸能特性的影响。试验中观察到4种破坏模式:分瓣破坏、局部屈曲、块状断裂和突发破坏。在纤维体积分数相同的情况下,随着编织层数的增加和编织角的减小,圆管的吸能能力有所提高。二维三向编织复合材料圆管是一种较好的吸能材料,具有较高的单位质量吸能特性。; Quasi-static axial compression tests were performed to study the failure mechanisms and energy Absorption characteristic of the 2D triaxially braided composite circular tubes.The effect of the braid parameters on the energy Absorption characteristic was investigated.Four primary failure modes observed in the tests are frond fracture,local buckling,fragmental failure and catastrophic failure.As the braid layers increase or the braid angle decreases,the circular tubes have higher specific energy Absorption(Es) in the same fiber volume fraction.The 2D triaxially braided composite circular tubes with high Es are very effective energy Absorbers.; 国家自然科学基金(50405003); 清华大学基础研究基金(JC2003018) |
