摘要
本文采用针织和编织相结合的工艺制备了一种新型三维多层管状编织复合材料,研究了该结构材料的轴向及径向压缩性能,探讨了影响材料压缩性能的因素。结果表明,三维管状编织复合材料受到轴向和径向压缩作用力时,其载荷位移曲线规律一致,均表现为"先增加后下降"的趋势,且这种材料线性粘弹性显著,抗压性能优良;轴纱的加入,使得结构材料的轴向承压能力增强,而径向承压能力下降。本文研究结果对于该类结构材料的设计与应用具有极好的指导作用。
A new type of three-dimensional multi-layer tubular braided composites was created by a combined way of knitting and braiding,the axial and radial compression performance of the material was clearly studied,the factors affecting the performance was also explored.The results show that under axial and radial compression forces,three-dimensional tubular braided composites have the same trend of the load-displacement curve,both appeared as 'first increased and then decreased trend',and it has significant linear viscoelastic with excellent compression performance.When axial yarn joined,the axial bearing capacity of the tubular material increased,while the radial bearing ability dropped.The results have an excellent guidance both for design and application of such structural materials.
