摘要
三维编织复合材料因内部存在由连续纤维束形成的空间网状结构,相比于传统层合复合材料具有更高的层间强度,相比于金属材料具有更高的抗冲击损伤和抗裂纹扩展能力。详细介绍了三维编织复合材料的细观几何建模方法,综述了三维编织复合材料动态拉伸、压缩性能,动态失效准则以及高速冲击性能等方面的研究进展,指出三维编织复合材料在细观几何建模和动态拉伸试验方面的未来研究方向。
3D braided composites have a spatial network structure formed by continuous fiber bundles inside;therefore 3D braided composites have higher interlayer strength than traditional laminated composites,and have higher impact resistance and crack propagation resistance than metal materials.The meso-scale geometrical modeling methods of 3D braided composites are described in detail.The research progress on dynamic tensile and compression properties,dynamic failure criteria and high-speed impact properties of 3D braided composites is reviewed.The future research direction in meso-scale geometrical modeling and dynamic tensile testing of 3D braided composites is pointed out.
