摘　　要：三维编织碳纤维增强铝基复合材料(以下简称为3D-CF/Al复合材料)因内部存在由连续碳纤维束构成的空间网状结构,具有更高的比强度、比刚度、抗冲击损伤和抗裂纹扩展能力。文章综述了编织结构和制备工艺参数对3D-CF/Al复合材料力学性能的影响以及关于其细观结构建模与力学分析方面的研究进展,并针对3D-CF/Al复合材料的设计、制备与应用的关联环节,提出一种宏细观结构与力学协同的理论构想,以期实现复合材料的数字化设计、制造与性能预测。Three-dimensional woven carbon fiber-reinforced aluminum matrix composites(abbreviated as 3D-CF/Al composites)have higher specific strength,specific stiffness,impact damage resistance and crack expansion resistance due to the presence of a spatial mesh structure composed of continuous carbon fiber bundles inside.This paper reviews the effects of weave structure and preparation process parameters on the mechanical properties of 3D-CF/Al composites and the progress of research on meso-scale structure modeling and mechanical analysis,and proposes a theoretical concept of macro-meso-scale structure and mechanical synergy for the design,preparation and application of 3D-CF/Al composites in order to realize the digital design,manufacturing and performance of composites.
