摘要
编织复合材料中纤维束在空间分布的复杂性,导致其与层合复合材料力学性能分析的本质差别。本文概述了编织复合材料的力学特点及其一般研究步骤,详细介绍了目前几种常见的数值模拟模型,分析了其存在的优缺点,依此指导计算模型的合理选择,使之能对编织复合材料进行较为精确的力学性能预报,并为今后的研究提供指导。
In braided composites, the analysis of mechanical performance is very different from laminates because of complicated reinforced-fiber space distribution. This paper summarizes the mechanical characteristics and general study steps of braided composites. Several familiar models of numerical simulation are presented in detail. The model＇s merit and demerit are analysed, which can give some derections to choose reasonable numerical model and predict mechanical performance accurately. Thus, the future research can be guided using the above analysis.
