对于纺织复合材料制成的部件的可靠设计，深入了解其失效行为和实际损伤模型是必要的。这样的模型需要的损伤和不同的损伤现象的演变，以实验确定的发病。在这种情况下，实验损伤分析策略，建议在这里，结合裂纹密度测量，声发射分析和光学显微镜与记录的刚度退化超声波速度测量。准静态测试的结果之间的相关性进行了讨论的纺织复合材料的两个选定的例子：多层平板纬编针织玻璃纤维-环氧树脂复合材料和机织玻璃纤维-聚丙烯复合材料制成的混合织物。(C)2010爱思唯尔有限公司版权所有。
For a reliable design of components made of textile composites, a deep knowledge of their failure behaviour and of realistic damage models is necessary. Such models require the onset of damage and the evolution of different damage phenomena to be determined experimentally. In this context, an experimental damage analysis strategy is proposed here that combines crack density measurements, acoustic emission analysis and optical microscopy with the recording of stiffness degradation by ultrasonic wave speed measurements. The correlation between the results of quasi-static tests is discussed for two selected examples of textile composites: multi-layered flat bed weft-knitted glass fibre-epoxy composites and woven glass fibre-polypropylene composites made of hybrid fabrics.
