摘要
复合材料的性能可以满足广泛的要求,因此在越来越多的结构应用中起重要的作用。尤其在航空航天方面,使用二维织物或单向带制成的层板做结构部件。然而,这些复合材料因损伤容限、冲击性能以及制造昂贵而存在着一些缺点。这些缺点可以通过采用由新的编织技术生产出来的三维增强纤维结构而得到克服。一方面这项新技术因叠层工序简单而简化生产程序,另一方面,可以提高复合材料在厚度方向上的性能,有较好的损伤容限和抗冲击性能。本文叙述了对复合材料有用的不同编织技术和制造工艺,讨论了影响编织和浸渍工艺的一些基本因素,并总结了不同增强几何形状的潜力。
Composites are gaining importance in more and more structural applications because their properties can be adapted in a wide range to the according requirements. In aerospace applications, above all, laminates of 2-D weavings or unidirectional tapes are used to build structural components. However, those composites have some disadvantages due to damage tolerance and impact properties as well as costly manufacturing. These weak points can be overcome by the use of three dimensional reinforced fiber structures, produced by new textile technologies. This can on the one hand simplify manufacturing, because the lamination process is simplified and on the other hand it leads to an improvement of properties in. thickness direction, better damage tolerance and impact behaviour. The different textile technologies and manufacturing processes, being of interest for composites, are presented. Some fundamental factors of influence on textile and impregnation process are discussed, and the potential of different reinforcing geometries are summarized.
