摘要
分析了三维复合材料的基本原理及其制作方法，从微观力学模型出发，对其弹性常数进行了预测，分析了这些常数随参数变化的情况，并与实验进行了比较，结果表明本文的预测方法是比较准确的。
The laminated composites present low transverse strength and stiffness because of easy to produce delamination. This problem is well solved by using a new kind of structural composites,that is,threedimensional composites. In this paper,the basic principle and fabricating method of 3-D composites are discribed. From establishing the micro-mechanicalmodel, the elastic properties of 3-D composites are predicated in theoretically,and the effects of textile structural parameters on properties are analysed. The comparison between the theoretical and experimental results is performed,it shows a good agreement.
