The paper reviews the development in the analytical theory of mechanical behavior of composites, pointing out the problems existed, presenting creatively the concept of yarn state, solving the descriptive problem of perform structure of any woven composites and laying the foundation for predetermining the elastic behavior of 3-d woven composites with computer. On the basis of yarn state, the relative cross section deformation theory is introduced, the yarn cross section deformation is studied, and the experiential formula is described in the paper on the basis of experiment. The crimping state of yarn is studied, the classical "straight warp view"is modified, and the crimp height value of crimped yarn is studied. At the same time, with shrinkage rate sine method, the paper proposes the idea which imitate the shape of crimped yarn. With the third power template curve, the paper describes the microgeometry structure of fabric, finding a brief and precise approach for the calculation of mechanical behavior of composites.

本文回顾了复合材料力学性能分析理论的发展，指出了存在的问题，创造性地提出了纱态概念，解决了任意结构机织复合材料预制件结构表征问题，进而为用计算机预报三维机织复合材料的弹性性能打下了基础；基于纱态概念，提出了相对截面变形理论，研究了纱线截面变形情况，在实验的基础上给出了纱线截变经验公式；研究了纱线屈曲状态，修正了传统的&地经纱直线论&，提出了以纱线缩率研究屈曲峰谷值的思想，同时以三次样条曲线拟合了纱线的卷曲形状，较好地描述了织物的细观几何结构，为复合材料力学性能的计算找到了一条既比较简便又比较精确的途径。
