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.
