Design 3D Models of Textile Structural Composites

The three-dimension Woven and braided geometrical model and the animating simulation of the craft process is proposed based on the characteristics of the textile structural composites and craft.the state of intertwisted and tightly squeezing yarns in model is taken into account which results in yarns curving and deforming.With comparing the established model and images which obtaining from slice-making and data acquisition and image processing,reasonable fitting curves of yarn center line are achieved.The investigation offers a fundamental support to predict effective elastic properties and RTM simulating work.
