Decoupling Multiscale Analysis of Textile Composite Considering Deformation of Fiber Yarns during Weaving and Molding

Abstract

A novel multiscale simulation scheme for textile composites is proposed, which accurately predicts their mechanical properties. A key aspect of our method is the numerical construction of their representative volume elements by considering the fiber yarn deformations during weaving and molding of textile composites. We found that fiber yarn deformations during weaving and molding can be precisely computed using a novel method for modeling dry yarn mechanical behaviors with beam and solid elements. We validated our proposed method by comparing its mechanical property predictions with the experimental results obtained from tensile, compression, and bending tests of carbon fiber composites. The validation demonstrated that our method can accurately and robustly predict the mechanical properties of a composite by considering fiber yarn deformations during weaving and molding.
