In-Plane Elastic Properties of Stitched Plain Weave Composite Laminate

A representative volume element method and a novel mesomechanical-based polyline model are proposed to describe the misalignment of in-plane fibers induced by the insertion of stitch thread. A multi-scale mathematical model of in-plane elastic parameters for stitched composite laminate is established with ply-angle and stitch parameters as well as material parameters taken into account. Based on the fabrication of specimens and the verification...
