摘要

This research paper examines the damage mechanisms and reductions to the tensile properties of E-glass yearns during weaving of three-dimensional (3D) fabrics for polymer-based composites. The paper also asses the influence of weaving damage to load- bearing glass years on the tensile properties of 3D orthogonal woven composites. It is found that damage occurs to years at most stages of the 3D weaving process due to abrasion and breakage caused when sliding against the loom machinery. The abrasion damage causes a large reduction (～30/100) to the tensile strength of the dry woven years, although the tensile stiffness remains un- affected.
