Abstract

Composite materials reinforced with fabric preforms made by weaving, braiding or knitting yarns are currently being considered as alternatives to tape laminates. Such fabric reinforced "textile" composites have potential for improved impact and delamination resistance. In this study, braid composites of 2${\times}$2 and 2D triaxial fabricated under different braid angle by using parallel yarns. Middle-end yarns were inserted between the braider yarns and axial yarn were inserted in circular braids. The tensile properties decreased with the increase in the braid angle. The tensile strength of inlaid axial yarn composites was higher than that of inlaid middle-end yarn composites. The tensile strength of 2D triaxially braided composites could be calculated by using braid parameters such as braid structure, yarn size, yarn spacing, and crimp.
