Multiaxis Three-Dimensional Flat Woven Preforms - Tube Carrier Weaving

A multiaxis three-dimensional (3D) flat woven preform and a weaving method have been developed. The structure has five yarn sets, which are bias(+) and bias(—), warp, filling and Z-yarns. The weaving method has been introduced to form the structure. An experimental prototype was constructed to trial the method. In this technique, called “tube-carrier weaving”, bias(+) and bias(—) yarns are closely laid all over the surface. The preliminary study shows that the structure and weaving method seem feasible under the test conditions.
