HIGH SPEED THREE-DIMENSIONAL WEAVING METHOD & MACHINE

摘要

A method and machine for high speed formation of a three-dimensional woven fiber structure (10) having at least two warp yarn systems (12,14, 16) having approximately zero crimp, wherein the warp (12) and filling yarns (16) are non-interlacing with each other, and are secured as an integral fabric via at least one vertical or Z yarn system (12) and the warp yarn systems (12) provided to be positioned by harness frames (W1,W2,W3,W4). The 3-D woven fabric of the present invention is fabricated on a 3-D weaving machine having rapier filling insertion that provides filling yarns insertions in unique shed openings (22) in series to produce a complete filling insertion cycle for every movement of Z-direction yarn harnesses (Z1,Z2).
