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