Patent ID: 7670969

Claim:
A method of forming a multilayer woven object with off-axis reinforcement, the method comprising the steps of: interweaving a first preform with warp fibers aligned substantially parallel with the 0° direction and fill fibers aligned substantially parallel with the 90° (hoop) direction; interweaving one or more additional preforms with warp fibers aligned substantially parallel with the 0° direction and fill fibers aligned substantially parallel with the 90° (hoop) direction; twisting said first preform in a first direction by restraining a first portion of said first preform in relation to a second portion of said first preform, wherein said twisting allows the warp fibers to twist off the 0° direction in a negative direction while the fill or hoop fibers remain substantially parallel to the 90° direction; twisting said one or more additional preforms in a second direction by restraining a first portion of said one or more additional preforms in relation to a second portion of said one or more additional preforms, wherein said twisting allows the warp fibers to twist off the 0° direction in a positive direction while the fill or hoop fibers remain substantially parallel to the 90° direction; and layering said one or more additional preforms with said first preform.
