Abstract
A corner fitting preform and a method of forming a corner fitting preform including steps integrally weaving a base or parent material with one or more flanges or legs that extend from the base is disclosed. The flat woven preform includes specially engineered areas within the legs or flanges that have continuous warp yarns which are not woven. The unwoven areas provide a hinge which allows the flanges of the preform to fold around a corner. After folding, the excess unwoven warp yarns are pulled back through the woven portion of the legs or flanges to produce a preform with continuous warp yarn reinforcement around the corner.
