Abstract
A three-dimensional corner lap joint preform and a method of forming a three-dimensional corner lap joint preform including a woven flange with one or more legs that extend from the flange. The legs may include one or more independently woven portions which allow formation of a corner without darting the leg or adding additional reinforcement. The independently woven portions may include warp fibers which are not woven into the preform. The unwoven area allows removal of a portion of the leg prior to formation of the corner, allowing the portions of the leg to overlap and form a lap joint.
