摘要

"Pre form three-dimensional woven composite structure and methods for producing preform and to form the three-dimensional woven pre form" abstract the present invention relates to a pre - three-dimensional shape with corner joints overlapping and a method to form a pre form tridimens Ional with corner joints which includes a flange overlapping the fabric with one or more legs extending from delE. the legs may include one or more parties made independently for forming a corner without dardejar leg or add extra reinforcement. The parties may include warp fibers woven independently are not woven pre form.The area is not woven allows to remove part of the leg prior to forming the corner, thereby allowing the parts of the leg overlap and form a lap joint. 2 / 2 1 / 1
