3 Three-Dimensional Woven Corner Fitting with Lap Joint Preforms

摘要

A three-dimensional corner lap joint preform; And a method for forming a three-dimensional corner-lap joint preform comprising a woven fabric flange are disclosed. The fabric flange has at least one leg extending from the flange. The legs may include one or more independently woven portions, which allow the legs to form a corner without darting or adding additional reinforcement. The independently woven portions may comprise tapered fibers that are not woven into the preform. The non-woven zones allow removal of portions of the legs prior to formation of the corners, such that the leg portions overlap to form a lap joint.
