Abstract
A three-dimensional, woven metal fiber preform and metal braze matrix forms a high temperature metallic structural joint. The preform is used with a braze alloy matrix to join a structural skin to a flangeless frame. This same basic joint can be used to create large complex structures with very little tooling. The three-dimensional woven metal preform is a flexible element that conforms to match the skin and flangeless frame, thereby avoiding high costs associated with precision fixturing. A high temperature braze metal is used as a matrix for the wire and to join the woven preform to the skin and the frame. The edges of the preform are tapered to a feather edge to avoid stress concentrations and stiffness mismatch.
