Innovative Approaches in the Design and Fabrication of 3D-Braided Ceramic Matrix Composite Fasteners

The aeronautical and space industries need new technologies in the design and fabrication of 3-Dimensional Ceramic Matrix Composite fasteners for mechanically attaching composite propulsion and structural components to metals, both on, and within, the aerostructure body. Novel fasteners must be able to withstand environmental challenges including extreme temperatures, corrosion (such as the affects from exposure to water, salt and engine-related chemicals), erosion, abrasion and the cyclic effects from mechanical vibration and thermal sources. In support of this objective, the Offeror proposes an innovative solution focused on 3D-braided ceramic matrix composite fasteners which will exhibit increased mechanical strength properties, resistance to crack-propagation, engineered thermal conductivity and a potential for long-service duty performance at ultra-high temperatures.
