The Phase I proposal shall demonstrate low cost Silicon Oxycarbide (SiOC) fibrous-walled high temperature honeycomb structures, hat stiffeners, and rigid fibrous insulators. These robust structural airframe materials can be densified with SiOC and ZrOC (for ultra-high temperature) matrix materials to produce a suite of advanced heat shield components. These airframe material systems and associated fabrication methodology offers robust multifunctional structural high temperature thermal protection systems (TPS) for next generation RALV and demanding high-mass planetary atmospheric entry, descent, and landing (PAES-EDL) applications. This MATECH SBIR proposal offers a platform of unique formable ceramic materials using Net Shape processing for low cost, readily scale-able manufacturing. Potential applications for this innovative technology include hypersonic leading edges, hypersonic airframes, and heat shields for NASA vehicles. These vehicles include hypersonic re-entry from orbit, h Potential Non-NASA applications include hot component parts on missiles, such as MDA's THAAD and SM-3. In addition, MATECH has identified heat shields for the private sector led efforts towards the return of manned space activities in LEO as potentially benefiting from this proposed technology. This could be potentially applied to the on-going efforts of SpaceX, Virgin Inter-Galactic, and Orbital Sciences.
