Research Institution

During the Phase I NASA SBIR, MATECH GSM (MG) has developed and evaluated the world's first ultra-high temperature (UHT) Zr-(O)-C ceramic fiber pre-form / organic ablative matrix composite TPS system.
This Phase II NASA SBIR Proposal from MG seeks to expand this technology to the following areas:
1)Microstructural level refinements and optimization of the char- and ablator phases for more reproducible material systems
2)Scaling-up for the fabrication of a larger and more complex-shape geometry
3)TPS design data generation with extensive arc-jet testing for a full TPS Component demonstration in Phase III.
In this TPS material concept, the "char" phase is UHT zirconium carbide (Zr(O)C) ceramic fiber pre-forms, which have dual functions of high compressive strength of ligaments and non-recession of fiber components after matrix ablation. MG's ablative TPS are designed to retain their shape, thereby reducing the thickness requirement and lowering the TPS total mass, crucial at high re-entry velocity. MG's new ablator slowly absorbs high levels of energy during high temperature ablation.
At the completion of the Phase II-Base and Phase II-Option program, MG will have fabricated a high specific strength C-Zr(O)C / C-ablator (CZOCA) and have demonstrated one TPS component, operational at > 5000oF.
