Title: High-Strength Carbide-Based Fibrous Monolith Materials for Solid Rocket Nozzles
Agency / Branch: DOD / MDA
Contract: N00167-04-C-0053
Award Amount: $100,000.00


On this Phase I STTR program, Advanced Ceramics Research Inc. (ACR) will team with the University of Missouri ¿V Rolla (UMR) to develop high strength, thermal shock resistant tantalum carbide (TaC) or hafnium carbide (HfC)-based Fibrous Monolith composite materials for use in ultra-high temperature (>6000,aF) solid rocket motor environments. These materials will exhibit the high toughness of fiber reinforced composites with the full density and low ablation rates of monolithic structures. The three main technical challenges preventing the insertion of TaC/HfC based materials into aluminized propulsion systems are 1) material ultimate strength, 2) material oxidation/spalling resistance, and 3) thermal shock resistance. UMR will address the material strength issue through the use of a patented (pending) process which has been shown to greatly improve refractory ceramic material strength, as well as through their general expertise with respect to ceramic materials processing. The oxidation issue will be addressed by UMR and ACR through the exploration of mixed oxide systems that increase the oxide melting point and prevent phase transformation and spalling of oxide coatings at high temperature. ACR will also address the thermal shock resistance issue by using a TaC or HfC-based Fibrous Monolith composite material system which has proven thermal shock resistance.
