Robust and Re-Useable MCMC TPS(1000-461)

Triton Systems will demonstrate self-healing, controlled thermal expansion carbon fiber reinforced SiC matrix composites (CMCs) enabling oxidation and damage resistant components for hypersonic vehicle TPS and engine hot sections. Triton's unique materials system design approach to oxidation protection and self-healing behavior focuses on the entire system and not just a surface coating. Our approach also allows innovative design concepts using Triton's hybrid CMC and MMC materials (MCMC). Engineered microstructures for the fiber-matrix interface, mixed oxide glassy matrix modifiers imparting self-healing behavior to the basic SiC based matrix, and impregnation materials sealing the composite from oxygen ingress at temperatures over 4000F makes this TPS concept ideal for reusable TPS. Triton's self-healing micro-engineered CMC materials include alloyed and combined particle inclusions in the matrix that form an array of mixed oxide glassy phases when exposed to oxygen. The combination of these approaches provides novel TPS concepts in many long life applications needed to meet AF space vehicle goals. Triton's innovative MCMC also has significant load carrying capability, allowing integrated TPS/structure concepts to improve vehicle packaging while enhancing flight envelope performance. Triton will work closely with its four major system integrator team members to incorporate novel designs into emerging prototype TPS systems.
