Ultra Refractory Composites: Enabling Performance and Cost Payoffs For Divert Propulsion Components

Ceramic Composites Inc. proposes its novel fiber reinforced Ultra Refactory Composites as an enabling technology for replacement of heavy and expensive rhenium components in BMDO divert and attitude systems (DACS). A systematic approach for optimizing agraded C-Re matrix and a graded C-HfC/SiC matrix densification process for different carbon fiber preforms; i.e. for divert thrusters and hot gas valve assemblies, respectively, is outlined. Multiple hot firing tests in a solid DACS envirornment by OEM ATKThiokol, will provide the success criteria necessary to transition to full scale component testing in phase II. Weight savings of 7:1 and cost savings of 5:1 compared to solid rhenium component are achievable. Millions of dollars in production costavoidance and enhanced performance capabilities will be realized for Standard Missile III interceptor, a critical part of the Theater Missile Defense' s AEGIS Weapon System. Similar benefits are achievable for THAAD DACS components as well as advancedaricraft propulsion systems and hypersonic missiles. Major spinoff commercial market opportunities have also been identified.
