Metallic Joining to Advanced Ceramic Composites, Phase II

The Orion Launch Abort System (LAS) utilizes attitude control motors (ACM) with advanced ceramic composite components that function as a valve control system to allow for safe maneuverability away from danger. This system is made steerable due to the valve controlled thrusters which utilize advanced ceramic pintles made of 4D C/C-SiC that are attached to metallic structures and actuated.

During the Phase I effort, an innovative technique to join metallics with the advanced ceramic composites was demonstrated. Detailed characterization confirmed the deposited metal (Inconel 625) produced during this investigation had good adherence to C-C/SiC pintles and no interfacial reactions occurred during deposition or elevated temperature exposure. In Phase II, the joining interface will be optimized and pintle assembles will be produced for hot fire testing with Orbital ATK. Additional CMC materials and components will also be developed.
