Innovative Materials Concepts for Hypersonic Systems

High speed weapon platforms places significant demands on materials used for both the hot structures, such as the Aeroshell and control surfaces, and also for the hot components in the air-breathing propulsion systems along its hot gas path. The extremely harsh environment of flight above Mach 4 generates surface temperatures from 1000 degrees F to 3500 degrees F depending on the type of the vehicle and the location on the vehicle. New innovative, affordable, light weight, high temperature capable, and thermally & structurally efficient material concepts are required to enhance durability and carry some of the system loads without increasing parasitic weight and ultimately reducing the overall structural weight for future hypersonic platforms. Allcomp propose to develop a new generation of CMC composites that are reinforced by multi-directional and also tailorable fiber reinforcements. This new family of CMC composites are affordable, easy to fabricate and can be scale-up able for Aeroshell and Thermal Protection System (TPS) of the future hypersonic platforms
