Development of silicone matrix-based advanced composites for thermal protection

Abstract

A new class of silicone matrix-based composites has been developed, particularly for use in the thermal protection of missile launch structures. In this application. screening tests have shown that these materials, coded SM8000, offer three-fold performance improvement over conventional phenolic-based composites. Initial investigations designed to identify commercial opportunities for the material have also met with some success. Promising applications as diverse as commercial jet-engine fire shields and high-temperature automotive gaskets have illustrated the potential widespread use of this type of material. This paper will examine the development, properties and applications of these silicone matrix composites.
