Innovative Matrix Systems for Carbon Fiber Reinforced Composite Tactical Rocket Motor Applications

The current matrix materials used for composite tactical rocket motor applications are based on legacy systems with proven performance derived from strategic and space-launch applications. The latency of these resin systems and corresponding long cure cycles are adequate for wet filament winding large structures and low rate production. However, transitioning these matrix materials to the production of tactical rocket motor cases has resulted in inefficient manufacturing. Moreover, these resins were developed with a primary focus on fiber-translation as opposed to a balance of properties and damage tolerance required for tactical rocket motor cases. Accordingly, the objective of this work is to develop innovative matrix systems for carbon fiber reinforced composite tactical rocket motor applications that are optimized for processing and performance. The developed wet-winding resin systems will be compatible with other composite manufacturing methods such as infusion processes and pultrusion. Thus, a universal resin matrix will be created that enables combinations of manufacturing methods to be utilized which provide the greatest benefit from a performance and cost standpoint.
