Lightweight, Low Cost, Hybrid Matrix Composites (HMCs) for Solid Rocket Motor Cases

This proposed Air Force Small Business Innovation Research Phase I Project seeks to demonstrate a new class of composite materials, called Hybrid Matrix Composites (HMCs), designed to operate in the 600 to 1200F temperature range, for Solid Rocket Motor (SRM) cases for future ballistic and space-lift vehicles. This proposed SBIR program is supported by ATK Launch Systems, Raytheon Missile Systems, and Lockheed Martin Missiles and Fire Control. Specifically, the objectives of this proposed SBIR program are to: · Replace Conventional OMC SRM Cases with HMC (Hybrid Matrix Composite) Cases and Eliminate External Insulation. · Decrease SRM Case Weight and Manufacturing Costs. · Increase SRM Propellant Mass Fraction. · Integrate SRM Case with Combustion Liner as a Single Component. · Investigate “Higher Efficiency” Combustion Liner Materials for Internal Insulation.
