CORNERSTONE RESEARCH GROUP INC — Department of Defense SBIR Phase II: MDA15-020

Description

Global proliferation of ballistic missiles, with ever increasing performance, continues to put pressure on U.S. missile defense systems for increased kinematic reach and containment. Material weight is a primary factor limiting kinematic reach which establishes a need for advancements in material systems. CRG proposes to develop a low-cost, multifunctional thermal protection material system based on CRG’s high-temperature MG resin systems. The unique features of these materials will allow for thermal protection, combined with structural contribution, and electrical protection properties integral to the TPS material system. MG could enable a transformative change in interceptor performance, not only expanding kinematic reach, but also improving robustness, reliability, and cost. MG lightweight composites combine a non-flammable thermal barrier resin with fiber reinforcements for structural performance, and conducting pathways integral to the material system for ESD, EMI, and lightning strike protection. In Phase I, CRG demonstrated ablation performance almost twice as good as a state-of-the-art, commercially available carbon-phenolic material and mechanical performance equivalent to phenolic with similar reinforcements. MG was also shown to be conductive when subjected to a high temperature graphitization process. The MG platform presents a new paradigm in TPS design that includes multi-functionality, ease in processing, and low cost. Approved for Public Release | 16-MDA-8951 (15 December 16)
