Description

Next generation high-speed missile defense systems [1] require advanced thermal protection systems (TPS) to meet performance objectives, cf. Figure 1. The development of these advanced systems requires the continued research of materials that have a TPS pedigree, i.e., carbon-carbon (C-C) composites. In particular, data is needed to support hydro-code modeling and analysis of structural responses of C-C composites to energetic events such as explosions or high-velocity impacts where distortion of the structure is extreme and the time-scales are very short. This data is typically generated using gas-gun impact testing [2,3], which is an expensive approach. An innovative and cost-effective solution for testing and measuring material properties of C-C composite materials under high strain/high strain rate loadings is needed. In response to this need, Materials Sciences Corporation in collaboration with Aerojet Rocketdyne and DE technologies proposes development of a low cost, reduced leadtime energetic based test methodology for measuring the anisotropic, high rate properties of C-C composite materials.
