The damage to carbon-carbon composites created by projectile impacts has been characterized for a range of test conditions and for several weave constructions and processing variables. A number of subsurface damage modes have been identified on sectioned specimens in the vicinity of the crater produced by particulate impingement. In addition, studies are underway to determine the modes of failure which occurred in the material ejected from the crater. Preliminary analyses of the primary subsurface damage modes have been undertaken to define the approach that would elucidate the microstructural dependence of the impact damage.
