The feasibility of utilizing real-time computed tomography (CT) to characterize and monitor the growth of defects in composite materials as they undergo destructive testing was investigated. The equipment consisted of an Imatron C-100 Ultrafast CT Scanner, a modified high-temperature laboratory oven, and a motor driven hydraulic ram. Three types of composites were studied: carbon-carbon, carbon-phenolic, and glass-phenolic. Time-density profiles were obtained for each type. In general, the density of the samples decreased slightly upon impact of the ram, then sharply increased before dropping back to a slightly lower constant value.
