Abstract
In recent years, carbon-carbon composite materials have come into widespread use in aerospace industries. These materials are particularly attractive for high temperature applications due to their thermal and mechanical behavior. Few quantitative measurements, however, have been made to characterize these materials. One problem encountered with carbon-carbon composites is porosity. Materials engineers have determined that degree of porosity is correlated to inter-laminar shear strength in carbon-carbon composites. Since repetition of the carbon-carbon processing cycle reduces porosity, a technique for assessing porosity between processing cycles that is non-contacting and does not contaminate the material would be of value. A material property which is related to density and therefore to porosity, is thermal diffusivity. Thermal diffusivity is easily measured non-contactingly and remotely with infrared techniques and is therefore an attractive candidate measurement for assessing porosity between processing cycles of carbon-carbon composites.
