Abstract

An experimental investigation of influence of laser radiation on the phase composition of carbon-carbon composites with different types of non-graphitizing carbon matrix and fabric fillers was made. It was shown that laser treatment formed a graphite-like structure of material. The process of graphitization is a heterogeneous crystallization. The monochromatic reflectance was measured of carbon-carbon composites within the range of 0.4 to 1.06 micrometers and 10.6 micrometers before and after laser treatment. It was shown that laser treatment causes sharp increase of oxidation of stability carbon-carbon composites in ambient air under elevated temperature.
