Abstract

Directional hemispherical reflectance at 10.6 μm of three modification of carbon-carbon (c/c) composites heated in the air by CW CO₂-laser radiation with irradiances ranged from 90 to 16000 Wcm^-2 was measured. At the incident beam intensity of 90 Wcm^-2 the investigated materials reflectance were found to increase with increasing temperature. When irradiance is more than 200 Wcm^-2 the c/c composites reflectance at 10.6 μm is not only temperature dependent but materials modification, and laser irradiance dependent.
