Program to Study the Oxidation of Carbon-Carbon Composites and Coatings on These Materials
Abstract
Carbon carbon composites are being considered for aerospace applications due to their light weight and excellent mechanical properties. Depending upon the application, carbon carbon composites are expected to be used for periods ranging from about 10 hours to a few thousand hours at temperatures above 1000 C and approaching 2200 C. A major problem in using such materials in oxidizing environments is that carbon reacts with oxygen forming gaseous carbon oxides. Two approaches are being examined to protect carbon carbon composites in oxidizing environments, in particular, the use of inhibitors to slow down the reactions, and the use of coatings whereby a barrier is developed between the composite and gases which limits the reaction rate.
