Investigation of the Properties of Carbon-Carbon Composites and Their Relationship to Nondestructive Test Measurements

Abstract

Factors affecting the quality and performances of carbon-carbon composites are identified and evaluated by nondestructive and destructive methods. Correlations existed between the nondestructive test response data and the physical and mechanical property measurements are determined. A number of different types of defects were intentionally introduced during the processing steps to aid in this evaluation. The characterization of the VYB 70 1/2 yarn has indicated that considerable weight losses and shrinkages occur upon heating. The Thornel 50 and Modmor II graphite fibers did not mdergo any significant weight loss under similar conditions.
