Microstructural Study of Cloth-Reinforced Carbon-Carbon Laminates

Abstract

The microstructure of cloth-reinforced carbon-carbon laminates was studied, with emphasis on features observable at relatively low magnifications, such as: the geometric shape of fiber bundles (yarns), yarn crimp, fiber orientations, nesting of cloth layers, and minimechanical microcracking. The development of these features during processing is discussed, with the aid of observations made with a hot-stage-equipped microscope. Computer-aided digital image analysis techniques are applied to the quantification of yarn shapes. Further quantifications of microstructures are recommended as relevant to improved understanding of the links among processing, microstructure, and thermomechanical behavior of carbon-carbon materials.
