The tensile properties of carbon matrices at temperatures up to 2200 °C Original Research Article

Tensile properties of carbon matrices for carbon/carbon composites made via chemical vapor infiltration (CVI) of a fiber preform, were determined from room temperature to 2200 °C. Microcomposite test specimens were used. For this purpose, a carbon coating was deposited on low modulus carbon fibers via chemical vapor deposition based techniques. The mechanical behavior of the carbon matrix was derived from the stress–strain curves obtained with the single filament reinforced microcomposites. It was related to features of nanostructure characterized using X-ray diffractometry. The trends are discussed with respect to those evidenced on carbon fibers in a previous paper.
