| Abstract Scope |
A three-directional “3D” C/C-composite made of continuous-non-woven ex PAN (polyacrylonitrile based) carbon-fibers and CVI-matrix (sample D) r; and a two-directional “2D” C/C composite consisting of randomly oriented chopped pitch-based carbon fibers and a combination of CVI and charred resin matrix (sample A). Impact of oxidation on thermal properties are observed through the thickness direction. It was observed that 2D pitch-baed C/C exhibit lower thermal conductivity as compared to the 3D PAN-based C/C composites. The microsttucutre observed by PLM shows increased graphitic structure for 3D PAN-based C/C followed by 2D pitch-based C/C composites. The structural integrity of HTT C/C is shown to increase against oxidation. |
