Abstract

Manufacturing technology on closely uniformed less defective matrix formation of continuous SiC fiber-reinforced SiC matrix (SiC) composites is developed. As a matrix formation process, polymer impregnation and pyrolysis (PIP) is adopted as it is advantageous in regards of applicability and controllability. Main process parameters in material selection, molding and heating are systematically investigated. Executive methodology forms well-densified homogeneous matrix in wide types of texture and geometry. Important guideline to get high mechanical performance with sufficient hermeticity is also acquired. The application of the ceramic matrix composites (CMCs) for high temperature constructions such as airframes and engines are getting attractions as an important investigation issue to materialize hypersonic transports or space planes. As one of the candidates, SiC fiber-reinforced SiC matrix (SiC) composites that are regarded to be promised from the aspect of the stability at high temperature in air. In order to materialize high mechanical features on the CMC after providing the structure to enable pseudo-ductility and damage tolerance, less-deficit uniformed dense matrix formation is important by which satisfactory stress propagation and load distribution are achieved with appropriate interfacial features.
