This study aims to develop a heat-resistant composite material with high safety and reliability towards realization of re-use type space transportation system. Silicon carbide (SiC) which has high thermal conductivity and chemical inactive was adopted. To modify the brittleness of SiC, the micro-porous materials were produced by powder space holder (PSH) method. The production conditions of SiC porous materials and SiC fiber reinforced SiC porous composite material were considered. The problems of the heating process of SiC precursor polymer were solved by changing the particle size and the mixture ratio of pore formation materials. Consequently, SiC porous materials without crack with homogeneous open porous structure were obtained.
