Continuous SiC fiber reinforced SiC matrix composites (SiC/SiC) have been studied and developed for high temperature and fusion applications. In this study, SiC/SiC composite was fabricated by polymer impregnation and pyrolysis process with LPVCS , a liquid precursor with active Si–H and ‐ CH = CH 2 groups. The cross‐link and ceramization processes of LPVCS were studied and SiC/SiC composite was fabricated with LPVCS . The porosity and mechanical properties of the SiC/SiC composite was investigated, and the results indicated that the SiC/SiC composite exhibited low porosity and superior mechanical properties owing to the compact matrix derived from LPVCS .
