Abstract: PURPOSE: A heat-resistant composite for preventing gas leakage is provided to block pores by carbon-penetrating into the pores and to doubly prevent gas leakage by a heat decomposition carbon layer and a carbon silicon layer. CONSTITUTION: A heat-resistant composite for preventing gas leakage(10) comprises a preform, matrix, and a first gas leakage blocking layer. The preform has a spray chamber discharging compressed gas inside, and is formed by weaving reinforced fibers. The matrix is filled between the reinforced fibers. The first gas leakage blocking layer covers the outer side of the preform to prevent the gas leakage outwards from the matrix. The matrix comprises carbon silicon. The first gas leakage blocking layer comprises silicon carbide and carbon.
