The present invention relates to a manufacturing method of an oxidation resistance carbon composite, and an oxidation resistance carbon composite and, more specifically, to a manufacturing method of an oxidation resistance carbon composite with multi-layer coatings applied thereto, and an oxidation resistance carbon composite manufactured by the same. The method comprises the steps of: preparing a carbon composite; performing primary coating of silicon carbide (SiC) on the surface of the prepared carbon composite by a chemical vapor reaction method; and performing secondary coating of SiC on the carbon composite to which the SiC is firstly coated by a chemical vapor deposition (CVD) method. Therefore, performance such as oxidation resistance, heat resistance, and abrasion resistance can be improved on the surface of the carbon composite. 본 발명은 내산화성 탄소 복합재 제조방법 및 내산화성 탄소 복합재에 관한 것으로, 보다 상세하게는 탄소 복합재를 준비하고, 준비된 탄소 복합재의 표면에 화학기상 반응(Chemical Vapor Reaction) 방법으로 탄화규소(SiC)를 1차 코팅하며, 상기 탄화규소(SiC)가 1차 코팅된 탄소 복합재 위에 화학기상 증착(Chemical Vapor Deposition) 방법으로 탄화규소(SiC)를 2차 코팅하는 과정을 통해 탄소 복합재의 표면에 내산화성, 내열성, 내삭마성 등의 성능이 향상되도록 다층 코팅이 적용된 내산화성 탄소 복합재 제조방법 및 이에 의해 제조된 내산화성 탄소 복합재에 관한 것이다.
