Mothod for manufacturing brake discs and brake disc for vehicles
Disclosed is a method for manufacturing a brake disc pad for a vehicle to provide excellent productivity due to a simple manufacturing process. According to the present invention, the method comprises: a step of impregnating carbon fiber with a dipping resin, in which a phenolic resin, pitch, and carbon nanotubes are mixed, to prepare a carbon fiber prepreg; a step of coating an oxidation prevention film forming powder, in which copper powder, SiC powder, MoSi_2 powder, and graphite powder are mixed, on a surface of the prepared carbon fiber prepreg; a green body molding step of putting the carbon fiber prepreg coated with the oxidation prevention film in a mold and pressing the mold in a vacuum atmosphere while gradually heating the same to mold a planar green body; a carbonization step of carbonizing the molded green body at a temperature range of 1,250-1,500°C in a vacuum inert gas atmosphere; and a processing step of processing the carbonized green body into a brake disk pad.
차량용 브레이크 디스크 제조방법에 대하여 개시한다. 페놀계 수지, 피치, 탄소나노튜브가 혼합된 함침수지에 카본섬유를 함침하는 단계; 준비된 카본섬유 프리프레그의 표면에 구리 분말, SiC 분말, MoSi2 분말, 그라파이트 분말이 혼합된 산화방지막 형성분말을 도포하는 단계; 산화방지막 형성분말이 도포된 카본섬유 프리프레그를 금형에 넣은 후 단계적으로 가온하는 가운데 진공 분위기에서 압축하여 판 형태의 그린 바디를 성형하는 그린 바디 성형단계; 1,250~1,500℃ 범위 온도의 진공의 불활성 가스 분위기에서 성형된 그린 바디를 탄화시켜 브레이크 디스크 소재로 준비하는 탄화단계; 및 브레이크 디스크 소재를 브레이크 디스크로 가공하는 가공단계;로 브레이크 디스크 소재가 제작된다.
