Abstract
본 발명은 평면상 이차원 구조 탄소섬유강화 탄소복합재료 (이하 “탄소복합재”로 약칭함)의 제조방법에 관한 것이다.
본 발명은, 이차원 탄소섬유를 보강삼유로 사용하여 두꺼운 탄소 복합재제조시, 새로운 공정의 도입없이 손쉽게 탄소 복합재의 층간 분리현상을 최대한 억제함과 동시에 신속한 승온과 냉각속도조건에서 열처리하여 실행할 수 있는 제조방법을 제공하는 것을 목적으로 한다.
본 발명은 열경화성수지를 사용하여 액상 함침법에 따라 두꺼운 이차원 구조 탄소 복합재를 제조하는 데 있어서, 약 0.1∼2㎜의 분쇄된 탄소섬유를 2∼20중량% 첨가하여 초벌성형체를 성형한 다음, 수회에 걸친 고밀도화 공정을 거치는 것을 특징으로 한다.
