Abstract

복합물의 중량을 기준으로 열경화성 폴리에스테르 매트릭스 내에 30중량% 이상의 강화 섬유를 함유하고 있는 섬유 강화 열경화성 폴리에스테르 복합물을 제조하기 위한 진공 보조 이송 성형법.
열경화성 폴리에스테르 매트릭스가 매트릭스 전구물질의 중량을 기준으로 a) 150 내지 190의 분자량/이중결합 인자를 가진 20 내지 60%의 불포화 폴리에스테르 수지; b) 30 내지 70%의 반응성 단량체; c) 폴리에스테르수지와 반응성 단량체의 블렌드물에 혼화성이 있는 1 내지 25%의 열가소성 고분자; d) 개시량의 자유리디칼개시제를 함유하는 단일상 매트릭스 전구물질로부터 제조된다.
선체 및 트럭 차체 패널과 같은 성형물을 제조하는 것은 겔 코팅 및 신 라미네이트(shin laminate)인 상기의 방법에 따라 만들어진 복합물을 포함한다.
