Abstract

Tow Prepreg is the intermediate material for filament winding process that has been "pre-impregnated fiber tow" with resin system. As "dry filament winding" process emerges as a reliable alternative to conventional filament winding (called "wet filament winding") process, interest in tow prepreg as a material for dry filament winding is rising as well. In this article, we have reviewed the recent research trends in carbon fiber tow prepreg for high-performance rocket motor cases, fuel tanks for hydrogen vehicles and other high-quality commercial pressure vessels.

토우프리프레그는 한 가닥의 탄소섬유, 유리섬유, 아라미드 등의 보강섬유에 일정한 비율의 수지가 미리 함침되어 있는 토우 형태의 프리프레그를 의미하며, 필라멘트와인딩 공법을 위한 중간재이다. 최근 고성능 압력용기 개발에 대한 연구가 활발해지면서 기존의 습식 필라멘트와인딩 공법을 대체할 수 있는 건식 와인딩 공법을 위한 소재인 토우프리프레그에 대한 관심이 증대되고 있다. 본 논문에서는 로켓 모터케이스, 수소연료전지 자동차용 연료탱크, 산업용 고성능 압력용기 등 성능과 신뢰성을 동시에 필요로 하는 부품 제조용 소재로 주목받고 있는 탄소섬유 토우프리프레그의 국내외 최신 연구동향에 대하여 살펴보았다.
