Abstract

본 발명은 복합재 압력용기와의 접착력이 증진된 인슈레이션 및 그 제조방법에 관한 것으로, 복합재 압력용기의 사용되는 인슈레이션을 제조함에 있어 금형(4)상에 인슈레이션(1)의 외면을 형성하기 위한 탄소섬유 패브릭/수지 프리프레그(2)를 적층하는 단계와, 상기 프리프레그(2) 상에 인슈레이션(1)의 설계두께 만큼 미가황 인슈레이션 고무(3)를 적층하는 단계와, 상기와 같이 적층된 프리프레그(2)와 미가황 인슈레이션 고무(3)가 일체가 되도록 가황하면서 오토크레이브 성형하는 단계로 구성된다. 이와 같은 본 발명에 의하면 압력용기와 인슈레이션 사이의 접착력이 좋아져 소재의 가격이 저렴한 습식와인딩공법을 사용하더라도 압력용기와 인슈레이션 사이의 접착이 양호하게 이루어지는 잇점이 있다.
