Abstract

복합 적층체용의 가벼운 구조물 코어로서의 사용에 적합한 편평 시이트 형태 또는 만곡 3차원 형태의 유리기포 강화 플라스틱 제품(10)은 중공의 세라믹 중심체(11,12)와 건조 수지 분말(14)의 혼합체로 제조되며 이는 열경화성 또는 고온 열가소성 수지로 만들어지고, 상기 혼합체를 가열 및 냉각시에 소정의 형태로 일체화시키기 위해 중심체 매스의 간극에 분포된다. 수지 코팅재료로부터의 폐기 부산물로서 수집된 수지 분말은 소정제품의 제조에서 리사이클리될 수 있다. 기포 제품은 상기 혼합체의 물리적 교반에 의해 중심체와 분말 수지를 먼저 혼합하고, 상기 혼합체를 경계 부재 사이의 치수 정의 영역에서 분리제를 갖는 표면위의 층으로서 적층하며, 이후 수지 분말을 용융하기에 충분한 기간동안 일정 온도로 층을 압축하거나 압축하지 않고서 열을 공급하고, 이후 상기 경화된 상태의 수지를 냉각하여 혼합체를 제품으로 일체화 하므로써 형성되며, 이후 상기 제품은 성형 영역으로부터 철회된다. 유리 또는 탄소 섬유(15)와 같은 보강 요소가 소정의 물리적 및 기계적 상태량을 위해 선택적으로 상기 혼합체에 구비된다.
