Abstract

본 발명은 열가소성 수지로된 매트릭스 수지와 액정수지로 된 조성물을 사용하여 섬유화시킨 액정수지에 의해 강화된 액정수지 복합체를 제조하는데 있어서, 상기 액정수지의 전이온도가 열가소성 수지의 최저 성형가능 온도보다 높은 액정수지 복합체의 성형 방법 및 그 장치를 제공한다. 본 발명의 방법에서는, 상기 복합체를 겉보기 전단속도 2×102-105sec-1, 액정전이 온도 이상으로 용융 압출 처리하는 것이 특징이다.
필라멘트 또는 박막 형태로 얻어지는 소재는 매트릭스 수지중의 3이상의 가로 세로비를 갖는 액정수지의 섬유를 갖어, 연신비 11-120으로 연신 처리함으로써 인장강도를 개선한다.
원하는 형태로 성형하기에는 직경이나 두께가 너무 작으로므 복합체를 다시 복수의 스트랜드나 필름소재를 서로 접합하여 성형 가능한 스트랜드나 시이트상으로 성형하는 형태의 합류공정, 접는 공정 또는 적층공정에 적용하는 것이 바람직하다.
