Abstract

본 발명은 상술한 액정수지를 사용한 복합체를 사출성형하는 경우에 그 사출성형의 전단속도를 어떤 영역에 설정하므로서 사출 성형의 결점인 섬유의 분단을 보충하는 것을 목적으로 하는 것으로서, 액정수지의 액정저니온도 보다도 낮은 최저성형 가능 온도를 갖는 매트릭스 수지중에 액정수지가 섬유형상으로 존재하는 성형용 펠릿을 사용해서 상기한 액정 전이온도와 매트릭스 수지의 최저성형가능온도와의 사이의 온도 범위내에서 사출 성형하는 방법으로서 사출통내에 있어서의 수지에 작용하는 최대전단 속도를 15,000sec-1이하로 설정하는 것을 특징으로 하는 사출성형방법 그로 부터 얻어진 성형물품을 제공하는 것이다.
