본 발명은 제1 섬유 재료(F1)가 폴리아미드 매트릭스 중합체(PAM)에 의해 함침되어 매트릭스 조성물(MC)이 얻어지고, 이에 표면 조성물(SC)이 도포되어 제1 플라스틱 성분(C1)이 얻어지는 플라스틱 복합 부품(CC)의 제조 공정에 관한 것이다. 제2 단계에서, 제2 플라스틱 성분(C2)이 제1 플라스틱 성분(C1) 상으로 성형되어 플라스틱 복합 부품(CC)이 생성된다. 또한, 본 발명은 본 발명의 공정에 의해 얻어질 수 있는 플라스틱 복합 부품(CC)에 관한 것이다. 또한, 본 발명은 폴리아미드 매트릭스 중합체(PAM)에 의한 제1 섬유 재료(F1)의 함침을 개선하기 위한 폴리에틸렌이민(PEI)의 용도를 제공한다. The present invention relates to a process for producing a plastic composite component (CC) in which a first fiber material (F1) is impregnated with a polyamide matrix polymer (PAM) to obtain a matrix composition (MC), to which a surface composition (SC) is applied, and a first plastic component (C1) is obtained. In a second step, a second plastic component (C2) is molded onto the first plastic component (C1), giving the plastic composite component (CC). The invention further relates to the plastic composite component (CC) obtainable by the process of the invention. The present invention further provides for the use of polyethyleneimine (PEI) for improving the impregnation of the first fiber material (F1) with the polyamide matrix polymer (PAM).
