Abstract

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).
