The invention relates to a process for the production of finished parts made of at least one multilayer, fiber-reinforced, flat semifinished-product structure, comprising the following steps:

Process for the production of finished parts

The invention relates to a method for producing a composite plastic part (CK). A first fiber material (F) is impregnated with a polyamide matrix polymer (PAM), thereby obtaining a matrix composition (MZ), onto which a surface composition (OZ) is applied, and a first plastic component (K) is obtained. In a second step, a second plastic component (K) is molded on the first plastic component (K), whereby the composite plastic part (CK) is obtained. The invention further relates to the composite plastic part (CK) which can be obtained using the method according to the invention. The invention additionally relates to the use of polyethyleneimine (PEI) for improving the impregnation of the first fiber material (F) with the polyamide matrix polymer (PAM).

Method for producing a composite plastic part (CK)

A process for producing an activated monomer composition comprising at least one lactam and/or lactone, one catalyst, and one activator permits storage of the resultant monomer composition, since this is stable with respect to polymerization. Said monomer composition is used inter alia in producing a polyamide molding via ring-opening, anionic polymerization.

Process for producing monomer compositions and use of these for producing a polyamide molding

The present invention relates to a plastic composite component (CC) which has a first plastic component (C1) and a second plastic component (C2) and comprises a polyethyleneimine (PEI) for improving the adhesion between C1 and C2. The present invention further relates to a process for producing this plastic composite component (CC), to a process for improving the adhesion between a first plastic component (C1) and a second plastic component (C2) in a plastic composite component (CC) and to the use of polyethyleneimine for improving the adhesion between a first plastic component (C1) and a second plastic component (C2) in a plastic composite component (CC).

Composite plastic part with improved adhesion between the plastic components contained in the composite plastic part

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).

Composite plastic part with improved resistance to heat aging

The present invention relates to a process for preparing a composition comprising (A) at least one lactam, (B) at least one catalyst, (C) an activator from the group consisting of isocyanates, acid anhydrides, acyl halides, reaction products thereof with (A) and mixtures thereof, (D) at least one polyethyleneimine. The invention likewise relates to a composition comprising (i) 0.01 to 10 wt %, based on the sum total of components (A) and (D), of at least one polyethyleneimine, and (ii) 90 to 99.99 wt %, based on the sum total of components (A) and (D), of at least one lactam (A) and/or polyamide obtainable from (A).

Use of polyethyleneimines in the preparation of polyamides

The present invention relates to a process for producing polyamides, preferably crosslinked polyamides, via anionic polymerization of lactams in the presence of an anionic catalyst and of a caprolactam-capped polyisocyanate, where said isocyanate comprises more than 3.5 capped isocyanate groups.

Process for producing polyamides via anionic polymerization

The invention relates to a process for producing fiber-reinforced flat semifinished products based on a polyamide matrix, comprising the following steps: The invention further relates to a process for producing a component made of the fiber-reinforced flat semifinished product.
