Process for the production of a fiber-reinforced composite material

A process for producing a fiber-reinforced composite material with a polyamide matrix by

• a) providing a solid polymerizable composition which comprises
• A) at least one lactam,
• B) at least one catalyst, and
• C) at least one activator selected from isocyanates, anhydrides, acyl halides, reaction products of these with A), and mixtures of these,
• b) applying, in solid, free-flowing form, the polymerizable composition provided in step a) onto a fiber material,
• c) subjecting the fiber material obtained in step b) with the applied polymerizable composition to treatment at elevated pressure and at a temperature at which the mixture of components A), B), and C) is flowable, where this encloses and penetrates the fiber material,
• d) cooling the product obtained in step c).
