    Abstract: A method for impregnating a fibrous material with a curable resin to form a prepreg (22) is disclosed. The method includes conveying a web material through at least one moving pressure nip formed between a moving pressure roller (54) and a moving supporting surface, wherein the moving pressure roller (54) and the moving supporting surface travel at different velocities relative to each other resulting in a relative velocity (vre|) between the web material and the pressure nip. The at least one moving pressure nip travels in the same direction as the web material while applying sufficient pressure to compress the web material and to affect impregnation of the fibrous material with the curable resin. Also disclosed is a system for implementing the disclosed impregnation method.
