Abstract
A method of making a composite of a unidirectional fibrous web in a polymer matrix composition by nonuniformly feeding a polymer composition into contact with a unidirectional fibrous web into a gap between two adjacent compression surfaces with at least one of the surfaces having a pattern. This results in the polymer becoming nonuniformly distributed into thick areas and thin areas as a matrix for the fibrous web.
