Abstract
A unidirectional reinforcement and a method of producing a unidirectional reinforcement that may be used in applications where high quality and strength is required. The unidirectional reinforcement includes transversely arranged discrete Z-direction resin flow facilitating means running back and forth between the longitudinal edges of the sheets, and traveling between the groups of rovings and between the top and bottom surfaces of the unitary web.
