A UNIDIRECTIONAL REINFORCEMENT, A METHOD OF PRODUCING A UNIDIRECTIONAL REINFORCEMENT AND THE USE THEREOF

摘要

The present invention relates to a unidirectional reinforcement and a method of producing a unidirectional reinforcement. The unidirectional reinforcement of the present invention may be used in all such applications where high quality and strength is required. The unidirectional reinforcement (20) of the invention comprises transversely arranged thin discrete flow passage forming means (40) for ensuring good resin flow properties in a direction transverse to the direction of the unidirectional rovings. The thin discrete flow passage forming means (40) are secured on the unidirectional rovings by means of additional yarns (42) running on the thin discrete flow passage forming (40) means and transverse thereto.
