Beschreibung
Zusammenfassung:	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 of the invention comprises transversely arranged discrete Z-direction resin flow facilitating means (128) 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 (120). 本发明涉及单向增强体及制备单向增强体的方法。本发明的单向增强体可用于所有需要高质量和高强度的应用中。本发明的单向增强体包括横向布置的分立Z-方向树脂流动促进装置(128)，其在所述片材的所述纵向边缘之间来回延伸，并且在所述粗纱组之间及在所述单幅材(120)的所述顶表面和所述底表面之间行进。
