摘要: A unidirectional reinforcement and a method of producing a unidirectional reinforcement for use in applications where high quality and strength is required. The unidirectional reinforcement includes transversely arranged thin discrete flow passage formed to ensure resin flow properties in a direction transverse to the direction of the unidirectional rovings. Thin discrete flow passage forming means are secured on the unidirectional rovings by means of additional yarns running on the thin discrete flow passage forming means and transverse thereto.

摘要: 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.

摘要: A method to produce a unidirectional reinforcement for fiber reinforced composites by a resin transfer or vacuum infusion molding process include: laying continuous rovings unidirectionally side by side in one layer for forming a unidirectional web, applying thermoplastic or thermoset binder on the web, activating the binder for bonding the rovings together to form a unidirectional reinforcement, and forming flow passages for resin in a direction transverse to the direction of the unidirectional rovings by laying thin discrete flow passage having, under compression, an aspect ratio of equal or less than 2 on the continuous unidirectional rovings.
