  • Unidirectional reinforcement, a method of producing a reinforcement and the use thereof
    Patent number: 10035301
    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.
    Type: Grant
    Filed: August 30, 2016
    Date of Patent: July 31, 2018
    Assignee: Ahlstrom-Munksjo Oyj
    Inventors: Rainer Bergstrom, Ulla Kosonen, Rami Haakana, Maija Hoikkanen
  • Unidirectional reinforcement, a method of producing a unidirectional reinforcement and the use thereof
    Patent number: 10022907
    Abstract: 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.
