  • Method and apparatus for manufacturing fibre-reinforcing material
    Patent number: 5158806
    Abstract: A method for impregnating fibre bundles with molten or liquid resin in manufacturing a fibre-reinforced material, which material comprises one or more fibre bundles, wherein each fibre is surrounded by matrix resin, by impregnating a continuous web (10;10a) of one or more fibre bundles with molten or liquid resin (32, 33) and solidifying the resin by cooling or chemical reaction. During the impregnation the molten or liquid resin (35) material is made subject to shear forces by bringing it between two closely nearby surfaces (10;10a, 36;37) which are in moving relationship to each other.
    Type: Grant

  • Method and apparatus for manufacturing fibre-reinforcing material
    Patent number: 5108797
    Abstract: A method is disclosed for impregnating fibre bundles with molten or liquid resin (24, 29) in manufacturing a fibre-reinforced material, which material comprises fibre bundle or bundled groups of fibres, wherein each fibre is surrounded by matrix resin, by impregnating a continuous web (10, 10a) of one or more fibre bundles with molten or liquid resin (24, 29) and solidifying said resin by cooling or chemical reaction. Before said impregnation the molten or liquid resin material (29) is made subject to shear forces by bringing it to flow between two closely nearby surfaces (26, 27) which are in moving relationship into each other.
