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.
