Patent ID: 8157939

Claim:
A method for manufacturing a fibre reinforced laminate, comprising: providing one or more wrinkle preventing layers, each wrinkle preventing layer being produced by partly impregnating a layer of fibre material with resin in such a way that the resin forms spaced stripes continuing along a first lateral direction and curing the resin to provide a desired level of stiffness in the first lateral direction which is greater than a stiffness in a second lateral direction of the wrinkle preventing layer; building up a first part of the laminate to a first thickness using at least one layer of fibre material; placing a wrinkle preventing layer against the first part of the laminate; further building up the laminate using at least one additional layer of fibre material after the step of placing a wrinkle preventing layer; and repeating the placing and further building steps until the thickness of the laminate is equal to a desired thickness of a completed laminate.
