This invention relates to a method of preparing a hybrid composite laminate of layers of fiber reinforced material of different resin viscosities. The method comprises providing in a mould a first layer of a pre-impregnated material and a second layer.An uncured resin film is placed between the first and second layers.A resin of a second viscosity is provided to impregnate the second layer. The viscosity of the resin film is equal to or higher than the lowest viscosity of the first and second resins, whereby the resin migration between the fibrous layers during the resin impregnation may be controlled. The invention further relatesto acomposite laminate and a wind turbine blade component prepared by a method as mentioned above.The wind turbine blade may comprise a root part, a tip part, and an intermediate part therebetween, the intermediate part comprising a first layer of a pre-impregnated fiber reinforced material, and the root part comprising a second layer of fiber reinforced material. |
