20110097211 | WIND TURBINE BLADE - A wind turbine blade is disclosed, at least 50% of the surface of which is covered with a self-adhesive, thermoplastic film. A method of manufacturing and repairing such a wind turbine blade is also disclosed. A two layer thermoplastic film suitable for covering the surface of a wind turbine blade is also disclosed. The film comprises a surface layer and a lower layer. The surface layer comprises 50% to 85% of polyvinylidene fluoride (PVDF), wherein up to 30% of the polyvinylidene fluoride may be replaced by hexafluoropropylene (HFP); and 10% to 45% polymethyl methacrylate (PMMA). The lower layer comprises 10% to 45% of a polyvinylidene fluoride (PVDF) polymer, wherein up to 30% of the polyvinylidene fluoride may be replaced by hexafluoropropylene (HFP); and 50% to 85% PMMA. Optionally the surface and/or lower layer comprises up to 8% UV stabilisers/absorbers; up to 10% matting agent; and up to 40% of an inorganic pigment. The film has an initial gloss of less than 30% when measured with a reflectometer at a angle of 60 degrees. | 04-28-2011 |

20090246033 | WIND TURBINE BLADE - There is provided a wind turbine blade at least 50% of the surface of which is covered with a self-adhesive thermoplastic film. By applying a self-adhesive thermoplastic film to the blade, the need for a gelcoat or the paint is eliminated. It is estimated that the thermoplastic film will take a similar time to apply as the gelcoat and/or paint. However, it does not require any further treatment once it has been applied thereby reducing significantly the work involved in finishing the blade. Also, the thickness of the film is precisely controlled in advance of its application to the blade ensuring that a surface with a uniform thickness is produced. | 10-01-2009 |
