ROTOR BLADE ELEMENT FOR A WIND TURBINE, ROTOR BLADE AND A PRODUCTION PROCESS THEREFOR AND WIND TURBINE WITH ROTOR BLADE Russian patent published in 2018 - IPC F03D1/06 B32B25/08 B32B27/32 

FIELD: hydraulic machines and engines.

SUBSTANCE: invention relates to an element of a rotor blade for a wind power plant, a rotor blade of a wind power plant, and to a method for manufacturing a blade of a wind power plant. Rotor blade element of the wind power plant, in particular the edge of the rotor blade, for a wind power plant, including a base comprising a fibrous material impregnated with a curable resin, and a surface film with a fastening layer located between the base and the surface film, the surface film comprising ultra-high molecular weight polyethylene (UHMW-PE). Fastening layer includes a first rubber layer and a second rubber layer, the first rubber layer being intended for a surface film, and the second rubber layer is intended for a base, the degree of vulcanization of the first rubber layer being higher than the degree of vulcanization of the second rubber layer.

EFFECT: invention is aimed at increasing the abrasion strength of the blades of the rotor blades of the wind power plant.
