rotor blade or rotor blade element for a wind power installation, wind power installation, process for producing a rotor blade or rotor blade element, and repair process for a rotor blade element a wind power installation

摘要

The rotor blade or rotor blade element comprises a surface film, which is reacted with a hardenable resin for forming a rotor blade and/or rotor blade elements. A fiber material is soaked with the hardenable resin. The rotor blade or rotor blade element is a web, a rotor blade outer jacket and its part such as half-shell of pressure side or suction side, a rotor blade leading edge, a rotor blade trailing edge, a rotor blade tip, a spar cap, a flange reinforcement, an internal reinforcement for slinging equipment, a ballast chamber, and a balancing chamber.

The rotor blade outer jacket has a length of 3-60 m and a width of 0.2-7 m, and the web has a length of 1-50 m and width of 0.05-7 m. The surface film has an area of 0.005-500 m 2, an average thickness of 50-1000 mu m and an effective thickness of 10-1000 mu m. The surface film is a deep-drawn film. The surface film is a polymer film. The resin is reactive resin and an epoxide resin. The surface film is equipped its side turned away from the fiber material with a demolding coating. An independent claim is included for a method for the production of rotor blade or rotor blade element.
