Abstract
Official abstract text for this publication.
A method of producing a wind turbine rotor blade For that purpose metal particles, metal powder or metal chips are mixed into a matrix used to produce the rotor blade. Inductive heating of the matrix with the metal particles, metal powder or metal chips is then effected to harden the matrix in at least one portion of the wind turbine rotor blade.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method comprising: producing a wind turbine rotor blade comprising at least one of a glass fiber-reinforced plastic or carbon fiber-reinforced plastic bounded into a matrix, the producing comprising: mixing metal particles, metal powder, or metal chips into the matrix, and hardening the matrix in at least one portion of the wind turbine rotor blade by inductively heating the matrix with the metal particles, metal powder or metal chips, wherein a proportion of the metal powder, the metal particles, or the metal chips is between 5 and 20 percent by weight of the matrix. 2. The method according to claim 1 wherein the matrix with the metal particles, metal powder, or metal chips is provided at an end of a rotor blade, wherein the end of the rotor blade includes a rotor blade root, and wherein in a region of the rotor blade root, the matrix is exposed to an induction field generated by an induction coil so that the metal particles, metal powder or metal chips are inductively heated and transfer the heat to the matrix. 3. The method according to claim 1 wherein the wind turbine rotor blade has a first portion and a second portion, the second portion being arranged around the first portion, and wherein the matrix with the metal powder, the metal particles, or the metal chips is provided between the first and second portions. 4. The method according to claim 1 wherein the matrix has resin or epoxy resin.
