Abstract: The present invention relates to fiber-plastics composites consisting of (I) at least one fiber material and (II) a plastics matrix, where the composite is characterized in that the plastics matrix is based on a two-component matrix material (IIa), where the two-component matrix material (IIa) comprises (1) a parent component comprising (A) at least one polycarbonatediol and (2) a hardener component comprising (C) at least one polyisocyanate-modified polyester with from 4 to 15% isocyanate content. The present invention also relates to a process for the production of the fiber-plastics composites and to use of these.

Abstract: A wind turbine blade includes an upper shell member and a lower shell member joined at leading and trailing edges of the blade with a bond material. Portions of the bond material are externally exposed. The bond material has surface characteristics of at least one of a Shore D hardness value of greater than about 80 durometer or a Young's modulus stiffness value of greater than about 5 GPa. A protective coating is applied over the upper and lower shell members and exposed portions of the bond material.

Abstract: A method and associated system are provided for bonding component parts of a wind turbine blade along a bond line. A barrier is placed within an internal cavity of the blade at a defined bond line width along the length of the bond line. A plurality of spaced apart external access ports are defined along the bond line into the internal cavity. A bond paste is sequentially injected into the plurality of access ports to fill the bond line.

Abstract: A method for utilizing an infusion mesh for producing a curved rotor blade for a wind turbine rotor is provided. The method includes providing an infusion mesh including a polymer; placing the mesh into a curved mold and arranging the mesh to have the curved shape of the mold, and applying thermal energy to at least parts of the infusion mesh, so that at least parts of the mesh are heated to a melting temperature of the polymer material.

Abstract: A method for forming a fiber-reinforced plastic part is provided. The method includes providing a mold, providing a vibration generator, placing a fiber material in the mold, infusing the fiber material with a resin while the fiber material and/or the resin are exposed to vibrations, and curing the resin.

Abstract: A method of forming a wind turbine blade includes forming a fiber-reinforced resin body. The fiber-reinforced resin body includes a fiber-resin matrix formed with, at least partially, at least one of at least one resin/additive mixture produced by mixing at least one first opaque additive within a first quantity of resin and a first layer of fibers having a plurality of pigmented fibers. The pigmented fibers are formed by at least one of impregnating at least a portion of the first layer of fibers with at least one second opaque additive and forming at least one layer of opaque coating over at least a portion of the first layer of fibers. The opaque coating has a third opaque additive.
