US Patent 7625185 Bearing structure

The present invention concerns a bearing structure for a composite structure rotor blade having fiber strands which extend along the length of the rotor blade. Prefabricated, stiff components are provided in the composite structure. The invention further concerns a process for the production of a shaped body, in particular a rotor blade, of a fiber composite structure, comprising the following steps: producing shells forming the outer contour of the shaped body, producing bearing structures of fiber strands of predetermined length which are impregnated with a hardening composite material, and transporting the bearing structure into the shells. Therefore the object of the present invention is to develop a process of the above-defined kind in such a way that the exothermic reaction is restricted and the risk of undulations is reduced.
