Abstract: Provided is a wind turbine blade, with a generally hollow blade body including half shells and webs the webs including flanges connecting the respective web to the respective half shell, and with webs being supported via reinforcement structures relative to the respective half shell, which reinforcement structures are arranged between an outer and an inner layer of each half shell and extend in the lengthwise direction of the blade, whereby the reinforcement structures each include at least one stack composed of several glass fiber layers infused with resin, and that at least one stiffening element extending parallel to the first and second reinforcement structures over at least a part of their length including at least one stack composed of several pultruded composite strips including carbon fibers with the strips being fixed in the resin is arranged between the first and second reinforcement structures.

Abstract: Provided is a turbine blade, including shells and webs connected to the shells, with, with each web being supported by reinforcement structures, whereby a first reinforcement structures includes at least one stack composed of several pultruded composite strips including carbon fibers with the strips being fixed in a resin matrix, and a second reinforcement structures supporting a second web either include at least one stack composed of glass and/or carbon fiber layers infused with resin, the stack being disposed between an outer and an inner layer of upper and lower shell, or at least one stack composed of glass and/or carbon fiber layers infused with resin or of several pultruded composite strips including carbon fibers with the strips being fixed in a resin matrix, which stack is an integral part of the second web and builds the flange.
