A propeller blade (100) includes a foam core (104) and a structural layer (106) that surrounds at least a portion of the foam core (104) and includes a face side (107) and a camber side (109). The propeller blade (100) also includes an insert (105) disposed in the foam core (104) in operable contact with the face side (107) and the camber side (109) of the structural layer (106).
摘要:
A method for bonding a first and a second prefabricated parts of a wind turbine blade comprising the steps of: disposing bands (45, 55, 65) of an adhesive material in a manageable uncured state following traces (43, 53, 63) signaled on a bonding area of one of said parts, said adhesive material being able to flow in a curing stage in a controlled way, the width (W) and height (H) of said bands (45, 55, 65) and the separation (S1) between said traces (43, 53, 63) being determined so that a predetermined separation (S2) between said bands (45, 55, 65) comprised between 0-300 mm remains after the bonding; bonding both parts under predetermined conditions of pressure and temperature. The invention also refers to a wind turbine blade having prefabricated parts bonded using said method.
摘要:
An intermediate-manufactured composite airfoil (10) includes first and second composite skins (12,14) each having a plurality of fibers (16) in a polymer matrix (18). A composite core (20) is removably located between the first and second composite skins (12,14). The composite core (20) includes a dry, three-dimensional, woven fiber network (22) or, alternatively, a three-dimensional, woven fiber network (22) in a fully cured polymer matrix (24).
摘要:
A method of manufacturing a wind turbine blade shell part comprising fibre material impregnated with cured resin is described. The method comprises the steps of : a) providing a first mould part (110) having a first forming surface (112) with a contour that defines at least a part of an outer surface of turbine blade shell part, b) arranging fibre material in the first mould part, the fibre material comprising fibres of a magnetisable material, c) providing a resin in the first mould part simultaneous with and/or subsequent to step b), and d) curing the resin in order to form the wind turbine blade shell part or wind turbine blade (150). The fibre material is retained against the first forming surface by use of magnet means (114, 116, 118) during step b) and/or step c). A mould part comprising magnet means (114, 116, 118) and a wind turbine blade are also described.
摘要:
The invention relates to a method for producing a rotor blade for a wind energy plant, which, in the operationally -ready state runs from a blade root region, for connecting to the rotor hub of the wind energy plant, to a blade tip and is divided into at least two pieces for production thereof. According to the invention, the production of the rotor blade, in particular serial production, may be facilitated and accelerated, wherein the rotor blade is segmented into more than two segments for production, at least for some of said segments, separate moulds for simultaneous separate use are provided and the segments for final production of the rotor blade are joined outside a production mould to give a rotor blade or rotor blade part.
