The invention relates to a method of manufacturing a shell part (101) for a wind turbine blade also comprising an add-on component (301, 302) connected to the shell part (101) along a connection face. The method comprises the steps of providing an insert (102) with a side surface of approximately the same shape as the connection face, positioning the insert in an open mould, and placing one or more layers (105) of material in the mould (103) to form the shell part (101) wherein the layers (105) are placed in abutment to the side surface (104) of the insert (102) thereby forming a side surface (108) of the shell part (101) of approximately the same shape as the connection face. After resin cure, the insert (102) is removed. The invention further relates to a method of manufacturing a wind turbine blade shell member (100) comprising such a shell part (101), and layers (105) of material are placed in the mould (103) in abutment to the side surface (108) of the shell part (101) to form the add-on component (301, 302).

A hinged component includes first and second portions of material coupled together by a composite live hinge. The live hinge includes a layer of tensile fabric and a layer of elastomer interposed between the tensile fabric and the material of one or both of the coupled first and second portions. The composite live hinge is capable of joining structural composite materials without the need for scoring, and thereby weakening, the structural composite material along the desired hinge line. The live hinge can be embedded in the materials it joins in a method that is compatible with traditional structural composite layup processes and in a manner which prevents resin from the structural composite materials from infiltrating the tensile fabric and compromising its flexibility.

The method comprises the steps of providing an insert with a side surface of approximately the same shape as the connection face, positioning the insert in an open mould, and placing one or more layers of material in the mould to form the shell part wherein the layers are placed in abutment to the side surface of the insert thereby forming a side surface of the shell part of approximately the same shape as the connection face. After resin cure, the insert is removed. The invention further relates to a method of manufacturing a wind turbine blade shell member comprising such a shell part, and layers of material are placed in the mould in abutment to the side surface of the shell part to form the add-on component.
摘要:
A method of forming a structural tube may include urging a substantially flat thermoplastic sandwich sheet against a mandrel and heating the thermoplastic sandwich sheet to a temperature below a glass transition temperature. The method may further include allowing the thermoplastic sandwich sheet to cool and removing the mandrel, thereby forming a tube portion.

A composite component coupling system, comprising a composite component (10, 10') built up of a plurality of layers, wherein the plurality of layers define a thickness of the composite component in a direction perpendicular to the layer plane, is characterized by a closure piece (20') for bearing against a side of the composite component at which all the layers are exposed, the maximum thickness of which does not exceed or only insignificantly exceeds the thickness of the composite component and which terminates flush with the outwardly pointing surface of at least one outer layer, wherein the bearing side of the closure piece (20') is at least partially bevelled, and the bevel (22'), when bearing against the composite component, covers at least one of the outer layers of the composite component which comprise thermoplastic material, wherein the composite component has a contouring which corresponds to the contour of the bearing side of the closure piece.
摘要:
A traditional intercooler comprises a plurality of tubes and a pair of tube plates to secure and align the tubes. Each end of each tube must be attached and sealed which can be time consuming and expensive. An intercooler assembly (26) is provided and includes a housing (42) that defines an internal space (50) containing a plurality of tubes (52). A joint between a tube and a tube plate (54, 56) is created by a laser welding process. A form (196) presses the walls of the tube outwardly to form the flange (186). The downward force of the form (196) not only creates the desired flange (186), but also exerts a pressure that holds the flange (186) against the tube plate (54, 56). The form (196) provides for the transmission of laser energy so that the creation of the flange (186) can be performed concurrently with the welding process.
