摘要:
The present invention relates to a method for manufacturing a turbine blade (1) for a wind turbine. The method comprises: - Manufacturing a first turbine blade part (2), - Manufacturing a second turbine blade part (4), - Aligning the first turbine blade part (2) with the second turbine blade part (4), and - bonding the first turbine blade part (2) to the second turbine blade part (4) along the bonding line (6) in a thermoplastic welding process with a thermoplastic resin. The invention also relates to a Turbine blade (1) for a wind turbine.
摘要:
A method of resistive implant welding thermoplastic composites. At least two sections of a component formed with weldable thermoplastic material are provided. The two sections of the component each have a welding surface along which the component is welded together. The welding surface includes a first surface adjoining a second surface at an angle exceeding about 30 degrees or another three dimensional shape. A first wire mesh conductor material is positioned between the welding surface of the at least two sections along the first surface. A second wire mesh conductor material is positioned between the welding surface of the at least two sections along the second surface in an overlapping manner at the angled connection. An electric current is applied to the conductors causing the conductors to heat up and melt the at least two sections of the component together.

A method for installation and repair of insulated piping includes placing a sleeve coupling, made of a weldable polymer material incorporating a slit that runs lengthwise along the piping, and whose length exceeds the distance between the outer pipes' ends, over the exposed section of the inner pipe so as to overlap the ends of the outer pipes, and welding the sleeve coupling to the outer pipe at the ends of the outer pipes, by placing an electrically conductive band between the outer pipe and the sleeve coupling, ensuring that free ends of the band project upward through the slit. A power converter which has a quasi-resonant converter is employed to produce the electric current that is to be connected to the band.

A method of reinforcing a vehicle seat structural member may include identifying a reinforcement region (38) of the vehicle seat structural member based on an area of the vehicle seat structural member that will be subjected to higher operational stress than another area of the vehicle seat structural member and attaching a reinforcement member (40; 140; 240; 340) to the reinforcement region (38) of the vehicle seat structural member. The reinforcement member (40; 140; 240; 340) may include at least one of structural epoxy (42), a plastic (140), a metallic member (240), and a composite member (46). The reinforcement member (40; 140; 240; 340) may be configured to reinforce the vehicle seat structural member in the reinforcement region (38).
