A connector body having a first end portion defining a first end face of the body and an opposite second end portion defining a second end face of the body, the first end portion including a first peripheral groove with a first sealing ring, and the second end portion including a second peripheral groove with a second sealing ring, an intermediate portion of the—body defining a peripheral surface extending between the first sealing ring and the second sealing ring, the peripheral surface to be covered by the retaining glue for bonding the body to the tube, a glue flow passage at the first end portion extending transversally to the first sealing ring, and a glue injection channel extending from the first end portion towards the second end portion and including a glue injection port in the first end portion and a glue ejection port at the peripheral surface.

A composite vehicle driveshaft assembly includes a composite tube and a yoke bonded to one of the ends of the tube. The yoke has an inner sleeve that is concentrically received in the end of the tube. The sleeve has an outer peripheral surface that faces the inner peripheral surface of the tube with a cavity formed therebetween. An adhesive injection passage is formed in the yoke and extends at an acute angle from an inlet that is formed in an axial surface of the yoke to an outlet that is formed in the outer peripheral surface of the sleeve and that opens into the cavity. Also disclosed is a method of bonding a yoke of such a driveshaft assembly to a composite tube.

An optical element includes an optical material including a first edge and an opposing second edge. The optical element further includes a plurality of micro-channels arranged within the optical material. Each of the micro-channels of the plurality of micro-channels extends from the first edge to the second edge of the optical material.

A method of forming a pipe joint between a pipe section and a pipe fitting includes inserting an end of the pipe section into a socket of the pipe fitting, and attaching a removable clamp to the pipe section and pipe fitting. The socket includes a centering device and a pipe stop that is configured to receive the end of the pipe section. The clamp includes a plurality of arcuate segments and a tightening mechanism, and each arcuate member has a removable/replaceable sealing member. The arcuate members are radially compressed via the tightening mechanism to cause the respective sealing members to seal an open end of the gap. A bonding agent is then injected into the gap via a port that extends through the pipe fitting. Once the bonding agent has been injected, the clamp is removed and can be reused.

A method for manufacturing a structural element of a wind turbine blade including forming of at least one injection hole in at least one laminate provided on a top side of a core material of a first portion and a second portion of the structural element and a bottom side of a core material of the first portion and the second portion, so that the at least one injection hole is fluidically connected to the cavity. Further, injecting adhesive through the injection hole into the cavity, curing the adhesive injected into the cavity and thereby forming a joint between an end of the core material of the first portion and an end of the core material of the second portion. Further, a method for manufacturing a wind turbine blade and the structural element, the wind turbine blade is also provided.

A method of forming a dielectric barrier and torque transfer member between a drive shaft and a driven shaft of a torque transfer assembly. The method includes assembling the drive shaft and the driven shaft in axially adjacent relationship to one another, the drive shaft and the driven shaft each having a recess formed therein such that when the shafts are assembled, the recesses cooperate to define a chamber extending across the interface between the drive and driven shaft and into the interior of both the drive and the driven shaft. The method further includes injecting a dielectric adhesive or resin material into the chamber to fill the chamber and to extend across the interface between the drive and the driven shaft, and curing the dielectric material to form a dielectric barrier between and to provide torque transfer between the drive and the driven shaft.

The invention concerns a method for joining a metal component and a polymer component, and a structure comprising said components. In the method, an extrusion die plate with a through hole is placed between the metal component and the polymer component. A probe is rotated and plunged across the thickness of the metal component and eventually through said through hole of the extrusion die plate, thereby extruding a part of the metal component through said through hole of the extrusion die plate into the polymer component. The probe has a rotation axis having an offset to the centre of the through hole during the rotating and plunging action.
