The present invention is provided with: an insulation holder formed of a thermoplastic resin material and having a first opening; a wire connection ring formed of a thermoplastic resin material and having a second opening; and a joining component inserted astride in the first opening and the second opening, the joining component being formed of a metal material having a higher melting point than those of the thermoplastic resin materials, the joining component having a higher stiffness than those of the insulation holder and the wire connection ring, wherein a welded part is formed by welding in at least a part of an area where each of the Insulation holder and the wire connection ring has contact with the joining component.

A tubular structure having lobes is produced as a single piece over at least two lobes. Circumferential fibres of the structure have a constant orientation with respect to the longitudinal axis (A) of the structure in any plane (P) transverse to the longitudinal axis. The structure is obtained by weaving or by filament winding.

A method of manufacturing a flywheel comprising: forming a first hollow cylinder from glass fibre composite with magnetic particles dispersed through at least part of the cylinder; curing said first cylinder in a first curing step; forming a second hollow cylinder from carbon fibre composite; and curing said second hollow cylinder in a second curing step.

An attachment for an end effector. The attachment may include a clamp and a foot adhesively bonded to an edge of the clamp and having a set of interlocking features that form a mechanical interlock with the clamp.

An engine cover system, includes a metal engine cover having an opening that receives a radial shaft seal including a seal lip adapted to engage a shaft, and a plastic film adhered to the metal cover over top of the radial shaft seal.

Described herein is a method of manufacturing a housing for the stator of an axial flux permanent magnet machine. The housing has a cylindrical wall including a metal outer ring lined with a polymer inner ring. The method includes positioning the metal outer ring in an injection moulding machine, and with the injection moulding machine injection moulding a polymer resin onto an inner surface of the metal outer ring to fabricate the polymer inner ring. The polymer inner ring includes a gripping surface arranged to grip a portion of the outer ring, for example moulded around a formation on an inner surface of the metal outer ring. The housing is manufactured using the metal outer ring and the polymer inner ring.

A fibrous preform of a turbomachine component has a three-dimensional weave formed by a plurality of woven strands, wherein, in a shear plane of the component, all or part of the strands present in this plane have fibers forming an angle between 10° and 50° with their centerline.

An additive manufacturing ink composition includes a polysiloxane bearing a plurality of alkenyl groups and a crosslinking agent bearing a plurality of thiol groups. The polysiloxane and the crosslinking agent form an emulsion.

A method of manufacturing an actuator The method comprises assembling the actuator, and curing the actuator using a predetermined heating profile.

A method and apparatus for building a fuselage assembly for an aircraft. A number of fixtures may be drive across a floor to an assembly area to form an assembly fixture. The fuselage assembly may be built on the assembly fixture.
