An apparatus for mounting a blind rivet, configured to mount the blind rivet having a rivet body and a mandrel on a board, may include a rivet holder accommodating a mandrel therein and pressing a rivet head towards the board, a mandrel holder positioned inside the rivet holder and moving separately from the rivet holder to hold and pull the accommodated mandrel, and an impactor positioned inside the rivet holder to accommodate the mandrel holder therein and applying pressure to the mandrel holder holding the mandrel, thus lifting the mandrel holder together with the mandrel.

A method for manufacturing of a part made of composite material including pre-compacting to a predetermined shape of a mixture of a first thermosetting resin with discontinuous long fibers so as to form a first preform, pre-curing the first preform until an intermediate conversion stage corresponding to a solidification of said first resin, contacting the first preform with a second preform including a fiber structure of continuous fibers impregnated with a second thermosetting resin, polymerizing the first and second preforms so as to form a part made of composite material including a body made of composite material including reinforcement made of continuous fibers consolidated by an organic matrix provided with a portion made of composite material including reinforcement made of discontinuous long fibers consolidated by an organic matrix.

Mechanically attaching articles made from composites has problems due to the difference in properties of the composite in the x, y planar direction and the z perpendicular direction, this results in different properties between the composite and the attachment member such as differences in coefficients of thermal expansion which can weaken the joint further leading to differences in moisture uptake which can further reduce the strength and robustness of the joint. The invention relates to the selection of the position of a joint in order to reduce such problems and to operating the moulding process in a way that improves the provision of mechanical attachments such as bolt holes.

An additional pad 27 is additionally and integrally arranged from an outer surface of a flange 17 opposite to a contacting side of the flange 17 to a small-diameter curved surface of a bend 19 and from there to an end of an outer surface of a part body 13. On an outer surface side of the additional pad 27, a fastening seat 27f is formed by machining. An area end PAe of a processed area PA formed by machining is positioned on the part body 13 beyond the bend 19.

A radome for housing a radar system comprises a plurality of interconnected curved radome thermoplastic composite material panels, each curved radome thermoplastic composite material panel having a plurality of interconnecting edges, a foam core, an inner skin, an outer skin, and a plurality of three-dimensional fiber bundles tying the inner skin and the outer skin to each other through the foam core, inhibiting delamination. The radome includes a hydrophobic exterior surface that is self-cleaning and requires zero maintenance for 25 years.

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.

Corner joints and methods of forming corner joints are described herein. The corner joints may provide the appearance of a mortise and tenon joint on both the exterior and interior surfaces of the corner joint, but include a mitered connection within the joint. Structures including at least one of the corner joints are also described.

In the present invention, a through-hole (2) and a compression periphery part (3a) at which the core of the resin foam (1c) is compressed are provided in a fastening part of a resin-foam core composite plate (1). A cylindrical part (11a) of a metallic fastening member (11) is inserted into the through-hole (2) from the proximal end side of a wall part (4). The fastening member (11) is crimped to the distal end of the wall part (4) via an eyelet member (12) placed on the outside of the wall part (4) so as to forcibly spread the cylindrical part (11a). The fastening member (11) and a counterpart member (A) are fastened together by tightening a nut (14) onto a bolt (13) inserted into the cylindrical part (11a).

Speed reduction gear comprising two intermediate transmission lines, in particular for a turbine engine, comprising an input line (12) and an output line that is driven by the input line via said intermediate transmission lines, said intermediate transmission lines being substantially parallel, characterised in that said reduction gear comprises means for distributing loads between said intermediate lines, said load distribution means comprising swiveling coupling means (30) for rotatably coupling one end of the input line, and oil-damping means (40, 50) for damping radial movements of an opposite end of the input line.

A process for joining fiber composite materials using self-piercing rivets. The process includes contacting first and second panels. The second panel is a fiber composite material. The process further includes elevating a temperature of only a fastening portion of the second panel. The process also includes placing the first and second panels on a die and joining the first and second panels with one or more rivets while the fastening portion is at an elevated temperature.
