An endless belt includes a band-shaped belt main body made of a vulcanized rubber, and a coupling part that is made of a thermoplastic resin and is provided between both end parts of the belt main body, wherein the vulcanized rubber of the both end parts of the belt main body and the thermoplastic resin of the coupling part are chemically bonded to each other.

A wing-box structure for an aircraft is disclosed having an upper cover, a lower cover, longitudinal forward and rearward spars, and a plurality of transverse ribs. One of the transverse ribs is retained by a pair of opposed captive features disposed on an interior side of either the forward and rearward spars or the upper and lower covers. The rib is bonded rib to the forward and rearward spars and/or the upper and lower covers at a location where the rib is retained.

A method is provided for joining thermoplastic components. During this method, a skin is provided that is configured from or otherwise includes a skin fiber-reinforced thermoplastic composite. A support member is provided that is configured from or otherwise includes a support member fiber-reinforced thermoplastic composite. A shim is arranged at an interface between the skin and the support member. The shim is configured from or otherwise includes a shim fiber-reinforced thermoplastic composite. The support member is welded to the skin through the shim at the interface.

The present invention provides a microchannel chip including: a resin substrate in which a channel groove is formed on at least one surface of the resin substrate; and a resin film which has a base layer and a pressure-sensitive adhesive layer and is bonded to the resin substrate such that the pressure-sensitive adhesive layer covers the channel groove, in which when a thickness of the base layer of the resin film is defined as X (μm), and a thickness of the pressure-sensitive adhesive layer of the resin film is defined as Y (μm), all of Relational Expressions (1) to (3) are satisfied.

A method for joining two substantially planar fiber-composite structural components, includes stacking the two components on a support jig to overlap along a joining region. A lower component end section within the joining region borders a gap between the upper component and the jig, where the upper component is unsupported by the jig. The gap is bordered on an opposite side of the lower component end section by a filling portion of the upper component or a planar filler element supported by the jig. The lower component is joined to the upper component within the joining region by applying temperature and pressure to the components. A width of the gap allows the upper component to elastically deform along the gap under the pressure and bend down into the gap to abut the jig along the gap and thereby compensate thickness tolerances between the components during the pressure application.

A method of joining segments of non-metallic pipe and an apparatus that may be used to form the joint. The pipes may be joined using by melting the ends to form a butt joint, then the joint may be wrapped with one or more sheets of reinforcement material (e.g., pre-impregnated fiberglass, carbon fiber, or aramid fiber). The reinforcement material may be heated using a heating apparatus which allows the material to bond to the pipes to strengthen the joint.

A method for assembling two parts, referred to as first and second parts, the first part being produced from composite material with fibrous reinforcement embedded in a thermosetting or thermoplastic matrix, the method comprising the steps of: obtaining the first part comprising, on all or part of an outer surface, a first amorphous thermoplastic film; positioning the first part and the second part such that the first amorphous thermoplastic film is placed opposite the second part; introducing a thermosetting resin between the first amorphous thermoplastic film and the second part; at least partially polymerising the thermosetting resin. When the two parts comprise an amorphous thermoplastic film, the parts are positioned such that the respective amorphous thermoplastic films are placed opposite each other, and the thermosetting resin is introduced between the amorphous thermoplastic films.

A lightweight, flame-retardant, multilayered composite structure having at least the following components: a thermoplastic foam core having two opposing surfaces; a thermoplastic adhesive film on at least one of the opposing surfaces of the foam core, one or more composite layer(s) on each adhesive film. The composite layer(s) is/are composed of reinforcement fibers embedded in a thermoplastic polymer or thermoset resin matrix. Adhesive bonding is effectuated by the interleaving thermoplastic adhesive film interposed between the thermoplastic foam core and the adjacent composite layer. The thermoplastic adhesive film is formed of a thermoplastic polymer composition having a T.sub.g of at least 20° C. lower than the T.sub.g of the foam core material.

A process for thermo-adhesive bonding of semi-finished products includes preparing an inner sock, an outer sock and an impermeable membrane provided with a thermo-adhesive disposed on an inner surface and/or an outer surface of the membrane; fitting the inner sock onto a rigid reference shape; fitting the membrane over the inner sock; fitting the outer sock over the membrane; heating the outer sock, the membrane and the inner sock arranged on the rigid reference shape in an oven until at least partial melting of the thermo-adhesive; cooling the outer sock, the membrane and the inner sock arranged on the rigid reference shape until cross-linking of the thermo-adhesive and stable bonding of the membrane to the outer sock and/or the inner sock. Also, exerting a substantially uniform pressure on the outer sock, the membrane and the inner sock disposed on the rigid reference shape during cooling, so as to compact them.

A method for fusing thermoplastic composite structures includes placing a substructure on an inner surface of a skin that is laid up on a shaping surface of a tool configured to maintain the shape of an outer mold line. The method further includes applying at least one insulation layer over a flange of the substructure and over exposed portions of the inner surface of the skin not in contact with the substructure, and applying a vacuum bag to at least partly enclose the skin and the substructure. The method yet still further includes applying heat to the shaping surface to fuse the substructure to the skin such that the skin exceeds its melting point and at least a portion of a raised segment of the substructure does not exceed its melting point.
