A composite structure (10) comprising one or more electrically conductive pathways (12) and one or more isolators for isolating the pathways (12) from the bulk of the structure (10).

A lightning strike protection layer for an aircraft is disclosed having a first portion and a second portion, the first portion includes a first fibre reinforced polymer composite layer and a first electrically conductive metal layer and the second portion includes a second fibre reinforced polymer composite layer and a second electrically conductive metal layer, and the first and second portions are joined at a butt joint, with the first and second fibre reinforced polymer composite layers abutting and the first and second electrically conductive metal layers abutting; and a butt-strap extending across the butt joint, the butt-strap comprising a third electrically conductive metal layer electrically connected to the first and second electrically conductive metal layers.

The heat exchanger includes at least one tube array in which refrigerant flows, the tube array includes a plurality of tubes each having a channel formed therein, and connection members coupled to opposite ends of the tubes so as to interconnect the tubes, and the tubes are injection molded integrally with the connection members.

A fire-resistant bus bar includes a bus bar conductor part; a sheath layer of a fire-resistant silicone, and a protective layer. The sheath layer covers portions of the bus bar conductor part excluding both ends and is ceramicized at high temperatures to support the bus bar conductor part. The protective layer covers the sheath layer, in which a metal sheet is included in the sheath layer to reinforce the structural rigidity of the sheath layer. A battery pack and method of manufacture are also provided.

The present invention relates to a metal member and a manufacturing method therefor, an etching solution, and a metal-resin complex and a manufacturing method for the metal-resin complex. The metal member has a surface in which values of L, a and b in CIE1976 (L*a*b*) color space satisfy at least one of equation (1) (b16) or equation (2) (L2.3368-2.0536).

A formation method is provided during which a lightning strike protection and thermoplastic material are arranged on a tool. The lightning strike protection includes a plurality of interconnected conductive elements. A thermoplastic composite structure is arranged over the lightning strike protection and the thermoplastic material with the lightning strike protection and the thermoplastic material between the tool and the thermoplastic composite structure. The tool is heated to provide a heated tool. The thermoplastic material is heated using the heated tool to melt the thermoplastic material and bond the lightning strike protection layer to the thermoplastic composite structure.

The present invention pertains to a rectangular wire including: a rectangular conductor; and a film of an insulating coating material that directly covers the entire circumferential direction of the rectangular conductor, wherein: a melt flow rate of the insulating coating material at a temperature of 372 C. and a load of 49 N is from 20.0 to 300.0 g/10 min; the insulating coating material contains polyaryletherketone (A) and a fluorine-containing copolymer (B) having a unit based on tetrafluoroethylene; an amount of the fluorine-containing copolymer (B) with respect to a total mass of the polyaryletherketone (A) and the fluorine-containing copolymer (B) in the insulating coating material is 5% by mass or more; and the rectangular wire is such that the film of the insulating coating material does not peel off from the rectangular conductor in a winding test conforming to JIS3216-3:2011 5.1.2 Rectangular Wire.
