The invention concerns a device (1) for the coating of workpieces (2) which preferably consist, at least in sections, of wood, wooden materials, plastics, aluminium or the like, comprising: a feed means (10) for feeding a coating material (12), a pressing means (20) for pressing the coating material (12) onto a surface (2a) of a workpiece (2), a conveyor means (4) for causing a relative motion between the pressing means (20) and the respective workpiece (2), and a first joining means (30; 50) for applying and/or activating an adhesive agent on a coating material (12) fed by the feed means (10) and/or a surface to be coated of the workpiece (2), characterized in that the device further comprises at least a second joining means (40; 60) for applying and/or activating an adhesive agent on a coating material (12) fed by the feed means (10) and/or a surface to be coated of a workpiece (2).

A composite material of particles disposed in a matrix material is provided in which the particles have an asymmetric geometric shape with a longest dimension and a shortest dimension different from the longest dimension. Adjacent volume portions of the composite material are arranged in a mosaic pattern to abut along an interface or surface forming a common boundary between the adjacent volume portions. The particles within the adjacent volume portions are arranged with differing orientations with respect to the interface. The orientations of the particles in the adjacent volume portions are selected so that a crack propagating on a crack propagation path through one or the other of the adjacent volume portions stops at or deflects to propagate along the interface. Methods of making composite materials are also provided.

A method for manufacturing a high-pressure tank includes: forming a preform by winding a carbon fiber around a liner to form a fiber layer on an outer periphery of the liner, and impregnating the fiber layer of the preform with a curable resin and curing the curable resin. When winding the carbon fiber around the liner, a metal wire together with the carbon fiber is wound around the liner.

A method is provided during which a thermoplastic rib is arranged with a thermoplastic spar. A first flange of the thermoplastic rib is abutted against the thermoplastic spar. The first flange of the thermoplastic rib is ultrasonic welded to the thermoplastic spar using a tilted ultrasonic horn. A centerline of the tilted ultrasonic horn is angularly offset from the first flange of the thermoplastic rib by an acute angle during the ultrasonic welding.
