This invention describes a 3-layer insulation material (10) comprising a first fabric layer (12), a second fabric layer (14) and a third fluted intermediate fabric layer (16) between the first and the second fabric layers (12, 14), the fluted intermediate fabric layer (16) being attached alternately to the first and the second fabric layer (12, 14) with longitudinal seams (18a-18n) forming longitudinal channels (20a-20n) for the insulation material (22) having individual insulation material (22) bundle in-side each longitudinal channel (20a-20n). Also disclosed are a method and an arrangement for producing the same.

A method of joining a metal and a plastic member, a method of joining a CFRP member and a plastic member, a method of joining a metal and a CFRP member through a plastic member, in particular a method of joining members able to join members by a faster joining speed and able to give a joined member excellent in joining strength are provided. A method of joining a metal and a plastic member by overlaying a metal and a plastic member and joining them by firing a laser beam from the plastic member side, comprising overlaying the plastic member and glass through which the laser beam will pass on the metal in that order and firing the laser beam from the plastic member side through the glass at a joining location where the metal and the plastic member are overlaid to join them by a joining speed of 0.5 m to 5.0 m/min.

A new ultrasonic aided laser joining method (UAL) for bonding dissimilar materials has been developed. The method is capable of eliminating the laser-induced bubbles at the bonding faces and to improve the joint strength over that of the conventional laser-assisted metal and plastic joining method (LAMP). Some experiments on joining titanium to polyethylene terephthalate have been conducted to show the superiority of UAL over LAMP. The results showed that the joint strength, measured in terms of failure load, was significantly increased when ultrasonic vibration was employed during laser joining. For the LAMP joined specimens, fracture normally occurred at the metal-plastic interface, whereas for the UAL joined specimens, fracture normally occurred in the parent plastic part. The improvement in joint strength is mainly due to the elimination of pores in the resolidified plastic. In addition, ultrasound vibration promotes chemical bonding between the plastic and metal parts, and this is supported by the XPS results.

A laser welding method and system for joining portions of first and second workpieces of thermoplastic material that is partially permeable to a laser beam but absorbs radiation from the laser beam. The first and second workpieces, which are made of material that absorbs radiation from a laser beam, are clamped together. A mask is placed on a first surface of the first workpiece, the first surface being opposite the surface engaging the second workpiece. The mask is impermeable to a laser beam and forms a slot for passing a laser beam to the portion of the first surface of the upper workpiece exposed by the slot, so that heating and melting of the material of the workpieces is limited to the width of the slot. A laser beam is directed onto the slot and moved in a manner to illuminate the slot to melt and join the workpieces.

A method for producing anchor rods from a fiber composite material includes a solidifying step during which a strand of a curable matrix material with embedded fibers is conveyed to an irradiation device and solidified by an irradiation with light. In a subsequent curing step, the solidified strand is conveyed to an annealing device and is cured by heating to an annealing temperature. A portion of the cured strand forms an anchor rod. The strand is continuously conveyed past or into the irradiation device in a depression of a circulating conveyor belt. The depression of the conveyor belt comprises profiled inner wall regions, via which, during the solidifying step, a surface profiling of the strand conveyed therein is effected. The conveyor belt consists of a light-permeable material, so that multiple illumination devices can illuminate the strand conveyed on the conveyor belt from various directions.

A method for welding a first hose end at a joint with a second hose end in a seam that extends on a circumference of the first hose end, the method comprising the steps: applying a protective layer at the joint to an inside of the first hose end; pushing the second hose end beyond the joint over the first hose end; pressing the first hose end and the second hose end together flat at the joint between two first damping jaws that are moved towards each other; welding the first hose end and the second hose end together by two first partial seams while pressed together, wherein the protective layer prevents a welding of the inside of the first hose end; releasing the first hose end and the second hose end from the two first clamping jaws after welding the two first partial seams.
