The invention relates to a cover structure the SMC main body of which is simultaneously pressed and bonded with two additional layers in a bonding press.

A gas barrier film comprises a first base material film made of a plastic material and a coating layer formed on one of surfaces of the first base material film, the coating layer contains a water-soluble polymer and a water-swelling mica, the solid content ratios of the water-swelling mica in a total solid content of the coating layer are within approximate ranges indicated from 20 mass % to 50 mass %, the mean area diameter of the water-swelling mica is within approximate ranges indicated from 0.5 m to 5 m, and the thickness of the coating layer is within approximate ranges indicated from 0.1 m to 1 m.

Various embodiments may include a solid insulation material, e.g. in tape form, the use thereof in a vacuum impregnation process, and/or an insulation system produced therewith and also an electrical machine having the insulation system, for the medium- and high-voltage sector. Some examples include rotating electrical machines in the medium- and high-voltage sector and also semifinished products for electrical switchgear. The solid insulation material and the insulation system produced therewith are characterized in that it can be produced in an anhydride-free manner, wherein the curing catalyst is, for example, an adduct of a 1H-imidazole and/or 1H-imidazole derivative with a compound containing oxirane groups.

A highly reliable flexible light-emitting device is provided. The light-emitting device includes a first flexible substrate, a second flexible substrate, a light-emitting element between the first flexible substrate and the second flexible substrate, a first bonding layer; and a second bonding layer in a frame shape surrounding the first bonding layer. The first bonding layer and the second bonding layer are between the second flexible substrate and the light-emitting element. The light-emitting element includes layer containing a light-emitting organic compound between the pair of electrodes. The second bonding layer has a higher gas barrier property than the first bonding layer.

The present disclosure relates to insulation. Teachings thereof may be embodied in a solid insulation material, especially in tape form, the use thereof in a vacuum impregnation process and to an insulation system produced therewith, and also an electrical machine comprising the insulation system, especially for the medium- and high-voltage sector, namely for medium- and high-voltage machines, especially rotating electrical machines in the medium- and high-voltage sector, and to semifinished products for electrical switchgear. For example a solid insulation material with an anhydride-free impregnating agent may include: a carrier; a barrier material; a curing catalyst; and a tape adhesive. The curing catalyst and the tape adhesive are inert toward one another but react under the conditions of a vacuum impregnation process if combined with an anhydride-free impregnating agent having gelation times of 1 h to 15 h at impregnation temperature. The tape adhesive is free of oxirane groups and includes at least two free hydroxyl groups.

The present invention relates to a multilayer material comprising a layer of stone (1) laminated to a layer of reinforcing element (2) and its manufacturing process.

A flexible multilayer battery pack insulator for an electric vehicle having a multilayer wall including a plurality of layers. The plurality of layers includes an inner layer of mineral material having an inner surface and an outer surface, and an outer layer of mineral material having an inner surface and an outer surface. A flame-resistant coating, including silicone and mica, bonded to at least one of the plurality of layers. An adhesive layer bonded to the outer surface of the inner layer, and at least one filament fixing the plurality of layers to one another.

A laminate having thermal-protection and flame-retardant properties is disclosed. The laminate can include a flame-retardant layer and an aerogel layer, wherein the laminate has opposing front and back surfaces, the flame-retardant layer defines at least a majority of the front surface, and a thickness of the laminate is less than or equal to 25.4 millimeters (mm).
