  • Patent number: 9242394
    Abstract: A method for heating a fiber/plastic composite material (FPC) comprising at least one layer (L) of carbon fibers (F) in a plastic matrix (P) includes inducing a magnetic field (MF) by means of a microwave antenna (MA) in the fiber/plastic composite material (FPC), and the field direction of the magnetic field (MF) runs in a plane of the layer (L) of carbon fibers (F).

  • Patent number: 8499429
    Abstract: In a method for applying a surface structure to a solid body, a structured surface is placed directly or indirectly onto the surface of the solid body and the structure of this structured surface is reproduced in the surface of the solid body, in that an explosive structured layer is arranged on the surface of the solid body and the structure of the explosive structured layer is explosively disseminated into the surface of the solid body. According to the invention, the surface of the solid body is provided with a surface pre-structure before the actual dissemination, at least in regions, wherein the structure of the explosive structured layer is disseminated on at least one partial region of the surface pre-structure so that the surface structure produced results from overlapping of the surface pre-structure with the explosively disseminated structure.

  • Publication number: 20110099784
    Abstract: A method for applying a surface structure to a solid body, wherein a structured surface is placed directly or indirectly onto the surface of the solid body and the structure of this structured surface is reproduced in the surface of the solid body, in that an explosive structured layer having the structured surface is arranged on the surface of the solid body and in that the structure of the explosive structured layer is disseminated by ignition of the same in the surface of the solid body; and/or at least one moulded structured layer having the structured surface is arranged on the surface of the solid body and is disseminated in the surface of the solid body by igniting a separate explosive layer, According to the invention the surface of the solid body is provided with a surface pre-structure before the actual dissemination, at least in regions, wherein the structure of the explosive structured layer or the moulded structured layer is disseminated on at least one partial region of the surface pre-struc

  • Patent number: 6591753
    Abstract: A propellant device of consisting of a compact charge and a firing system for pipe weapons or ballistic drives is proposed. At least one electromagnetic radiation absorbing medium, e.g. carbon black, is dispersed in the compact charge and can be activated by means of a firing system emitting electromagnetic radiation. The compact charge is thereby disintergrated in fragments through triggering of the firing system and the fragments are accelerated into the gas volume produced during burning of the compact charge. The inventive propellant device avoids the use of chemical firing as well as mechanical firing means. Moreover, fragmentation of the compact charge permits maintenance of the produced maximum pressure over a longer period of time to impart a higher muzzle velocity to an object to be accelerated, e.g. a projectile, a rocket or the like.
