    摘要: In order to manufacture compound composite bodies having at least two lay with a support material made completely or substantially from a polymer and with a porous layer firmly connected thereto, a substantially microwave-permeable polymer is utilized for the support material and a polymer having microwave absorbing properties is utilized for the porous layer. The polymer for the porous layer, treated with foaming agent, is heated with microwave energy up to the decomposition temperature of the foaming agent. The resulting polymer foam is sufficiently heated using microwave energy that the support material, at its bordering layer adjacent the foamed polymer, is sufficiently melted substantially due to heat conduction out of the foamed layer that, subsequent to cooling, a firm composite between the support material and the foamed polymer is effected. The porous layer can also consist essentially of polymer particles which melt together during the MW-irradiation and which are either pre-expanded or expanded during MW-irradiation through foaming agent additive.

    摘要: 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.

    摘要: The aim of the invention is to provide an alternative to the intensive treatment of a product, especially plasma treatment, in specific areas only. Towards this end, the invention provides a device for producing microwaves for treating workpieces, comprising at least one microwave antenna with an extended conductor for producing alternating electromagnetic fields, a housing that substantially extends over the length of the conductor, and an extended microwave decoupling area which follows the conductor and which is located in the housing. The housing is formed by at least one resonant cavity, which has a long shape and follows the course of the microwave antenna. The resonant cavity has at least one tapering, closed, first crown area and the decoupling area essentially extends in the focussing area of the resonant cavity. An at least non-divergent housing area adjoins the resonant cavity.

    摘要: A process for the production of hollow carbon fibres by the treatment of a stabilised carbon fibre precursor in an application device using high-frequency electromagnetic waves. The application device includes structure supplying the electromagnetic waves to a outcoupling region and a hollow outer conductor terminating in the outcoupling region. For the treatment, a field of the high-frequency electromagnetic waves is generated and a field strength in the range from 15 to 40 kV/m is set in the outcoupling region of the application device. The stabilised carbon fibre precursor is conveyed continuously as an inner conductor through the hollow outer conductor, thereby forming a coaxial conductor having an outer and an inner conductor, and through the subsequent outcoupling region. An inert gas atmosphere is created in the coaxial conductor and in the outcoupling region by passing through an inert gas.
