  • Patent number: 9878502
    Abstract: In a method for processing a fiber compound structure, an unhardened fiber layer is arranged on a surface section of the fiber compound structure. A pressure cushion is arranged above the surface section. The pressure cushion has a pressure cap and a pressure-tight cap mat pressure-tightly connected to a circumferential border of the pressure cap such that the cap mat limits a pressure area together with the pressure cap. An overpressure in the pressure area is generated. The pressure cushion is pressed onto the fiber compound structure such that the overpressure presses the cap mat against the fiber layer while supporting the fiber compound structure on a side of the fiber compound structure that is opposed to the surface section.

  • Patent number: 9463599
    Abstract: The present invention provides a connecting device for connecting an unhardened fiber layer which is arranged on a surface section of a fiber compound structure to the fiber compound structure. The connecting device comprises pressure cushion comprising a pressure cap for being arranged above the surface section and a pressure tight cap mat which is pressure tightly connected to a circumferential border of the pressure cap, thereby forming a pressure area which is limited by the pressure cap and by the cap mat. The connecting device further comprises a pressure inducing means for inducing an overpressure which presses the cap mat against the fiber layer into the pressure area. According to a further aspect the invention provides a processing method for processing a fiber compound structure. In a first step at least one unhardened fiber layer is arranged on a surface section of the fiber compound structure.

  • Patent number: 8109469
    Abstract: A module for an aircraft for accessing an upper region of the aircraft includes both an ascent region and an accommodation region, with the regions being divided from each other by a divider element. The accommodation region may, for example, be designed as an on-board lavatory. In this way it may be possible to do without the provision of an additional lavatory monument.
