  • Patent number: 7931458
    Abstract: Injection structure with a fiber-composite semifinished product for manufacturing a fiber-composite component, having a gate device for feeding matrix material, a distribution fabric, and a barrier layer that is impermeable to the matrix material, wherein the distribution fabric is arranged between the gate device and the fiber-composite semifinished product, and the barrier layer is arranged between the distribution fabric and the fiber-composite semifinished product, as well as device for manufacturing a fiber-composite component by this injection structure.
    Type: Grant
    Filed: July 30, 2004
    Date of Patent: April 26, 2011
    Assignee: EADS Deutschland GmbH
    Inventors: Thomas Lippert, Hans-Wolfgang Schroder, Franz Stadler, Stefan Utecht
  • Patent number: 7488371
    Abstract: Degassing device for degassing matrix material in the manufacture of fiber-composite components with a support device, a distribution fabric, a gate device, a discharge device, a matrix-material-impermeable barrier layer, which is sealed with respect to the support device by a seal and thus forms a first chamber of the degassing device located around the gate device, as well as a degassing device for degassing matrix material in the manufacture of fiber-composite components with a first connection, for conducting the matrix material to be degassed into the degassing device, a second connection for conducting the degassed fluid out of the same, and a third connection for applying negative pressure to the interior of the same, an inner body, a resin-impermeable and air-permeable film, and an outer housing.
