Patent number: 5505007Abstract: Fiber reinforced structural components, such as panels with honeycomb cores sandwiched between at least two outer skin layers are dried to remove moisture that may have entered into the interior of the structure. For this purpose the component is cooled in a cooling environment below the freezing point to about -5.degree. to -20.degree. C. and then exposed to a reduced pressure of less than 0.5 mbar. Under these drying conditions moisture is driven out of the component by sublimation so that the moisture does not pass through the liquid phase. The drying time may be reduced by a temperature increase to 80.degree.-100.degree. C. while maintaining the low pressure. The freezing increases the capillary action for the moisture removal. However, for an increased efficiency in the moisture removal small diameter holes, e.g. 0.1 mm bores, may be drilled into the component to facilitate the moisture escape. After drying is complete the holes are closed again e.g. by laminating further cover sheets to the component.Type: GrantFiled: December 15, 1994Date of Patent: April 9, 1996Assignee: Daimler-Benz Aerospace Airbus GmbHInventor: Bernd Raeckers
