Abstract
A molding device for curing of composite components comprising: a molding die, composite material in the molding die, heat application means, sheathing means for the composite material and the molding die and vacuum means for the application of vacuum to the composite material in the molding die. The heat application means comprise at least one heat pipe with a heat exchanger attached to the molding die for thermal conduction to the composite material.
Claims20
A molding device for curing of composite components comprising:
- a molding die;
- heat application means;
- sheathing means for sealing the composite components and the molding die off about at least one vacuum chamber;
- and
- vacuum means applying a vacuum to the composite components in/on the molding die via the vacuum chamber, wherein
- the heat application means comprise at least one heat pipe integrated into the molding die for heat exchange to the molding die for thermal conduction to the composite components.
A molding device for curing of composite components comprising:
- a molding die supported by a base plate and defining a vacuum chamber therein;
- a sheathing foil configured to seal composite components and the molding die off about the vacuum chamber;
- a vacuum source configured to apply a vacuum to the composite components on the molding die via the vacuum chamber;
- and
- a heat pipe integrated into the molding die for heat exchange to the molding die for thermal conduction to heat the composite components, the heat pipe comprising a closed tube containing a working fluid, the closed tube having a first end in contact for heat exchange with the molding die and a second end spaced apart therefrom, wherein the heat pipe is configured such that the working fluid is locally heated and evaporated at the second end and the working fluid is condensed at the first end to supply heat to the molding die.
A molding device for curing of composite components comprising:
- a molding die supported by a base plate and defining a vacuum chamber therein;
- a sheathing foil configured to seat composite components and the molding die off about the vacuum chamber;
- a vacuum source configured to apply a vacuum to the composite components on the molding die via the vacuum chamber;
- an inner heat pipe integrated into the molding die for heat exchange to the molding die for thermal conduction to heat the composite components, the inner heat pipe positioned within the vacuum chamber, the inner heat pipe having a first end region in contact for heat exchange with the molding die and a second end region in contact for heat exchange with the base plate;
- and
- an outer heat pipe having a first end region in contact for heat exchange with the base plate and a second end region provided with fins.
