  • Publication number: 20140374012
    Abstract: A device and method for manufacturing a bonded component with fiber-reinforced plastics with a base molding tool and a molding tool. The adhesive component is arranged between the base molding tool and the molding tool. The bonded component has a base laminate and a reinforcement laminate. The molding tool is covered with an aeration material and a vacuum envelope. The vacuum envelope is sealed with respect to the base molding tool. The molding tool is at least partially formed from a metal alloy, which has an anomalous thermal expansion coefficient. Undesirable lost cavities in the device are reduced to minimize reductions in thickness in the end face or longitudinal face regions of the cured bonded component. A seal can additionally be provided, as can at least one molding tool free of projections, and also an aeration material arranged on the at least one molding tool in only some regions.

  • Publication number: 20140300021
    Abstract: A device and method for the manufacture of a bonded component from fiber-reinforced plastics, with a base molding tool and a molding tool. The bonded component is arranged between the base molding tool and the molding tool. The bonded component has at least one base laminate and at least one reinforcement laminate. The molding tool is covered with an aeration material and with a vacuum envelope. The vacuum envelope is sealed with respect to the base molding tool by means of a seal. At least one matrix material film is arranged underneath at least one molding tool overhang, in at least some regions. Undesirable cavities within the device are primarily filled with material from the matrix material film, so that leakage flows of matrix material from the bonded component reduce during the autoclave process. By this means complex and cost-intensive rework of the bonded component is avoided.

  • Publication number: 20140290840
    Abstract: A device and a method for the manufacture of a bonded component from fiber-reinforced plastics, with at least one base molding tool and at least one molding tool. The bonded component is arranged between the base molding tool and the molding tool. The molding tool is covered with an aeration material and with a vacuum envelope. The vacuum envelope is sealed with respect to the base molding tool by means of a seal. At least one end face of the bonded component, in at least some sections, ends flush with at least one end section of at least one molding tool, or projects underneath the latter. The molding tools have essentially the same build height and also raked end sections. In each case molding tools adjoining one another are preferably provided with a vertical interlock. By this means the number of undesirable cavities in the device is reduced.

  • Publication number: 20140158282
    Abstract: A device and method with at least one base molding tool, at least one release layer and an aeration material, for the manufacture of a bonded component from fiber-reinforced plastic, wherein the bonded component, the aeration material and the release layer are covered with a vacuum envelope sealed with respect to the base molding tool. The aeration material is attached to the base molding tool by at least one fixing element, in particular a Velcro-type tape with hooks or mushroom heads, wherein the fixing element can be repeatably released and attached, and can be used on multiple occasions. The tape with hooks or mushroom heads operating on one or both sides allows for the rapid fixing of location of the aeration material that is necessary within the device. After the completion of the curing process in the autoclave, the aeration material can be released rapidly from the base molding tool.

  • Publication number: 20140150969
    Abstract: A device and method for manufacturing a bonded component with fiber-reinforced plastics having at least one base molding tool and at least one molding tool. The bonded component is arranged between the base molding tool and the molding tool. The bonded component has a base laminate and a reinforcement laminate. The molding tool is covered with an aeration material and a vacuum envelope. The vacuum envelope is sealed with respect to the base molding tool. At least one filler element is fitted to each of the two end faces of the base laminate in a gap-free manner. With the filler elements, as well as optionally provided sealing elements, undesirable cavities within the device, as a result of thermal expansion effects of the upper molding tool, as well as any deviations of location and/or size of the base laminate, the reinforcement laminate, and also the molding tool, are significantly reduced.

  • Patent number: 8192674
    Abstract: The invention concerns an apparatus and a process for the production of a structure from fiber composite material, comprising a mold tool for receiving material which can be joined to provide a structure, and a vacuum system for molding and fixing the structure, wherein the vacuum system has a flexible layer, in particular a separation film or separation layer and/or a tear-off film, and a vacuum film for covering the structure. In accordance with the invention the vacuum system is free from ventilation material and/or tear-off material at least at a portion which corresponds to a portion of the structure to be covered, in which a step extends.
