  • Color-based heating system
    Patent number: 10919186
    Abstract: A color based heating system is disclosed. A film for repair of aircraft components of fiber reinforced plastic has color changing properties that can include being temperature-dependent. The color changing properties can be reversible. A system for heating a repair site of a component of fiber reinforced plastic includes the film, a camera and a heating plate. The heating plate can have individually controllable heating zones. A controller can use local color signals of the camera for locally controlling local heating zones of the heating plate. The controller can assign local color signals of the camera to temperatures.

  • Repair concept comprising pre-impregnated pinned foam core for sandwich structural components
    Patent number: 10611102
    Abstract: A method for repairing a sandwich composite structure comprising a pinned foam core. In the sub-region in which the pinned foam core is damaged, the at least one upper or lower cover layer is removed as far as the pinned foam. The pinned foam core is removed. A pinned replacement foam core is inserted, the pinned replacement foam core being impregnated with a resin. An upper or lower replacement cover layer is applied. The pinned replacement foam core and optionally the upper or lower replacement cover layer are cured.
