Abstract: To reduce the processing time in the case of repairing of excessively countersunk bolt openings or surface damage in fiber composite workpieces, it is proposed to countersink the corresponding surface spot to produce a contact surface and a depression for a fiber composite insert body. The fiber composite insert body is placed onto the contact surface and is fixed on the fiber composite workpiece in the depression. In the case of an excessively countersunk bolt opening, a new bolt opening is drilled into the fiber composite insert body, which new bolt opening is subsequently countersunk to the correct countersunk bore depth. In the case of the method, a three-legged application tool can be used which positions and orients the fiber composite insert body correctly and presses it onto the fiber composite workpiece during the curing of the adhesive.

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.
