A pressure tool for rotor blade repair including a mobile support system including a support surface, a first bladder support assembly including a first inflatable bladder fixedly mounted to the support surface, a second bladder support assembly including a second inflatable bladder pivotally mounted relative to the support surface, and an activation mechanism operatively coupled to the second bladder support assembly. The activation mechanism is operable to selectively shift the second bladder support assembly relative to the first bladder support assembly. A fluid delivery system is operable to direct a fluid into each of the first inflatable bladder and the second inflatable bladder.

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.

A method for reconditioning a rollable wheel includes coupling a polymeric wheel to a reconditioning system, the polymeric wheel having an outer surface including an abraded area, the abraded area having a first average surface roughness, and applying heat to the abraded area of the outer surface with one or more heater of the reconditioning system, such that a substantial portion of the abraded area is transformed to have a second average surface roughness, the second average surface roughness less than the first average surface roughness.

A method for repairing a composite structure, includes creating a repair cavity in a composite structure, placing foamable media in the repair cavity, placing a replacement skin over the repair cavity, and expanding the foamable media placed in the repair cavity.

A method refurbishes structured surfaces of a component having a damaged subregion with material detachment. The method comprising: determining a reference region having a similar surface structure as the subregion; while pressing a die material onto the reference region: curing the die material to form a transparent die which is separable from the reference region without leaving residues and has a negative shape of the surface structure of the reference region; filling the damage location with electromagnetic irradiation curable material; placing the die onto the curable material in the damage location with an alignment of the negative shape of the transparent die corresponding to a desired surface structure at the damage location; while the die is being pressed onto the damage location: irradiating the curable material with electromagnetic irradiation through the transparent die until the material is cured; and removing the die from the cured material without leaving residues.
