Abstract
A repair method is provided during which a thermoplastic patch is arranged on a thermoplastic aerospace component. The thermoplastic patch contacts the thermoplastic aerospace component. The thermoplastic patch is horizontal ultrasonic welded to the thermoplastic aerospace component using an ultrasonic horn.
Claims17
A repair method, comprising:
- arranging a thermoplastic patch on a thermoplastic aerospace component, the thermoplastic patch contacting the thermoplastic aerospace component, the thermoplastic aerospace component including an aperture, an exterior surface and an interior surface, the aperture extending into the thermoplastic aerospace component from the exterior surface to the interior surface, and the thermoplastic patch disposed in the aperture and contacting the interior surface;
- horizontal ultrasonic welding the thermoplastic patch to the thermoplastic aerospace component using an ultrasonic horn;
- arranging a second thermoplastic patch in the aperture, the second thermoplastic patch contacting a surface of the thermoplastic patch;
- and
- horizontal ultrasonic welding the second thermoplastic patch to the thermoplastic patch using the ultrasonic horn.
2 more elements
A method, comprising:
- removing material from a first thermoplastic body to form an aperture in the first thermoplastic body, the aperture extending into the first thermoplastic body from an exterior surface of the first thermoplastic body to an interior surface of the first thermoplastic body;
- arranging a second thermoplastic body in the aperture, the second thermoplastic body contacting the interior surface of the first thermoplastic body;
- ultrasonic welding the second thermoplastic body to the first thermoplastic body using an ultrasonic horn, the ultrasonic horn engaging a surface of the second thermoplastic body, and the ultrasonic horn moving back-and-forth along the surface of the second thermoplastic body during the ultrasonic welding of the second thermoplastic body;
- arranging a third thermoplastic body in the aperture, the third thermoplastic body contacting the surface of the second thermoplastic body;
- and
- ultrasonic welding the third thermoplastic body to the second thermoplastic body using the ultrasonic horn, the ultrasonic horn engaging a surface of the third thermoplastic body, and the ultrasonic horn moving back-and-forth along the surface of the third thermoplastic body during the ultrasonic welding of the third thermoplastic body.
3 more elements
A method, comprising:
- providing a first thermoplastic body with a damaged portion;
- arranging a second thermoplastic body on an exterior surface of the first thermoplastic body, the second thermoplastic body covering a damaged portion of the first thermoplastic body;
- and
- ultrasonic welding the second thermoplastic body to the first thermoplastic body using an ultrasonic horn, the ultrasonic horn engaging a surface of the second thermoplastic body, and the ultrasonic horn moving back-and-forth along the surface of the second thermoplastic body during the ultrasonic welding of the second thermoplastic body.
