Abstract
A repair method is provided during which an ultrasonic horn is arranged on a thermoplastic component. The thermoplastic component extends vertically between a first surface and a second surface. The thermoplastic component includes a delamination disposed vertically between the first surface of the thermoplastic component and the second surface of the thermoplastic component. The ultrasonic horn horizontally overlaps the delamination. The thermoplastic component is horizontal ultrasonic welded using the ultrasonic horn to repair the delamination.
Claims20
A repair method, comprising:
- arranging an ultrasonic horn on a thermoplastic component, the thermoplastic component extending vertically between a first surface and a second surface, the thermoplastic component comprising a delamination disposed vertically between the first surface of the thermoplastic component and the second surface of the thermoplastic component, and the ultrasonic horn horizontally overlapping the delamination;
- and
- horizontal ultrasonic welding the thermoplastic component using the ultrasonic horn to repair the delamination.
A repair method, comprising:
- arranging an ultrasonic horn on a thermoplastic component, the thermoplastic component extending vertically between a first surface and a second surface, the thermoplastic component including a first layer, a second layer and a damaged region where the first layer separates from the second layer at a location vertically between the first surface of the thermoplastic component and the second surface of the thermoplastic component, and the ultrasonic horn horizontally overlapping the damaged region;
- and
- ultrasonic welding the thermoplastic component using the ultrasonic horn to bond the first layer to the second layer within the damaged region, the ultrasonic horn vertically engaging the second surface of the thermoplastic component, and the ultrasonic horn moving horizontally back-and-forth along the second surface of the thermoplastic component during the ultrasonic welding of the thermoplastic component.
A repair method, comprising:
- arranging an ultrasonic horn on a thermoplastic component, the thermoplastic component extending vertically between a first surface and a second surface, the thermoplastic component including a first layer, a second layer and a damaged region where the first layer is unbonded from the second layer at a location vertically between the first surface of the thermoplastic component and the second surface of the thermoplastic component, and the ultrasonic horn horizontally overlapping the damaged region;
- and
- ultrasonic welding the thermoplastic component using the ultrasonic horn to bond the first layer to the second layer within the damaged region, the ultrasonic horn vertically engaging the second surface of the thermoplastic component, and the ultrasonic horn moving horizontally back-and-forth along the second surface of the thermoplastic component during the ultrasonic welding of the thermoplastic component.
