Abstract
A method for connecting two components. In this method, a first component and a second component, which are each formed from a thermoplastic material, are first provided. The first component has a first peel-off ply on a first surface of the first component. The first peel-off ply is removed from the first component. Once the first peel-off ply has been removed, the first surface of the first component is brought into contact with a second surface of the second component. The first component and the second component are then welded to one another at the first and second surface by ultrasonic welding.
Claims14
A method for joining two components, comprising:
- providing a first component and a second component, which are each formed of a thermoplastic polymer material, the first component having a first peel ply on a first surface of the first component;
- removing the first peel ply from the first component to form a surface profile in the first surface which comprises an arrangement of a multiplicity of elevations and depressions;
- after removing the first peel ply, contacting the first surface of the first component with a second surface of the second component;
- and
- subsequently welding the first component and the second component to one another on the first and second surfaces by ultrasonic welding;
- wherein the multiplicity of elevations and depressions are configured to steer ultrasonic energy produced by the ultrasonic welding into a contact region between the first surface and the second surface.
A method for joining two components, comprising:
- providing a first component and a second component, which are each formed of a thermoplastic polymer material, wherein providing the first component comprises producing the first component with a first peel ply on a first surface of the first component;
- removing the first peel ply from the first component;
- after removing the first peel ply, contacting the first surface of the first component with a second surface of the second component;
- and
- subsequently welding the first component and the second component to one another on the first and second surfaces by ultrasonic welding;
- wherein the peel ply is formed of a multiplicity of filaments and wherein producing the first component with the peel ply comprises selecting at least one value for at least one parameter from the group consisting of filament spacing, filament diameter, filament shape and mesh size, and selecting or producing as the peel ply a peel ply which has the selected parameter value.
