Abstract
A method is provided for joining a fiber-reinforced joining element, formed from a plastic material, to the joining surfaces thereof by way of an ultrasonic welding method. A concentrator and/or at least one insertion element is arranged in the region of the joining surfaces prior to fusing between the joining surfaces, and the concentrator and/or the insertion element are fused together with the joining surfaces in order to form a positive fit joint therewith after hardening.
Claims8
A method for joining fiber-reinforced joining partners formed of a plastics material, the method comprising the acts of:
- applying a concentrator in a region between connection faces of the joining partners;
- and
- fusing together, via ultrasonic welding, the connection faces such that a materially integral joint is obtained post-curing as a mixing region configured from materials of the joining partners and the concentrator;
- wherein the joining partners are composed of a thermoplastics material into which a plurality of endless fibers are embedded;
- wherein the concentrator comprises a fiber-reinforced plastics material;
- wherein post-curing, the materially integral joint comprises in each case one upper and lower boundary surface, wherein a plurality of reinforcement fibers of the concentrator protrude through the boundary surfaces and into adjacent material regions of the joining partners and contribute toward a strength of the materially integral joint.
A method for joining fiber-reinforced joining partners formed of a plastics material, the method comprising the acts of:
- applying an insert in a region between connection faces of the joining partners;
- and
- fusing, via ultrasonic welding, the connection faces such that the insert is embedded in a materially-integral manner into the connection faces and a form-fitting joint is obtained;
- wherein the joining partners are composed of a thermoplastics material into which a plurality of endless fibers are embedded;
- wherein the insert comprises a fiber-reinforced plastics material;
- wherein post-curing, the form-fitting joint comprises in each case one upper and lower boundary surface, wherein a plurality of reinforcement fibers of the insert protrude through the boundary surfaces and into adjacent material regions of the joining partners and contribute toward a strength of the form-fitting joint.
