Abstract
The trend towards lightweight construction leads to an increased use of lightweight materials such as aluminium alloys and fibre-reinforced plastics with a thermoplastic matrix. An adequate joining technology for these material combinations is ultrasonic welding. It is distinguished by a broad spectrum of weldable materials and material combinations. Besides joining parameters, the surfaces of the joining partners are crucial for the joint strength. Especially topography influences many physical and mechanical joining mechanisms. These effects can be intensified by a systematic microstructuring of the joining partners. Within this work, the ultrasonic welding of the aluminium alloy 5083 and thermoplastic carbon fibre-reinforced plastics (TPU) matrices was investigated. The study is based on a statistical experimental methodology that allows for a reduction of the experimental effort.
