Abstract
Ultrasonic welding is an environmentally friendly, nontoxic welding process preferred by top industrial manufacturers and in accord with the European circular economy regulation. Ultrasonic welding is an environmentally friendly, nontoxic welding process preferred by top industrial manufacturers and in accord with the European circular economy regulation. This scientific article analyses the ultrasonic welding behaviour of composites fabricated by additive manufacture technology using reinforcements, such as: glass fibre, Kevlar, Cu wire, etc. These materials are organized in a „sandwich” structure with different reinforcements and welded by ultrasound. Results were interpreted and compared with base material after performing NDT and destructive tests, namely: visual analysis, microscopic and macroscopic investigations: tensile tests, hardness tests, bending tests.
