Joining techniques
Among the welding/thermal
joining techniques researched
so far, metal-polymer ultrasound welding seems to be
the most promising one for
hybrid structures. This method
has been successfully used to
join metal and glass fibre-reinforced polymers. Friction-stir
welding provides similar
results to ultrasound welding.
However, a limitation of this
technique is that it is mainly
recommended for materials
with a low melting point and
it is not applicable to very

proach for challenges, emerging technologies and new opportunities in the field
of dissimilar materials joining.
This workshop highlighted alternative
joining solutions for plastics, composites
and advanced materials based on more
efficient and economic production technologies that make it possible to produce
light structures, and therefore reduce
energy consumption and environmental
impacts. n
