lndustrial laser processing of fibre-reinforced plastics
The technology was developed within the EU's PMJoin project, together
with partners from the automotive industry. A demonstrator in the form of
a car door with a GFRP reinforcing
brace was produced. The partners in
the FlexHyJoin follow-up project are
currently working on a fully-automated
version of the process.
Metal inserts in textile preforms
Screws and rivet fittings are the traditional force transmission elements
for metal components. However, the
integration of such functional elements
becomes far more complicated in the
case of fibre-reinforced plastics. In
particular, the placement of drill holes
to create form-locked or friction-locked
connections requires a high level of
expertise.
As part of the LaserInsert project funded by the German Federal Ministry
of Economic Affairs (BMWi), the

ensure a positive
locking connection

Fraunhofer ILT team is currently working on a mass production-ready laser-based process to address this issue.
First, an ultrafast laser is utilized to ablate holes in the textile preform before it
is impregnated with resin. Then, a metal
insert is placed and the resin matrix is
applied. The final result is a consolidated
work piece featuring a metal-FRP hybrid
structure.
In addition to optimizing processes, the
project partners are also working to
enhance the textile structures, which,
in combination with laser processing,
offer improved locking and friction
joining properties with the insert fasteners. The targeted users of this technique are the automotive and aviation
industries.
