now focusing on 3D printing of a plastic yarn reinforced with carbon/epoxy
composite.

A350 model presented at JEC World 2017

The two-year project is financed by
the European Regional Development
Fund (FEDER) and led by Rescoll
in partnership with Stelia Aerospace,
C3Technologies, and the Marcel
Dassault secondary technical school
for plastics processing in Rochefort.
Through this project, the technological,
techno-economic and environmental issues involved are explored.
That is the framework around the project. On the technical side, one of the

Training Director
Lycée Marcel Dassault

What motivated the school's decision
to participate in this R&D project, and
how is that participation benefiting the
instruction given to your students?

Laurent Bouscaud: By virtue
of all its general technological and
professional training courses, the
Marcel Dassault Lycée, a comprehensive

upgrade challenges concerns the mechanical grinding of the carbon/epoxy
composite waste, which is a key step in
breaking the waste down to a size where
it can be integrated into a thermoplastic
resin as reinforcement. Rescoll currently uses this new compound (its excellent mechanical properties will be presented later on) to manufacture a yarn
dedicated to additive manufacturing.
After months spent perfecting this unusual blend and optimizing the different
methods for processing it, Rescoll is
secondary school in Rochefort sur Mer,
France, is concerned by sustainable
development, and more particularly by
material value development.
Through its professional training
courses in plastics processing,
composites and aeronautics, the school
has always maintained special ties
with the Rescoll laboratory and Stelia
Aerospace.
The synergy around the WasteCost
project in which the school participated
enabled it to pass a milestone in the
recycling of carbon/epoxy composites.
As part of their end-of-studies
project, a group of four students in
the "Europlastics and Composites"
Advanced Technician's Certificate

Additive manufacturing
The first conclusive tests took place in
Rescoll's plastics processing laboratory, but to test the reinforced yarn on
oversized parts, it was necessary to call
on other experts in France's NouvelleAquitaine region. For this new phase,
the IMA resource centre for aviation
maintenance engineering in Mérignac
and VLM Robotics in Mios joined
Rescoll.
Early this year, the WASTEcost project
team launched production of an Airbus
A350 mock-up using the reinforced
yarn - in a way, closing the loop, since
the waste itself comes from the Airbus
A350 manufacturing process within the
STELIA Aerospace group (see photo of
the vertical stabilizer).
programme were able to work
on the injection moulding and
characterization of a recycled carbon/
epoxy-reinforced thermoplastic-matrix
material. One of the school's teachers
mentored the project in conjunction
with the Rescoll laboratory and
Stelia, making it possible for them to
contribute to the feasibility stage.
In a follow-up to that collaborative
project, a head of project from the
Rescoll laboratory will lead a materialrecycling-themed activity for the
students in the STI2D (industrial
science and technology and sustainable
development) baccalaureate programme.
