BÜFA Composite Systems presents a new gelcoat
> Booth: Hall 5
The name of the latest product that has come from BÜFA Composites' research & development activities keeps its implied - E58/G23
promise: BÜFA®-Ambition-Gelcoat stands for the highest surface quality in a class with lacquers.
Gelcoats that until now were applied as a protective layer onto moulded parts made of fibre-reinforced plastics can now be replaced
by a new gelcoat: BÜFA®-Ambition-Gelcoat, which combines unique colour brilliance and accuracy with surface protection and refinement in
a class with lacquers. Whether orange, violet or azure blue - there are now no more
limits to individuality when it comes to applications in the automotive or industrial sectors.
An isophthalic acid resin and exceptionally colour-stable pigments are used as the basis for
this new gelcoat. The gelcoat also guarantees outstanding weathering properties because
products from BÜFA - Europe's leading gelcoat supplier - are produced with proven raw
materials and tested according to long-term methods.

Hybrid Twin by ESI
> Booth:
in Composite Factory 4.0
Hall 5 - N68
The Hybrid Twin innovation constitutes a new paradigm in simulation-based engineering sciences that ESI Group started to deploy
in the RTM (Resin Transfer Moulding) composite manufacturing
chain in partnership with Cannon. The Hybrid Twin replicates the
reality of the production line in a virtual world, allowing real-time control
and decision making. The technology is based on standard virtual prototyping, but in real-time and on a so-called data-driven corrective parameter introduced in the model.

Virtually predicting and
> Booth:
mitigating failure in composites
Hall 6 - R49
The MultiMechanics virtual testing software package drastically reduces the time and costs associated with testing and certifying new
materials. Before this technology, testing new material designs used
to take an average of $20M and three years. Even with the time and
money spent on
these tests, most
new design ideas failed to meet
requirements.
A d d i t i o na l l y,
simulation tools
were not meant
to be used by
material developers,
which
made virtual testing almost impossible. Materials certification was an
even longer and more expensive process, particularly in the aerospace industry. On average, certifying a new aerospace material required $100M
and ten years.
The software package empowers engineers with an unmatched level of
accuracy in simulations of advanced materials. Run times that require
24 hours with traditional tools only require 12 minutes with MultiMech
software. Traditional simulation tools require 54.5 GB of memory, while
it requires only 2.2 GB, enabling engineers to perform complex material
simulations on a laptop.
By reducing the time and costs associated with product development,
MultiMechanics empowers engineers to make safer, cleaner, and more
efficient products.

The real-time target is reached using a new model order reduction technique called PGD (Proper Generalized Decomposition) that results in
the construction of a numerical abacus providing an instantaneous response to any problem. Then, a data-driven corrective parameter fills the
gap between the physical models and reality.
With variations due to time or ignored or unexpected phenomena, discrepancies between reality and simulation may be observed, but the
Hybrid Twin's corrective parameter realigns the virtual world with reality.
This parameter comes from offline libraries containing masses of information from research as well as the numerical world.
This dual hybrid approach
(real-time physical models
combined with data-driven
correction) differentiates this
innovation from the digital
twin approach and allows a
very accurate representation
of reality, making real-time
control possible.

Modelling the thermo-mechanical behaviour of porous materials
> Booth:
EC2-Modélisation develops an original software program specifically designed to model the thermo-mechanical behaviour of
Hall 5 - E70
porous materials. This flexible numerical tool, named MODelia, can compute the whole set of thermal properties and investigate a very wide range
of porous materials with adjustable structural and composition parameters. It can also extract accurate finite elements meshing of the porous structure. MODelia is the result of the company's extensive research background in the field of heat transfer. The models and numerical methods used
were presented in several publications in peer-review international journals.
