FUNCTIONAL FILLERS FOR E-MOBILITY

Booth: Hall 5 - E56

The
requirements
for
many
electromobility applications have
not yet been defined and can vary
depending on the country, automobile
manufacturer or supplier. At the
heart of all developments, however,
are materials for the electrification
of automotive drive systems. The risk of fire due to technical
defects will increase as the number of electrical and electronic
components will increase drastically. Flame-retardant plastics
will have the highest priority. But the plastics of the future will
also have to offer properties such as high thermal conductivity and
chemical resistance. For mechanically highly stressed components, the
compounds or composites should have high toughness, stiffness and
strength. The special challenge for material developers and designers
will be to put together the perfect combination of materials with the
required properties. In particular, thermosets and thermoplastics will
increasingly replace steel, aluminium and cast iron. Higher mechanical
strengths of plastics are also required.
This is where HPF Minerals' high-performance fillers come in,
because their use can have a targeted effect on the properties of
polymer systems. The company's product range includes: Silatherm
for thermally-conductive plastics, Tremin for excellent dimensional
stability, Silbond for increased weather and chemical resistance, and
kaolin as flame retardant additives. www.hpfminerals.com

A NEW POLYESTER-BASED
COLOURANT LINES

Booth: Hall 5 - N21

At the 2020 JEC World Composites
show in Paris, Chromaflo Technologies
will present additional colourants for its
polyester-based Plasticolors GTS for
gelcoats and Plasticolors CF for versatile
polyester composite applications. The innovative Plasticolors
GTS is a fully-integrated tinting system for colouring polyester
gelcoats. For specific high-end applications, inorganic colourants
are added to the base selection, such as a cobalt blue and a
chrome oxide green-based colourant. For additional expansion
of the colour space, a violet colourant has been developed. The final
selection of 14 colourants in the GTS system provides gelcoat producers
with an innovative solution to meet the increasing colour demand in
the market without compromising performance. All GTS colourants
are low-viscosity, highly-concentrated solutions suitable for volumetric
and gravimetric use in automated dispensing machines. In addition,
Chromaflo expanded its Plasticolors CF line for versatile polyester
composite applications. Specialty colourants such as metallics and
fluorescent colourants were developed and added to the already broad
selection. The growing demand to expand the colour space and the
need to differentiate in colouring composites can be met with these new
developments. www.chromaflo.com

Structural adhesives
are widely used in
many
industries
such as automotive,
aerospace,
microelectronics, shipbuilding,
energy
and
sports & leisure. Strong efforts have been deployed to enhance
the level of adhesion in structural assemblies. In a context of
growing environmental concerns, the question now arises of
how to dismantle structural-bonded joints for end-of-life recycling.
Based on INDAR INSIDE technology (Innovative Disassembly
Adhesives Research), the solutions developed by Rescoll make it
possible to integrate environmental criteria in product design for
bonded assemblies. Available as adhesives and primers, they can be
thermally triggered on-demand to allow easy and clean disassembly,
thus facilitating the sorting and recycling of bonded assemblies, or
the recovery of parts for the second-hand market. INDAR INSIDE
technology may be implemented in different families of adhesives.
Apart from end-of-life scenarii, Rescoll's solutions are relevant for other
applications such as:
* Maintenance: replacement of worn parts, component upgrade;
* Temporary fixing: machining, release on command (e.g. in flightspace applications), proof tests, sensor bonding;
* Safety, e.g. panels with restricted access (instead of screwed panels).

DEVELOPMENT OF COMPOSITE
MATERIAL MODELS AS A SERVICE

An accurate material model is the key for reliable prediction
of composite mechanical behaviour through simulation, thus
allowing design optimization as part of the development process
and, finally, verification of the performance of the design without
extensive physical testing. Multiscale material modelling proved
to be a promising approach to accurately predict the behaviour of
fibre-reinforced composites all the way to rupture. The multiscale
material models developed with Altair Multiscale Designer can
be used in common finite element solvers. Special multiscale
knowledge is no longer needed to use the advanced material
models in simulation. For the material model development, Altair
has well-defined procedures
and test matrices for standard
composites, including unidirectionals, weaves, and
short-fibre
composites.
Nevertheless,
developing
the material model still requires a certain level of expertise and experience. Therefore, Altair is
now offering multiscale material model development as a service.
Starting with a review of the material characterization needs together
with the customer, the required tests are defined. The test laminates
produced by the customer with the in-house processing parameters
are then sent to a test laboratory of choice. Based on the test results, a
multiscale material model is developed by Altair experts and delivered
to the customer, ready for use in simulations. www.altair.com
