EPOXY TECHNOLOGY FOR HIGHVOLUME LEAF SPRING PRODUCTION

Multi-sector

Booth: Hall 6 - G52

Composite leaf springs have been used in the automotive
industry for a long time, for example in the GM Corvette,
Daimler Sprinter and Volvo models from the new Scalable
Product Architecture (SPA) platform. Significant weight
savings of 65-80% can be achieved compared with steel
equivalents, making composite leaf springs attractive
solutions to comply with tightening environmental regulations.
In addition, the weight reduction is realized in the unsprung
mass, leading to better driving behaviour. Although different
manufacturing methods can be used to mould composite
leaf springs, high-pressure-RTM (HP-RTM) is most cost efficient at
high build rates. The RTM technology has a proven robustness in
commercial applications and is suitable due to the availability of fastcure resin systems and compatible internal mould release agents and
preform binders. The EPIKOTE Resin TRAC 06150/EPIKURE Curing
Agent TRAC 06150/HELOXY Additive TRAC 06805 allow for fast
conversion out of the mould, eliminating the need for post-cure. In a
typical production setting with a multi-cavity tool, this translates into
per-part cure times well below one minute. Binder-stabilized fabrics
are easier to handle and position in the mould, which is particularly
important when large ply stacks need to be handled like in the
manufacturing of leaf springs. The reactive binder EPIKOTE Resin
TRAC 06720-3 offers excellent ply adhesion and is fully compatible
with the fast-cure epoxy system. www.hexion.com

Multi-sector

COBRA International, the market leader in serial production of strong, light and beautiful composite products, has been pioneering the introduction
of more sustainable composite raw materials for more than a decade. With bio-based epoxy systems, natural fibre reinforcements and recycled
content in foam core materials, COBRA has already made great progress. Working with partners Aditya Birla and Starboard, the company is
now taking an even bigger leap forwards in sustainable development by incorporating the first recyclable epoxy thermoset systems into their
production. By using Aditya Birla's Epotec YDL5552-THR935 recyclable epoxy systems to infuse windsurf fin moulds and the Epotec YDL5540THR9151 recyclable epoxy RTM system to produce components, COBRA and their partners have initiated a closed-loop recycling process
that will significantly reduce composite material waste volumes. The company CNC machines their tooling from infused fibreglass mould blocks
before laying up carbon and fibreglass fabric preforms for RTM injection. Aditya Birla's unique resin technology can be easily broken down
using a low-temperature recycling process, leaving a thermoplastic resin compound and the reinforcement fabrics recovered intact. This exciting
development has massive potential for the thermoset composite markets as a whole and COBRA will be showing more details of their work, as
well as fins, moulds and plastic components moulded from the recycled thermoplastic, at JEC World 2020. www.cobrainter.com

WHITE CONDUCTIVE FLUOROPOLYMER
COMPOUNDS - FLOMELT

In the field of fluoropolymer conductive
compounds, one of the currently available
solutions includes the addition of conductive carbon (or carbonaceous fillers) to
polymer bases to make them conductive.
The drawback is that the conductive carbon used as a filler turns the final product black in colour and, as such,
is not accepted by the market, even considering the regulations limiting
the amount of carbon allowed within compounds coming into direct
contact with food. There is a strong need for fluoropolymer compounds
with the chemical and thermal resistance required by the pharmaceutical/
food fields, without the drawbacks associated with the use of fluoropolymer
compounds comprising conductive carbon.
Thanks to new developments, a category of white fillers has been identified
that provides a new family of fluoropolymer compounds that can grant surface
and volume resistivity values within 10E3-10E6 according to ASTM D4496-13.
Fluoropolymer compounds are widely used as internal linings for pipes, fittings,
valve bodies, pumps and containers in contact with fluids and powders where
there is an accumulation of electrostatic charges.
Such linings are required to meet specific field needs such as chemical
resistance, thermal resistance and low porosity, as well as anti-static
performance, preserving the safety, long life and FDA requirements of the
products. The white and conductive fluoropolymer compounds also fulfil the
ATEX regulation requirements. www.formulance.com

LOW-CTE THERMOPLASTIC RESIN FOR LARGE-SCALE 3D PRINTING

Booth: Hall 5 - E32

Airtech's new "Tooling of Tomorrow" initiative leverages the company's 45 years of polymer extrusion and
manufacturing expertise to address the needs of the large-scale thermoplastic composite 3D-printed tooling
industry. Additional facilities, equipment, and staff with over 15 years of large-scale additive experience
have been added to the global team to support this effort. The high-throughput and relatively low-cost
FDM (Fused Deposition Modelling) manufacturing method is used to create large tooling structures and
surfaces for low- to high-temperature lay-up moulds, trim or assembly fixtures, or masters. The structures
and materials used for these demanding tooling applications have to be durable and dimensionally stable.
Airtech developed a new series of innovative polymer composite resins, Dahltram, for use in large-scale 3D
printing that has addressed the need for lower CTE and a more robust service life when used at low or high
temperatures, including use in an autoclave. These thermoplastic composite resins are designed for use in any pellet-fed FDM printing system.
The company is utilizing its facilities in Springfield, TN (USA), and Differdange, Luxembourg, to house a pair of the largest commercially-available
3D printers (3x12m) in order to offer its Print-tech full-service tooling manufacturing solutions exclusively with Dahltram resins, as well as support
for continued research and development of future resin offerings for global customers. www.airtechonline.com
