INNOVATION REPORT
WATERSPORTS LOOK TO THE FUTURE WITH RECYCLABLE EPOXY PARTS

Automotive

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 YDL5540-THR9151 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

LIGHTWEIGHT RESIN SPRAY SOLUTION FOR COMPLEX HONEYCOMB

SUSTAINABLE NONWOVENS
BASED ON RECYCLED CARBON FIBRES

Tenowo produces nonwovens based on recycled carbon
fibres (rCF). The fibres come from edge trim of woven and noncrimp fabric production (with original sizing) or from end-of-life
components (without sizing or just freshly sized).
The fibres used as precursor for the rCF nonwovens are provided by
carbon fibre processing industries as edge trim residues from woven
and non-crimp fabric production. Fibres from end-of-life components
can also be processed into nonwovens.
Tenowo uses two processes to bond carbon fibre nonwovens, which
can be selected according to individual needs: needle punching and
Maliwatt stitch bonding.
In needle punching, several needles with notches punch through the
fibre layers to strengthen the fibres.
Needle-punched nonwovens can be draped very well. Fabric widths
up to 2000 mm and grammages from 100 gsm to 600 gsm can be
produced.
In the field of technical textiles, the stitch-bonding process is already
known for multiaxial fabrics. Stitching improves handling and increases
the maximum tensile forces in the yarn direction of the nonwovens.
Furthermore, the "needle channels" improve the infiltration of resin
during the impregnation process.
The yarn type, stitch length and pattern can be varied. In combination
with this, additional textiles can be applied to the top and/or bottom side
of the fabric. Widths here range up to 1500 mm with grammages from
100 gsm to 350 gsm. www.tenowo.com

Multi-sector

Rimline HC+ resin technology is a new, two-component polyurethane resin system for spray application to fibreglassreinforced honeycomb panels for automotive interior components.
Sprayed onto paper honeycomb covered with a glass fibre mat, the resin technology can be used to create a
lightweight composite material that is strong, rigid, robust and long lasting. Meeting industry needs for VOC and
odour specifications, the resins can enable new design possibilities, delivering panels with intricate mould details and
superior edge finishing.
The use of this resin can also boost plant productivity. This new line of resins has a longer spray window of up to 100
seconds, enabling part producers to spray bigger panels or use the resin in projects where multi-cavity tools are used. The resin will cure in just 35
seconds for simple parts and in around 60 seconds for more complex components.
A high number of parts can be produced, without having to reapply external release agents and without the need for tool cleaning. The resin can help
reduce waste.
The technology is thixotropic enough to eliminate drips when a panel is sprayed on one side and subsequently flipped over. www.huntsman.com

NEW SAERFOAM STYLES
TO REPLACE PVC80

Saertex has developed an updated
version of SAERfoam. Offering an
alternative to existing PVC80 solutions,
the new standard styles SAERfoam80 and
SAERfoam60 offer improved drapeability and
potential cost savings. In addition, SAERfoam+
allows customization of this engineered core material within the SAERTEX
product range.
SAERfoam80 was specified for the vacuum infusion of large structural
parts, such as applications where it is required to walk on the core.
SAERfoam60 is recommended for RTM processes or vacuum infusion
processing of smaller parts.
Both styles offer advantages such as improved drapeability with almost
no rupture during the layup of precut dry materials, as well as fast manual
and CNC cutting. In addition, SAERfoam80 and SAERfoam60 feature
improved rigidity compared to PVC80, making them ideal materials for
the marine market. SAERfoam+ completes the SAERfoam series.
It offers options such as different foam inputs, modifications to the number
and direction of the glass bridge reinforcements, and LEO fire protection.
The SAERfoam series is available in thicknesses from 10mm to 30mm
and is compatible with most common resins from leading manufacturers.
With a very low moisture absorption rate of less than one percent and an
excellent stiffness-to-weight ratio, it is also an alternative for PET115 and
balsa wood 150 materials in many applications.
