KARL MAYER GROUP with sustainable technical textiles at ITMA

KARL MAYER GROUP will be presenting a WEFTTRONIC® II G at the ITMA with new features and upgrades for greater efficiency. This warp knitting machine with weft insertion produces lattice structures from high-strength polyester, which are firmly established in the construction industry in particular. With a working width of 213", it offers productivity and further advantages through design innovations. New features include weft thread tension monitoring, management and the new VARIO WEFT laying system. The component for the weft insertion aims at maximum flexibility. It allows the patterning of the weft yarn to be changed quickly and easily electronically, without mechanical intervention during yarn insertion and without limits on repeat lengths. In addition, there is less waste.

The KARL MAYER GROUP also supports its customers with well thought-out Care Solutions. The new support offers include retrofit packages for retrofitting control and drive technology for weft insertion and composite machines, and service packages that bundle various services. These include machine inspections and the replacement of all drive belts. The customer benefits from fixed prices that cover the costs of technician assignments, various discount options and transparent services.

A new solution for the vertical greening of cities is presented from the field of application for technical textiles. The core of the innovation is a grid textile produced on warp knitting machines with weft insertion by KARL MAYER Technische Textilien GmbH. The knitted lattice fabric is made of flax. It is used as a climbing aid for fast-growing plants, and after the greening phase, in autumn, it can be recycled together with these plants as biomass in pyrolysis plants to produce electricity and activated carbon. In summer, the planted sails lower the ambient temperature through evaporation effects. In addition, photosynthesis creates fresh air and binds CO2. Other important advantages are low soil requirements and flexible placement in public spaces. The greening system was developed by the company Micro Climate Cultivation, OMC°C, with the support of KARL MAYER Technische Textilien.

The KARL MAYER GROUP will also be exhibiting a sustainable composite solution made from natural fibres. The reinforcing textile of the innovative lightweight material is a multiaxial non-crimp fabric, which was also produced from the bio-based raw material flax on a COP MAX 4 from KARL MAYER Technische Textilien. The boatbuilding specialist GREENBOATS uses natural fibre composites to achieve sustainable products. The fact that it succeeds in this is shown, for example, by the Global Warming Potential (GWP): 0.48 kg of CO2 per kilogram of flax reinforcement compares with 2.9 kg of CO2 per kilogram of glass textile.

GREENBOATS, Sicomin and Bcomp Selected as JEC Innovation Awards 2021 Finalists

GREENBOATS, Sicomin and Bcomp are nominated as finalists for the JEC Innovation Awards 2021. The three project partners have been selected as finalists in the awards’ Renewable Energy category for their innovative Green Nacelle – the first offshore nacelle manufactured with natural fibre composites (NFC).

The Green Nacelle was designed by NFC innovators GREENBOATS, who were also responsible for the structural engineering, manufacturing and assembly of the nacelle.  By incorporating Bcomp’s ampliTex™ flax reinforcements, FSC certified balsa wood cores and bio-based resins, the Green Nacelle’s NFC construction saves approximately 60% CO2 equivalent and reduces the energy consumption by over 50% compared to a nacelle made with existing GFRP technology.

In addition to the lower CO2 footprint, the natural fibre composite structure also introduces viable options for the end of the nacelles’ life unlike traditional GFRP structures - an issue of increasing concern for the wind energy sector that presents a great opportunity for natural fibre composites to bring a sustainable change to this market.

Sicomin, the formulator and supplier of the leading range of GreenPoxy bio-based epoxy resin systems, supplied its DNV GL approved InfuGreen 810 resin system that was used to infuse the Green Nacelle’s main structural sandwich panels, as well as providing intumescent FR gelcoats, bio-based laminating resins and UV resistant clear coatings for the groundbreaking new nacelle.  Materials, as well as on-site technical support, were delivered by Sicomin’s German distributor TIME OUT Composites.

The winners of the awards will be announced during JEC Connect which will be held on the 1st and 2nd June 2021.

Sicomin: Collaboration with GREENBOATS® for natural fibre composite

Sicomin announces its latest collaboration with GREENBOATS® as they deliver the first ever natural fibre composite (NFC) nacelle for an offshore wind turbine.  

With more than 2.5 million tons of composite materials in use in the wind industry globally, and the first generation of wind turbines now approaching end of life, there is still a lack of well-established recycling options. GREENBOATS’ mission is to demonstrate how large-scale NFC structures in wind energy can lower energy consumption in manufacturing and significantly improve the sustainability of the composite materials used in the turbine.

In 2020, GREENBOATS was commissioned by a leading wind energy technology developer to design and manufacture a sustainable NFC nacelle. The resulting 7.3m long structure has a surface area of approximately 100m2 and was engineered by GREENBOATS to satisfy all DNV-GL load cases required for an offshore turbine nacelle, including 200km/h max wind loads and 2KN loads on the guard rails.

Sicomin’s market leading GreenPoxy® range met these challenging engineering requirements, with the company’s recently expanded manufacturing capability also matching the potential supply volumes required by wind turbine manufacturers.  

Sicomin’s DNV-GL type approved bio-based epoxy was used to infuse BComp flax fibre reinforcements and balsa cores, with Sicomins’ intumescent weatherproof gelcoat applied on the outer surface. Cured panels were cut to shape, formed over a male plug and bonded together, before flax reinforcement plies, hand laminated with GreenPoxy resins and vacuum bagged, were added along all the panel joints lines.  Finally, Sicomin’s highly UV resistant clear coating products were used to protect and enhance the finish of the flax fibre feature stripe details.

Bio Fire Retardant Epoxy Gelcoat for Wind Energy and Infrastructure
Sicomin will showcase SGi 128, an innovative intumescent epoxy gelcoat developed specifically for fire retardant coating applications for critical components found in the Wind Energy and Civil Engineering markets.
SGi 128 Gelcoat is produced with 38% of its carbon content derived from non-oil sources and is a halogen free gelcoat that provides outstanding fire protection for epoxy laminates and extremely low smoke toxicity. Available with both fast and slow hardeners, this easy to apply epoxy system forms a much tougher and waterproof part surface than traditional intumescent coatings. Sicomin’s SGi 128 is available in industrial volumes with short lead times and has been successfully tested to EN 13501 (EUROCLASS B-S1-d0) and ASTM E84 (Class A).

NEW Bio Resin for HP-RTM processing for Automotive
Sicomin’s new bio-resin specifically formulated for HP-RTM processing, SR GreenPoxy® 28, is the sixth product in Sicomin’s renowned GreenPoxy® range. SR GreenPoxy® 28 is a fast cycle, low toxicity, third generation bio-based formulation aimed specifically at the HP-RTM moulding processes used for both high performance Automotive structural parts and aesthetic carbon fibre components. The new formulation has been optimized for fast production cycle times and superior mechanical performance and is a more sustainable alternative to traditional resins providing exceptional performance and quality for high volume programmes.
