From the Sector

Fibres, fabrics, epoxy resins and adhesives from Sicomin have been used by Grand Largue Composites (GLC) to construct the first Class40 racing yacht to feature a significant quantity of flax-fibre reinforcements.
The yacht, called Crosscall, won the Class40 World Championships in June 2022 and is a prototype of the new Lift V2 design by Marc Lombard, one of the leading naval architects in this field.

Class40 is one of the most competitive fleets in yacht racing. The hulls of Class40 yachts must be light in weight, strong and stiff, and durable in the most extreme of conditions. Furthermore, to keep costs down, they cannot be reinforced with carbon fibres. The quality and reliability of the resins used for the infusion and lamination of the hulls are therefore of paramount importance.

Crosscall's cockpit was designed to be effectively non-structural, with the mainsheet, which can generate huge shock loads, supported separately. This would allow the cockpit to be made from a hybrid biaxial fabric comprising 50% flax fibres. Other parts of the boat that incorporate flax fibre include the tunnel, the engine cover, the ballast tanks and the cap. The rest of the boat is reinforced with 100% glass-fibre fabrics.

To help it realise this ambitious design, GLC, an infusion specialist, turned to its long-time material supplier, Sicomin. The hull was moulded and infused in one piece and the deck – including the hybrid flax-fibre cockpit – was also infused as a single part. The internal structure was then laminated into the hull by hand before the hull and deck were finally bonded together.

The infusion resin selected was Sicomin’s SR 1710, a high-modulus structural epoxy. Designed specifically for use in infusion and injection processes, it has exceptionally low viscosity and its low-reactivity hardener makes it suitable for the production of large parts. Composites components made from SR 1710 possess high interlaminar shear-strength and the resin retains its mechanical properties in wet environments.

Sicomin’s low-toxicity SR 8200 was used to laminate the internal structures onto the skin of the hull. Ideal for hand laminating, this system includes a choice of hardeners with a wide range of reactivities, which makes it equally suitable for making large or small parts. The hull and deck were joined together with Sicomin’s Isobond SR 7100, which demonstrates high fatigue strength and is very resistant to microcracking.

An epoxy bonding primer – called Undercoat EP 215 HB+ and supplied by Sicomin’s sister company, Map Yachting – was applied to the moulds first to make demoulding easier. It also serves as an undercoat in the polyurethane exterior paint system that is used instead of gelcoat to protect the epoxy hull from UV damage.

Since the launch of Crosscall, GLC has started building a second Lift V2 Class40 and a third one is now planned, both for which Sicomin will supply the materials.

• Strategic partnership for automation system in the field of slot dies and coextrusion adapters

Reifenhäuser Extrusion Systems (RES) - the Reifenhäuser Group's business unit specializing in extrusion components - announces a strategic partnership with maku AG at K 2022, the world's largest plastics trade fair. The aim of the cooperation is the joint marketing and further development of the automation system designed by maku for coextrusion adapters and slot dies.

The so-called PAM system (precise, autonomous, mechatronic) is available immediately and exclusively as an automation option for new Reifenhäuser dies and adapters, as well as for aftermarket dies across all manufacturers. PAM enables producers in the field of flat film and sheet production as well as extrusion coating to precisely control the entire hot part (coextrusion adapter and die) via the line's control panel. This is significantly faster and more accurate than conventional control by hand or expansion bolt automation. It enables faster start-up of good production, higher output with lower energy consumption, and thus significantly improved overall equipment efficiency (OEE). The decisive advantage lies in the use of motorized manual adjustment bolts that replace conventional thermal expansion bolts. Reifenhäuser presented the system for the first time at the K 2022.

Perstorp has been acquired by PETRONAS Chemicals Group Berhad (PCG), Malaysia´s leading integrated chemicals provider and part of PETRONAS Group, on 11 October 2022.

In May this year, PCG signed a Securities Purchase Agreement with Financière Forêt S.à.r.l, a company under PAI Partners, a European private equity firm, to acquire the entire equity interest in Perstorp, a leading sustainability-driven global specialty chemicals company based in Sweden. With the completion of the acquisition, Perstorp is now PCG’s wholly-owned subsidiary.

PCG will strive to ensure the timely completion of Perstorp’s growth projects in a safe and cost-effective manner. Perstorp has several projects lined up in the near future, including the launch of Project Air which aims to reduce carbon emissions through the production of sustainable methanol. Recently, The European Union Innovation Fund selected Project Air, as one of the 17 large-scale green tech projects, which together will be granted more than EUR 1.8 billion. Project Air is a gamechanger for the chemical industry, moving from fossil raw materials to recycled and bio-based feedstock, thereby enabling sustainable chemical products to a large variety of industries and end products. At full capacity, it will reduce global CO2 emissions with close to 500,000 metric tons per year from today’s levels, corresponding to one percent of current emissions in Sweden.

Pincroft, UK’s largest textile dyer, printer and finisher, developed a new camouflage pattern for the Dutch Ministry of Defence as part of their Defensie Materieel Organisatie’s (DMO) ‘STRONG’ programme that aims to supply combat clothing and equipment to all military personnel part of the Royal Netherlands Navy, Army, Air Force and Marechaussee.

The new fabric and camouflage pattern boast the new Netherlands Fractal Pattern and will be used in at least 480,000 sets of uniforms for soldiers worldwide. The camouflage pattern is being manufactured in a green or woodland style for the Army, Air Force, Marechaussee and Marines, while the Navy receives a blue or marine style design. Pincroft followed the guidelines of the new Netherlands Fractal Pattern (NFP) to create an eight-colour camouflage design that provides high levels of disruption to give soldiers better concealment when needed.

The fabric was created by global workwear textile manufacturer, Carrington Textiles, specifically following the Dutch MoD’s requirements on comfort and protection. The result is a lightweight yet durable textile of 210gsm with a composition of 50% cotton, 50% high tenacity nylon and Ripstop for added strength.

The high cotton content of the fabric creates a uniform that’s comfortable to wear due to its softness to the touch, and breathability, as well as providing moisture wicking properties, key elements for the tough conditions soldiers work in. The addition of high tenacity nylon to the fabric, provides added strength and durability, with the Ripstop properties of the fabric offering tear resistance.

Around 480,000 trousers and jackets will be delivered to officers from the Royal Netherlands Navy, Army, Air Force and Marechaussee, during a uniform roll out part of the Dutch MoD’s ‘STRONG’ programme that aims to equip the armed forces in the next 18 months with versatile uniforms and equipment that are adjustable according to the assignment. The pack also includes a raincoat, combat shirt and baseball cap.

The future of e-mobility will be determined in particular by safe battery enclosures. As batteries for electric vehicles become more performant, higher volumetric energy density plays a crucial role. If more energy is to be stored in less installation space, new material and design solutions are required. The development of suitable enclosures made of safe and highly robust lightweight materials is also required. This is a case for the Aachen Centre for Integrative Lightweight Production (AZL). A project on cell-to-pack battery enclosures for battery-electric vehicles, which has been eagerly awaited in the industry, will start in October this year there.

The design of battery housings is crucial for safety, capacity, performance, and economics. The Cell-to-Pack project, which is starting now, will focus on developing concepts for structural components and for producing them based on a variety of materials and design approaches. The concepts will be compared in terms of performance, weight and production costs, creating new know-how for OEMs, producers and their suppliers throughout the battery vehicle value chain. Companies are now invited to participate in this new cross-industry project to develop battery enclosure concepts for the promising and trend-setting cell-to-pack technology.

The basis for the project is the lightweight engineering expertise of the AZL experts, which they have already demonstrated in previous projects for multi-material solutions for module-based battery housings. Together with 46 industry partners, including Audi, Asahi Kasei, Covestro, DSM, EconCore, Faurecia, Hutchinson, Johns Manville, Magna, Marelli and Teijin, 20 different multi-material concepts were optimized in terms of weight and cost and compared with a reference component made from aluminum. All production steps were modelled in detail to obtain reliable cost estimates for each variant. Result: depending on the concept, 20% weight or 36% cost savings potential could be identified by using multi-material composites compared to the established aluminum reference.

It is expected that the design concept of battery enclosures will develop in the direction of a more efficient layout. In this case, the cells are no longer combined in modules in additional production steps, but are integrated directly into the battery housing. The elimination of battery modules and the improved, weight-saving use of space will allow for higher packing density, reduced overall height and cost saving. In addition, various levels of structural integration of the battery housing into the body structure are expected. These new designs bring specific challenges, including ensuring protection of the battery cells from external damage and fire protection. In addition, different recyclability and repair requirements may significantly impact future designs. How the different material and structural options for future generations of battery enclosures for the cell-to-pack technology might look like and how they compare in terms of cost and environmental impact will be investigated in the new AZL project. In addition to the material and production concepts from the concept study for module-based battery enclosures, results from a currently ongoing benchmarking of different materials for the impact protection plate and a new method for determining mechanical properties during a fire test will also be incorporated.

The project will start on October 27, 2022 with a kick-off meeting of the consortium, interested companies can still apply for participation until then.

• Exceptional achievement of research work on the use of Nuclear Magnetic Resonance (NMR) spectroscopy for understanding PET depolymerization enzymes

Carbios (Euronext Growth Paris: ALCRB), a pioneer in the development of enzymatic solutions dedicated to the end-of-life of plastic and textile polymers, announces the publication of an article entitled “An NMR look at an engineered PET depolymerase” in the scientific journal Biophysical Journal.

The article describes the use of Nuclear Magnetic Resonance (NMR) spectroscopy to study the thermal stability of PET depolymerization enzymes and the mechanism of adsorption of the enzyme on the polymer. This innovative approach, which required months of development, is a world first and opens up new ways of improving these enzymes. This publication confirms Carbios' international lead in the development of the most efficient enzymes for the depolymerization and recycling of plastics.

Prof. Alain Marty, Chief Scientific Officer of Carbios and co-author of the article, explains: “ Nearly 25 researchers are currently working on our unique enzymatic technology. It is based on academic collaborations with the world's leading experts in their fields..”

Dr. Guy Lippens, CNRS Research Director and co-author of the artcle, adds: “Nuclear Magnetic Resonance (NMR) is an extraordinary biophysical technique for visualizing an enzyme directly in solution. Our study is the first to use NMR as a complementary technique to crystallography and molecular modeling to observe a PETase. This gives new perspectives to better understand the functioning of these enzymes and it makes it possible to imagine new ways of improving these enzymes. ”
