From the Sector

Hypetex®, a leader in colouring carbon fibre materials, is delighted to announce that its Hypetex® Kromaskin™ field hockey stick for adidas has been selected as a finalist for the 2022 JEC Innovation Awards.

Hypetex® was commissioned by adidas to develop a market leading hockey stick differentiated from existing equipment not just by its unique pigmented carbon fibre finish, but also by its game changing hitting power and consistency. The patented range of Kromaskin™ sticks, created with support from project partners Textreme® and Marque Makers, was found to outperform competitors in a benchmark study against eight other premium hockey sticks carried out by Loughborough’s Sports Technology Institute (STI).

Hypetex® lead the design, engineering, materials, and production process development for the adidas field hockey stick project. By incorporating the stick’s finish colour within the outermost carbon fibre layer, the stick mould could be adjusted outwards, placing the highly structural spread tow materials right at the outer extremities of the mould cavity, increasing mechanical performance and maximising the structural benefits of the composite materials used.

Whilst the Kromaskin™ surface provides a stunning depth of colour with minimal finishing required after demoulding, the Hypetex® technology, including an epoxy based expanding microsphere system used in the core, delivers significant performance gains on the hockey pitch. In tests at the STI, adidas Kromaskin™ sticks had up to 16% higher coefficient of restitution (COR), meaning they will return more energy and the ball will travel faster. In addition, through the production led design and materials used, the variation in COR was 70% less than the other sticks on test, a significant reduction in the production inconsistencies common with the manufacturing of performance sporting goods.

Microplastic pollution is a global challenge across many industries and sectors – one of critical importance being textiles.

A 2021 study by the California Ocean Science Trust and a group of interdisciplinary scientists acknowledges that microfibres from textiles are among the most common microplastic materials found in the marine environment. Every time synthetic clothes are manufactured, worn, washed, or disposed of, they release microplastics into terrestrial and marine environments, including human food chains. Synthetic fibres represent over two-thirds (69%) of all materials used in textiles, a proportion that is expected to rise to 73% by 2030. The production of synthetic fibres has fuelled a 40-year trend of increased per capita clothing consumption.

Global textile consumption has become:

• more reliant on non-renewable resources,
• less biodegradable, and
• increasingly prone to releasing microplastics.

The increased consumption is also discretionary, driven by consumer desire and remains unchecked. Thus, the long-term trend in the textile industry parallels the intentional addition of microplastics to products such as cosmetics. The contrast is that the European Chemicals Agency (ECHA) has recommended such intentional additions be restricted, whereas the over-consumption of synthetic fibres continues unchecked. One way for the EU to account for and mitigate microplastic pollution is through an EU-backed methodology measuring and reporting microplastic emissions, so that consumers and procurement officers have the information needed to minimise microplastic pollution resulting from their purchasing decisions.

There is a critical opportunity to address microplastic pollution in the fashion textile industry through the EU Product Environmental Footprint (PEF) methodology. To meet the environmental objectives of the Circular Economy Action Plan, the EU is proposing that companies substantiate their products’ environmental credentials using this harmonised methodology. However, microplastic pollution is not accounted for in the PEF methodology. This omission has the effect of assigning a zero score to microplastic pollution and would undermine the efforts of the European Green Deal, which aim “to address the unintentional release of microplastics in the environment.”

The incorporation of microplastic pollution as an indicator would increase the legitimacy of the PEF method as well as better inform consumer purchasing decisions, especially as the European Green Deal seeks to “further develop and harmonise methods for measuring unintentionally released microplastics, especially from tyres and textiles, and delivering harmonised data on microplastics concentrations in seawater.”

Whilst we continue to learn about the damage of microplastics and there is new knowledge emerging on the toxic impacts along the food chain, there is sufficient information on the rate of microplastic leakage into the environment to implement a basic, inventory level indicator in the PEF now. This is consistent with the recommendations of a review of microplastic pollution originating from the life cycle of apparel and home textiles. There are precedents in PEF for basic level (e.g., ‘resource use, fossils’) and largely untested (e.g. land occupation and toxicity indicators) indicators, and therefore an opportunity for the EU to promote research and development in the measurement and modelling of microplastic pollution by including such emissions in the PEF methodology. For such an indicator, the long and complex supply chains of the apparel and footwear industry would be a test case with high-impact and a global reach.

10 years after the installation of the photovoltaic plant in the production units in the Biellese region, the Marchi & Fildi Group takes stock of the operation and publishes the data on energy produced, consumed, and fed back into the grid.

The photovoltaic plant owned by the Group is made up of 11,385 modules divided between the three facilities in Biella (Production), Cerrione (Dyeing mill) and Verrone (Logistics), which in total cover a surface of 16,515 sq.m.

The balance to be drawn from these 10 years is a positive one: in total 22,974,828 kWh have been produced, of which 7,292,027 kWh have been used in company activities, with a saving in energy costs of approximately €1m over 10 years.  

The energy kWh produced and not used by the company was fed back into the grid and corresponds to the average annual consumption of around 4630 families.*

The Marchi & Fildi Group has always been committed to rationalising electric energy consumption with the aim of contributing towards an eco-sustainable development without compromising the rate of production and the ability to grow. In addition to producing its own electric energy, over the years, the company has also achieved an increasing number of Energy Efficiency Titles (TEE), otherwise known as white certificates. In 2021, 138 TEEs have been awarded as a result of such interventions as the introduction of LED lighting and the optimisation of the production processes which, while still as efficient as before, permit the company to reduce the electric energy consumption of the machinery.

*In the meter class for the range of 3kW to 4.5 kW, the average consumption for residential properties is the equivalent of 3,382 kWh (source: Arera Relazione annual state of services for the year 2020). The calculations are the results of an internal study conducted by the Marchi & Fildi Group.

Hexcel, a global leader in advanced composites technologies, announces the successful maiden flight of a lightweight camera drone, developed using Hexcel HexPly® carbon fiber prepregs. The composite drone was developed by a team of students from the University of Applied Sciences Upper Austria in Wels with composite materials supplied by Hexcel Neumarkt in Austria.

A team of six students in the university’s lightweight construction and composite materials course was responsible for the complete design, engineering, and manufacture of the camera drone over a period of 18 months. Hexcel materials and optimization of the composite engineering enabled the team to reduce the composite structural mass by an impressive 42% compared to similar drones.

Hexcel Neumarkt was one of eight industrial partners supporting the university team throughout the project, providing all carbon fiber prepreg materials used for the drone’s landing gear as well as the fuselage. The ultra-lightweight 32g landing gear was laid up and cured in the press, whereas the fuselage was autoclave cured by the student team using Hexcel HexPly M901 and HexPly M78.1 prepreg resin systems with a combination of woven and unidirectional carbon fiber reinforcements.

With the development of Unmanned Aerial Vehicles (UAV) as a key emerging market and innovation space in the transportation sector, Hexcel’s collaboration with the University of Applied Sciences Upper Austria team not only creates an important link with the next generation of lightweight composite engineers but also highlights the weight saving and structural benefits of Hexcel composite material solutions.

"The massive weight saving achieved with their updated version of the camera drone is a fantastic achievement by the student team," said Michael Rabl, Dean of FH Wels of the Upper Austria University of Applied Sciences. "The joint study not only illustrates the wide range of complex and innovative composite techniques present in the drone sector but also presents the opportunities that exist for further development in the wider Urban Air Mobility (UAM) and aerospace composites markets.”

Hexcel congratulates the project team which includes Lukas Weninger, Karl-Heinz Schneider, Jakob Schlosser, Matthias Thon, Marla Unter, and Simone Hartl on an exceptional piece of lightweight composite design and thanks them for showcasing the contribution of Hexcel materials with a presentation and drone flight. Johanna Arndt, research and technology group leader at Hexcel Neumarkt, said, “It was a great pleasure to work with the team who were very cooperative and self-motivated to succeed. Watching the drone just fly around the Neumarkt plant was just great.”

Hexcel manufactures a complete range of carbon fibers, dry carbon UD tapes, specialty reinforcements, prepregs, and honeycomb core materials, providing customized manufacturing options for new UAM applications that combine aerospace reliability with the high-rate production required. Hexcel composite materials are the ideal solution for the lightest and most efficient cost-competitive transportation vehicles of the future.
