From the Sector

The 17th World-Pultrusion-Conference (WPC) took place in Hamburg from 29 February to 1 March. Pultrusion, also known as the extrusion process, is a highly efficient method for producing fibre-reinforced plastic profiles for various applications in the construction/infrastructure and transport sectors.

A record number of almost 150 participants from all over the world attended the event. An international audience of experts from Europe and the USA, as well as China, India and Japan was represented.

The lecture programme with a total of 25 specialist lectures was strongly characterised by the topic of sustainability. The process development of thermoplastic pultrusion and applications in wind energy, solar panels, bridge construction and the automotive industry were also discussed at length. Despite the difficult market environment, many opportunities and possibilities for the pultrusion industry were presented.

The conference takes place every two years in a European country of importance to the pultrusion industry and is organised by AVK for the European Pultrusion Technology Association (EPTA), in cooperation with the American Composites Manufacturers Association (ACMA).

Felix Pohlkemper and Tim Röding from Institut für Textiltechnik (ITA) of RWTH Aachen University are developing a technology with their start-up CarboScreen GmbH that makes complex carbon fibre production controllable through sensor monitoring. With the help of CarboScreen technology, it should be possible to double the production speed from the current 15 m/min to 30 m/min in the medium term. The doubling of production speed alone could result in an increase in turnover of up to €37.5 million per year and production plant. Felix Pohlkemper and Tim Röding were awarded third place in the AVK Innovation Award 2023 in the Processes and Procedures category for this ground-breaking development. The award ceremony took place during the JEC Roof Forum in Salzburg, Austria.

The production of carbon fibres is highly complex. In the current state of the art, however, the manufacturing process is only monitored manually by semi-skilled workers. However, even minimal fibre damage during production leads to a reduction in the quality of the carbon fibre. In extreme cases, it can also lead to plant fires. To ensure production quality, the production speed is currently limited to a maximum of 15 m/min. In fact, the production speed of the systems could be higher. The sensor-based online monitoring of Carbo-Screen makes it possible to increase the production speed to 30 m/min in the medium term. As a result of the increased production volume per system, the specific production costs of the carbon fibre are reduced, which can result in lower prices.

A reduced sales price would make it possible to use carbon fibres and their composite materials even more widely in traditional markets such as aerospace technology and wind energy, as well as for mass production in the automotive industry.

The CarboScreen online monitoring system is currently being developed for industrial use. It is to be validated at an industrial plant in 2024. CarboScreen GmbH was founded as part of EXIST funding and offers AI-supported sensor systems for carbon fibre production. The sensor technology continuously monitors the fibre throughout the entire production process. Deviations are detected automatically.

The winners of the AVK Innovation Award are honoured annually by the AVK Industrievereinigung Verstärkte Kunststoffe. Companies, institutes and their partners are honoured in three categories: products and applications, processes and procedures, and research and science.

• Sales increase of 12.8% to €1,135.9 million
• EBITDApre improves by 23.4% to €172.8 million
• Net financial debt reduced from €206.3 million to €170.8 million
• Fiscal 2023 expected to be investment and stabilization year

SGL Carbon was again able to improve sales and earnings in fiscal year 2022 following 2021. All four business units contributed to this success.
Sales in fiscal 2022 increased by 12.8% year-on-year to €1,135.9 million (previous year: €1,007.0 million). The rise in sales was mainly due to both volume effects and the successful implementation of pricing initiatives to compensate higher raw material, energy and transport prices. At 23.4%, adjusted EBITDA (EBITDApre) improved at a higher rate than sales and amounted to €172.8 million in fiscal 2022 (previous year: €140.0 million). Increased sales and the associated higher capacity utilization also contributed to the improvement in earnings, as well as focusing on market segments with higher margin potential.
 
Earnings development of SGL Carbon
The increase in EBITDApre by €32.8 million to €172.8 million was mainly driven by the Graphite Solutions business unit (+€30.6 million). The Composite Solutions (+€7.9 million) and Process Technology (+€5.2 million) business units also contributed to the improvement in profitability. Although the Carbon Fibers business unit was able to offset the loss of a lucrative supply contract with an automotive customer in terms of sales with new orders from the wind energy sector, but these sales showed a significantly lower margin level. Accordingly, EBITDApre of this business unit decreased by €11.2 million to €43.2 million (previous year: €54.5 million).

Taking into account net one-off effects and non-recurring items of €8.9 million (previous year: €30.7 million) and depreciation and amortization of €60.8 million (previous year: €60.3 million), reported EBIT amounted to €120.9 million (2021: €110.4 million). This corresponds to an increase of 9.5%.
As a result of the pleasing business performance, the successes of the transformation and non-operating one-off effects and non-recurring items (€8.9 million), a positive Group’s net profit of €126.9 million (previous year: €75.4 million) was achieved in 2022. It should be noted that consolidated net income includes tax income of €31.3 million (previous year: minus €6.2 million). This development is mainly due to valuation adjustments on deferred tax assets amounting to €41.8 million, based on the good business development combined with positive earnings prospects in the USA. Current tax expenses amounted to €11.4 million in 2022 (previous year: €11.9 million).
 
Net financial debt and equity
In fiscal 2022, net financial debt was reduced significantly by 17.2% to €170.8 million compared with the end of 2021 (€206.3 million). The main reason for the decrease is the repayment of financial liabilities in the amount of €29.0 million. Free cash flow decreased from €111.5 million to €67.8 million in 2022. In this context, it should be taken into account that in the previous year, free cash flow included cash inflows of €30.6 million from the sale of land not required for operations.
After 2021, the equity ratio increased again to 38.5% at the end of 2022 (previous year: 27.0% I 2020: 17.5%). Due to the significantly improved earnings situation, the return on capital employed (ROCE) also rose from 8.0% in the previous year to 11.3% in 2022.
 
Development of the business units
As the largest business unit with a share of Group sales of around 45%, Graphite Solutions contributed €512.2 million to Group sales in 2022 (previous year: €443.6 million). The 15.5% increase in sales is based in particular on the positive development of the important market segments Semiconductor & LED and Industrial Applications. Compared to the previous year, sales to customers in the semiconductor & LED industry increased by 49.6%, driven in particular by increasing demand of materials and components for the production of silicon carbide-based high-performance semiconductors. Combined with the increase in sales, GS EBITDApre improved by 34.8% to €118.5 million (previous year: €87.9 million). Accordingly, the EBITDApre margin increased from 19.8% to 23.1%. Volume effects due to higher sales as well as margin effects from the product and customer mix had a positive impact.  Especially the higher sales with customers from the semiconductor industry should be taken into account.

In fiscal 2022, the Process Technology (PT) business unit benefited from the good order situation in recent months and increased its sales by 21.9% to €106.3 million. The main clients of the PT business unit are customers from the chemical industry. The positive development of PT is also reflected in EBITDApre which rose from €4.7 million in the same period of the previous year to €9.9 million. Higher capacity utilization and the successful passing on of increased raw material costs led to an improvement in the EBITDApre margin from 5.4%  to 9.3% in 2022. Energy costs play only a minor role at PT.

In the reporting year, sales of the Carbon Fibers (CF) business unit increased by 3.0% to €347.2 million (previous year: €337.2 million). It should be noted that CF had to absorb the scheduled expiry of a supply contract with an automotive customer at the end of June 2022. These sales were offset by orders from the wind industry and Industrial Applications. However, EBITDApre in the CF division decreased by 20.7% year-on-year to €43.2 million (previous year: €54.5 million). This earnings development is mainly attributable to the expiry of the high-margin automotive contract. In addition, a special effect from energy derivatives in the amount of minus €9.2 million impacted CF earnings in the 1st quarter of 2022. However, the implemented energy price hedges enabled the business unit to maintain its production capability throughout the entire fiscal year, that the weakening of earnings was mitigated.
The Composite Solutions (CS) business unit confirmed its upward trend in fiscal 2022 with a 25.0% increase in sales to €153.1 million (previous year: €122.5 million). The most important market segment for the CS business unit is the automotive industry. In line with the highly positive business performance, EBITDApre of CS increased by 65.3% to €20.0 million (previous year: €12.1 million). This figure also includes non-recurring positive effects of €3.7 million from compensation payments received from automotive customers for premature project terminations.

The non-operating Corporate segment contributed €17.1 million to Group sales (previous year: €16.5 million). In line with continued strict cost management as part of the transformation, EBITDApre improved slightly to minus €18.8 million (previous year: minus €19.2 million).

Outlook
"If we summarize our expectations for the 2023 financial year, it can be summed up under the guiding principle: -invest and stabilize," CFO Thomas Dippold comments on the forecast for 2023.
For the fiscal year 2023 we continue to expect solid demand for our materials and products. In particular, we expect that the demand for special graphite products for high-temperature processes, e.g. in the semiconductor, solar and LED industries, will continue to increase. On the other hand, the first-time full-year effect from the expiry of a supply contract with an automotive customer in the carbon fiber segment and the sale of our business in Gardena (USA) will burden sales development.

"The increasing demand for high-performance semiconductors for electromobility or renewable forms of energy will also boost the demand of components made of graphite for the production of these semiconductors. To benefit from the related opportunities, we will expand our production capacities in this segment and invest a double-digit million amount in 2023 . Based on existing supply relationships, we will implement this investments partly together with our customers," explains CEO Dr. Torsten Derr.
On the cost side, we expect energy and raw material prices to remain at a high level in 2023, along with significant wage increases. Our forecast implies that higher factor costs can be partially passed on to customers through price initiatives.
Based on the assumptions described, we expect Group sales to be at prior-year level and EBITDApre to be between €160 million and €180 million in the financial year 2023.
In the medium term (until 2027), we anticipate a further improvement in our EBITDApre margin between 18% and 19%.

• Natural fibers combined with bio-derived epoxy resins provide sustainable options for Industrial markets

Hexcel has developed a new product range that combines Hexcel resin systems made with bio-derived resin content with natural fiber reinforcements to create material solutions for Automotive, Winter Sports, Marine and Wind Energy applications.

HexPly Nature Range includes proven resins such as HexPly M49, M78.1-LT and M79 but with bio-derived epoxy resin content. The excellent resin characteristics remain unchanged in the new Nature Range products, maintaining high mechanical performance and consistent processing properties.
In addition, the HexPly Nature Range provides prepreg options with natural fiber reinforcements that can be seamlessly integrated into existing production processes.

Hexcel worked with TÜV Austria to provide independent, high-quality measurement and assessment of the bio-content of HexPly Nature Range products. TÜV Austria’s OK biobased certification uses a standardized measurement of the biobased carbon content enabling transparency and easy like-for-like comparison between products.

At JEC World in Paris on May 3-5, Hexcel presented an alpine ski produced by the Tecnica Group Ski Excellence Center which produces skis for Blizzard and for Nordica using HexPly Nature Range M78.1-LT UD flax fiber prepreg. In addition to providing a bio-based material solution, the natural fiber-reinforced prepreg also offers the potential to improve impact performance and vibration damping in the ski.

Claude Despierres, VP of Sales and Marketing – Industrial at Hexcel, said, “Our new HexPly Nature Range forms an important part of providing customers with biobased, TÜV-certified material options based on our established prepreg resin systems. Marine, winter sports, wind energy and automotive manufacturers can now have the choice to switch from petroleum-based material solutions to Hexcel HexPly Nature Range with no compromise in performance or process efficiency.”

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.
