From the Sector

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%.

AMAC cooperates with ITA (Institute for Textile Technology of RWTH Aachen University and their ITA GmbH) for the business development in composites 

As of April 19th, 2021, AMAC is pleased to announce its cooperation with the Institute for Textile Technology, ITA, of RWTH Aachen University and their ITA GmbH. The aim of the cooperation is to strengthen and develop their business activities in composites.

ITA, as one of the largest institutes on the campus of the excellence University RWTH Aachen, Germany, develops complete solutions from the manufacturing of the fiber itself over the processing of textile intermediates with thermoplastic and thermoset resins, textile-based part manufacturing, capabilities such as braiding, pultrusion and in-situ impregnation of textile preforms. Top 3 focused industries are transportation and particularly the e-mobility sector, building and construction as well as the wind energy sector. Additionally, ITA GmbH is the partner of the industry in R&D, focusing on 8 business segments, providing technology and knowledge transfer, as well as offering comprehensive solutions along the entire textile value chain.

Prof. Dr. Thomas Gries, Director of ITA, explains the background of the strategic cooperation with focus on composites: „Our long-term experience and unmatched know-how with all aspects of continuous fibers, non-wovens and web-based reinforcements allows us to deliver to the composite manufacturers a complete technology and service offer around the development of technical textiles, from the development of glass and carbon fibers to the textile-based processing of composite parts.

Flax has accompanied people for thousands of years, in linen fabrics, in ropes, as insulation material. And until the present day. With woven tapes made of flax, vombaur makes the functional and ecological advantages of natural fibres available for lightweight design.

Lightweight and firm
Flax fibres are particularly rigid and tear-proof. Textiles made of the natural material therefore give natural fibre reinforced plastic (NFP) special stability. Additionally, flax has a low density. The components thus combine high rigidity and strength with low weight. Another functional plus: natural fibre reinforced plastics are less prone to splintering than glass fibre reinforced plastics.

Sustainable material
The cultivation of flax binds CO2 and the production of NFP generates 33 percent lower CO2 emissions than conventional fibre reinforced plastics. The energy consumption is 40 percent lower. This reduces production costs and improves the material's CO2 footprint. Punch-packing arguments for natural fibre tapes – like flax tape by vombaur – in lightweight design applications.

Circular Economy
Circular Economy – this also works in lightweight design. The number of recycling cycles without loss of quality is higher for natural fibre reinforced plastics than for glass or carbon fibre reinforced plastics: the thermoplastic matrix of the composite can be melted and recycled after a product life cycle. The natural fibres can "live on" in other products – injection moulded products for example.

Versatile applications
"Composites from our flax tapes are used to reinforce high-tech skis as well as for extruding state-of-the-art window sections – the applications are countless," explains Tomislav Josipovic, Sales Manager with vombaur. "As a development partner, we support applications for the automotive, wind energy, construction, sports and many other industries with our composite textiles."

As the first composites trade show worldwide since the Covid-19-crisis, the China Composites in Shanghai (September 2 to 4, 2020) took up its activity. The show counted about 600 exhibitors and over 20 000 visitors, mostly Chinese locals, attended the exhibition.

Chinese Reach Group under the lead of its president Daniel He represented a large portfolio of European companies and their recent developments through their cooperation with Dr. Michael Effing´s AMAC/Germany, among them Airborne (NL), Textechno (D) and Conbility (D).

Daniel He describes the situation: „The Chinese market is picking up again; a price increase of 7% for glass fibers was announced right before the China Composites Show, on August 25th 2020, which was even leading to a temporary material shortage. Today, the most booming industries in China are wind energy, building and infrastructure and innovation for electric cars. Unlike the rest of the world, where the aircraft industry undergoes a deep decline, in China it takes up by 50 %, which is very promising. Furthermore, we expect half a year for a full recovery of the industry, while the China growth of 2020 is still expected to be between 2 and 4 %.“

Michael Effing replied: “Enabling the composites business between China and Europe is the aim of our cooperation with Reach and with our customers, which are active in digital automatization, testing equipment or cost optimization software. We are very happy to have been present in China through our representant Reach and are looking forward to bridge and overcome the Covid-19-crisis with our upcoming event in Germany, the Composites for Europe in Stuttgart in November and hope to be back to full global business speed at the JEC in Paris in 2021.“
