Fibre-reinforced materials for next-generation space missions

A new generation of space materials left Earth November. 5 as they head to the International Space Station (ISS) to undergo testing in the brutal conditions of low Earth orbit.

Developed at the University of Bristol, these high-performance materials could be used to build future space stations, spacecraft for interplanetary travel or a new ISS.

They will be placed on the Bartolomeo platform, located on the front of the ISS, where they will orbit Earth up to 9,000 times over the next 12 to 18 months at speeds of 17,000 mph.

The carbon fibre reinforced composites will need to survive temperatures between -150ºC and +120ºC, space debris travelling seven times faster than a bullet, severe electromagnetic radiation, high vacuum and atomic oxygen, which erodes even the toughest materials.

Prof Ian Hamerton, Professor of Polymers and Sustainable Composites in the University of Bristol’s world-leading Bristol Composites Institute, said:

Prof Ian Hamerton, Professor of Polymers and Sustainable Composites in the University of Bristol’s world-leading Bristol Composites Institute, said:  

“Space is the most challenging environment for which to design new materials. You’re pitting your materials expertise, skills and ingenuity against extremes of temperature, mechanical stress, radiation, high speed impacts and more.

“Any one of those might be difficult, and, unfortunately, gaining access to repair them is not an easy option, so the materials we build must survive without maintenance.  

“The opportunity to test our materials in the proving ground of space is priceless and will help our University of Bristol scientists on the ground improve fibre-reinforced materials for next-generation space missions.”

There are four laboratory-made polymers heading to the ISS, each of which has been reinforced with carbon fibres and two contain nanoparticles. All four are the result of University of Bristol research and one is patented.

 If the materials cope in the harsh environment, they could be used to create longer-lasting space components, allowing spacecraft to travel further, and spend more time in space.

Future communities on new planets will need protection against galactic cosmic radiation. Dr Ali Kandemir, Senior Research Associate at the University of Bristol, is one of several Bristol researchers, supported by the UK Space Agency (UKSA), examining the effects of simulated galactic cosmic radiation on the materials, in a European Space Agency (ESA) project.

Dr Kandemir said: “We want materials that are resilient in the space environment and, importantly, materials that can shield humans from that radiation.

“We also want to make these materials sustainable, so that when they reach the end of their life they can be recycled and used again for the same purpose.”

The launch of the Space X Dragon CRS-2 spacecraft this morning is the culmination of five years of work for Prof Hamerton and his team.

It has included the efforts of early career researchers, postgraduates and several Aerospace Engineering undergraduates at the University of Bristol, whose final year research projects have been linked to the space materials project.

The practical support of the University of Bristol-hosted National Composites Centre (NCC) was crucial to the scale up of the composite materials.

Prof Kate Robson Brown, Vice-President for Research, Innovation and Impact at University College Dublin, and a collaborator on the project, said:

“After nearly five years of research to develop novel composite materials for space applications it is very exciting to see our experiment launch to the International Space Station.

“I am proud to be part of this mission, and to be working with the multidisciplinary and multisector research team to deliver integrated real world and digital testing for innovative materials which will help to drive growth in the new space economy.

“This mission also demonstrates how space research funding creates career changing opportunities for early career researchers and PhD students in a sector of huge value to both Ireland and the UK.”

Funding to support the project was supplied by the ESA, the UKSA, Oxford Space Systems and others.

SGL Carbon SE: Impairment in the Carbon Fibers business unit

With the publication of the half-yearly figures for 2024, SGL Carbon already announced that the company expects to achieve its adjusted EBITDA guidance for fiscal year 2024 at the lower end of the range of €160 to 170 million. Based on the preliminary figures for the first nine months of the fiscal year 2024, SGL Carbon confirms this statement.

With the publication of the half-yearly figures for 2024, SGL Carbon already announced that the company expects to achieve its adjusted EBITDA guidance for fiscal year 2024 at the lower end of the range of €160 to 170 million. Based on the preliminary figures for the first nine months of the fiscal year 2024, SGL Carbon confirms this statement.

According to preliminary figures, Group sales of SGL Carbon for the first nine months of fiscal year 2024 decreased by 4.8% year on year to €781.9 million (9M 2023: €821.7 million). Preliminary adjusted EBITDA, on the other hand, remained at a comparable level to the prior-year period, at €127.6 million (9M 2023: €130.0 million). Despite the slight sales decline, the adjusted EBITDA margin improved to 16.3% after nine months in 2024 (9M 2023: 15.8%). The reasons for the improved adjusted EBITDA margin are, in particular, product mix effects in the Graphite Solutions and Process Technology business units. By contrast, the ongoing weakness in demand for carbon and textile fiber products in the Carbon Fibers business unit and the early termination of a customer contract at Composite Solutions weighed on the Group's sales and earnings development.

The business unit Carbon Fibers manufactures carbon and textile fibers for the wind and automotive industries as well as various industrial applications. As expected by the Company for the fiscal year 2024, demand for carbon fibers from the wind and automotive industries remains weak. In addition, there is increasing competitive and price pressure due to global overcapacity for both carbon fibers and textile fibers. The company does not expect demand to recover in the coming months and the realizable prices for these products will remain at a low level beyond 2025. Furthermore, SGL Carbon expects that the anticipated improvement in sales and earnings for the Carbon Fibers business unit will be delayed and is revising its existing medium-term planning for Carbon Fibers.

Due to the associated expected deviation an event-driven impairment test is currently being carried out. This indicates a non-cash impairment charge of €60–80 million, which will be recorded in the fourth quarter of 2024. The impairment relates exclusively to Carbon Fibers; the operating business of the other business units is not affected.

SGL Carbon's equity ratio after the impairment is approx. 40% (September 30, 2024: 43.3% according to preliminary figures).

The review of all strategic options for the Carbon Fibers business unit, which was announced by SGL Carbon on February 23, 2024, and has already begun, remains unaffected by the impairment and is currently continuing.

Joining forces are industry leaders Arkema (resin supplier), Owens Corning (glass fiber supplier), LM Wind Power (blade manufacturer), SUEZ (dismantling and waste processing), CANOE R&D center (recycling technology), and ENGIE (life cycle analysis).

Each company played a crucial role in the development of the closed-loop recycling process:

  • Arkema developed and validated the generation of recycled Elium® monomer through thermolysis, and, together with its subsidiary Bostik, an innovative adhesive for the blade assembly that is recycled together with Elium® paving the way for industrial-scale implementation.
  • Owens Corning successfully recovered glass fiber at pilot scale, enabling its reintroduction into the production process for their Sustaina® product line.
  • LM Wind Power manufactured two wind turbine blades with Arkema’s Elium® resin and Owens Corning’s Ultrablade® fabrics; one blade including a large structural element made with recycled Elium® resin.
  • SUEZ provided cutting and grinding expertise for processing the blades.
  • CANOE R&D center optimized recycling for production and carbon blade waste, additionally developing methods for repurposing waste streams through mechanical recycling.
  • ENGIE conducted a comprehensive life cycle analysis demonstrating the environmental benefits of closed-loop ZEBRA blades and validated their economic viability.

A Sustainable Future for Wind Energy
The ZEBRA project successfully recycled Elium® resin and Ultrablade® fabrics from wind turbine blades and manufacturing waste, reformulating them back into usable materials. This closed-loop process addresses the growing challenge of end-of-life blade management within the wind energy industry.

  • Recycled Elium® Monomer: Arkema achieved a yield of over 75% in the thermolysis process, paving the way for industrial-scale production of recycled resin.
  • Recovered Glass Fiber: Owens Corning successfully retrieved glass fiber for remelting and reintegration into their Sustaina® product line.
  • Life Cycle and Cost Analysis: ENGIE's study confirmed the significant environmental benefits and economic viability of ZEBRA blades when assuming a closed-loop recycling system from production to end-of-life.

ZEBRA blade using Elium® thermoplastic resin, Bostik’s highly compatible adhesive and Ultrablade® fabrics is bringing the best closed-loop recycling solution compared to traditional thermoset system. The operating cost and investments for recycling facility are significantly lowered. The CO2 emission linked to the recycling operations is reduced as well. All those results are making the closed-loop recycling solution of ZEBRA blades a viable option both on economic and environmental standpoints.

By demonstrating the feasibility of full wind turbine blade recycling, the ZEBRA project paves the way for a more sustainable future in the wind energy sector.
