These materials, which address the need to reduce costs and CO2 emissions, and improve the production process and fuel efficiency of next-generation commercial aircraft, will be based on SGL Carbon’s large-tow IM carbon fiber and Solvay’s primary structure resin systems.

The agreement encompasses both thermoset and thermoplastic composite technologies. It builds on Solvay’s leadership in supplying advanced materials to the aerospace industry and SGL Carbon’s expertise in high-volume carbon fiber manufacturing.

Augusto Di Donfrancesco, member of Solvay’s executive committee said:

“For Solvay, this is an opportunity to lead the aerospace adoption of a composite material based on 50K IM carbon fiber. This is a highly competitive value proposition that brings more affordable high-performance solutions to our customers. We see this as the first step in a long-term partnership.”

Dr. Michael Majerus, spokesman of the management board of SGL Carbon said:

“By combining SGL’s carbon fiber expertise in our newly developed, unique 50K IM fiber with Solvay’s resin formulation and aerospace market expertise, both partners are aiming to develop an advanced aerospace material system. This alliance supports our strategic direction and accelerates our growth in the attractive aerospace market.”

Composite materials for aerospace applications represent a multi-billion-dollar market that is expected to grow strongly in the coming decade. Solvay and SGL Carbon are positioned to develop solutions to address the needs of this market.
