SGL Carbon and Solvay have entered into a joint development agreement (JDA) to bring to market the first composite materials based on large-tow intermediate modulus (IM) carbon fiber. 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.
