Sigrafil C T50-4.8/280 carbon fiber meets high mechanical requirements due to its high stiffness and strength.

SGL Group has introduced a carbon fiber with a high Young’s modulus, making it suitable for aerospace applications. Sigrafil C T50-4.8/280 can also be used to make pressure vessels, drive shafts, profiles, and sheet molding compounds (SMCs), as the fiber meets high mechanical requirements due to its high stiffness and strength.

The high Young’s modulus based on a 50k fiber (50,000 individual filaments) is unique to the market, SGL claims. Previously, only fibers with lower numbers of filaments (e.g. 12k or 24k) achieved these high mechanical properties (4,800 MPa, 280 GPa).

‘With the new Sigrafil 50k carbon fiber, we can now offer aerospace industry customers attractive material solutions for various component classes,’ said Andreas Erber, head of the aerospace segment at SGL Group.
