50, SIGRAFIL® continuous carbon fiber tows The basis for high-performance composites We focus on what keeps our customers one step ahead. Continuous carbon fiber tows are heavy tows with 50 000 filaments (50k). Each of our 50k heavy tows have outstanding mechanical properties that can be transferred to the finished products and components. The fibers can be chosen to match specific requirements, for example by prioritizing stiffness or strength. In addition, these wide 50k fiber tows offer time and cost advantages, especially in high-volume processes. Smart solutions from SGL Carbon – the...
