Sizing types of our SIGRAFIL® continuous carbon fiber tows
By applying different types of sizing, the carbon fibers can be optimally matched to different matrix systems. In this way, it is possible to produce application-tailored versions as well as the standard materials. So, together with our customers, we find optimized solutions for their challenges.
