- Best mechanical properties
- Low density (light weight)
- Good electrical conductivity
- Excellent impregnation behavior
- Good spreadability
For high-tech applications requiring high strength and stiffness combined with light weight, SIGRAFIL continuous carbon fiber tows are indispensable. They form the basis for high-performance composite materials such as textiles and prepregs, as well as components made of carbon fiber-reinforced plastic (CFRP). Carbon fibers are used in the automotive industry, in aerospace, in wind turbines, but also in sports equipment or mechanical engineering.
