SIGRASIC products derive their extraordinary properties from carbon fiber-reinforced silicon carbide (C/SiC) - a composite material that combines carbon fibers within a ceramic matrix to maximize the properties of both materials.
The benefits of SIGRASIC are:

Application examples for SIGRASIC®: NASA sensor carrier designed for low weight, high precision and high stiffness; pump impeller for highly corrosive and abrasive media; (high performance) clutch disk mass produced for cars/vehicles with excellent wear and strength properties; ballistic protection with complex shaped designs and high hardness.
Technical properties are customizable for individual purposes, base materials can be designed with the relevant content and type of carbon fibers.
C/SiC is manufactured by infiltrating a carbon fiber-reinforced carbon body with silicon. Due to near net shape processing, complex machining can be performed cost-effectively early in the process. Final ceramic grinding can be used locally when tight tolerances are required. By suitable adjustment of the material and process parameters, the product characteristics can be matched to the intended use of the SIGRASIC component.
