SIGRABOND® Carbon Fiber-Reinforced Carbon

Lightweight, high-strength, reliable.

Carbon fiber-reinforced carbon (C/C, CFRC) is a high-strength composite, that consists of a carbon or graphite matrix, that is fortified with very strong carbon fibers.

There is a wide variety of carbon composite material types. The material is mainly used highly demanding high temperature applications.

We market our C/C products under the SIGRABOND brand.

Light (perfect for automation tasks)
Very strong at highest temperatures
Highly fracture resistance
High thermal shock resistance
Low thermal expansion

Out product portfolio offers a wide variety of carbon composite products, that we also like to combine to provide optimum compatibility to customer processes:

SIGRABOND Standard for heating elements and furnace linings
SIGRABOND Premium for heating elements and highly stressed parts
SIGRABOND Performance for charging racks and systems
SIGRABOND Filwound for cylindrical parts
SIGRABOND Mechanical for fasteners
SIGRABOND Heatshield for heat shields in high temperature furnaces
SIGRABOND Sinter for high temperature applications, especially for sintering processes

Carbon fibers and resins are the raw materials needed to manufacture C/C materials. Molding is accomplished through processes such as lamination or winding followed by pressing and curing of the pieces. The carbonization and graphitization steps are part of the thermal manufacturing process. In the final treatment phase, the work pieces are machined to the desired dimensions through mechanical processing.
