SGL Group – The Carbon Company (Wiesbaden, Germany) says it has developed a new type of carbon fiber-reinforced graphite material designed for industrial heat treatment applications. The product is carbon fiber -reinforced carbon (CFRC), a high-strength composite comprising a graphite matrix and reinforcing fibers made of carbon. The material, which is marketed under the trade name SIGRABOND Performance, is said to have special properties compared to other CFRC materials on the market. For example, it is 20 percent stiffer and can be processed to create intricate structures, particularly in technically demanding high-temperature applications.

Carbon fiber reinforced graphite materials reportedly are ideal for use in high-temperature processes that require light weight and temperature-resistant materials such as the heat treatment of steel components for the automotive and aerospace industry, or the coating of silicon wafers in the photovoltaic industry. A current application example from the automotive industry is the fully automatic heat treatment of transmission components on charging fixtures.

Carbon fiber in material is unidirectional rather than conventional woven carbon fiber fabrics, which is said to improve performance and can be optimized to meet ´┐╝individual customer requirements.
