JEC Group have brought together the international community of composites leaders and executives in our Composites Circle as an unique networking opportunity to meet with both peers and future partners.
SGL Group, The Carbon Company, 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. This material, which is marketed under the trade name SIGRABOND® Performance, has special properties compared to other CFRC materials on the market. For example, it is 20% stiffer and can be processed to create intricate structures, with the material being ideal for technically demanding high-temperature applications.Rüdiger Mackenthun, head of the graphite specialties business unit stated: “This new carbon fiber reinforced graphite material is an exceptional example of SGL Group’s development expertise. The enhanced product properties offered by SIGRABOND® Performance are a major advantage for our customers. SIGRABOND® Performance represents a new addition to graphite specialties’ broad product range. Our customers benefit from an impressive, single source solution to all their needs in the area of hightemperature-resistant materials.”Carbon fiber reinforced graphite materials are ideal for use in high-temperature processes requiring lightweight 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”.SIGRABOND® Performance was developed by SGL Group. Thanks to its new type of structure based on unidirectional rather than conventional woven carbon fiber fabrics, the product offers dramatically improved performance and can be optimized to meet individual customer requirements. With this product, SGL Group offers a solution that enables its customers to create material saving structures.
