Carbon Fibers Using Drum-Filters

Abstract

Carbon fibers are the basis for one of the most promising construction materials to achieve high stability and light weight. The capabilities are manifold in all kind of industry [1]. Products including carbon have reached meanwhile series production and recycling of carbon products started. The whole life cycle from production of fibers, production and usage of carbon products to the recycling during different production stages and at the end of the product life of carbon fiber products is meanwhile available. Recycling of carbon is ecological and economical especially due to the high energy cost during the production stages. During the production of carbon fiber filaments, rovings, fabrics, prepregs or products carbon dust can be generated. Typical diameter of single carbon fibers are in 5…9 µm, typical rovings consisting of several thousands of fibers. In the next step fabrics and prepregs are manufactured. Carbon dust is generated during the textile processes and later on by grinding, milling or cutting results the products. The electrical conductivity of carbon can be useful or harmful [2]. Carbon dust can result e.g. in complete damage of electric components due to short-circuit or hygienic impacts. Suction and ventilation the complete production processes are therefore necessary.
