Carbon: the super light material Carbon fiber reinforced plastic, also known as carbon fiber reinforced plastic (CFRP), also shortens carbon fiber, carbon or carbon, is a composite material in which carbon fibers are embedded in a plastic matrix. The matrix serves to connect the fibers and to fill the spaces between them. The material epoxy resin is usually chosen as the matrix. Carbon is only heat-resistant to a limited extent. Speed Products has therefore developed thermal insulation that protects the carbon from the inside against the hot exhaust gases. We have christened this proprietary development RI Carbon: Reinforced Carbon. However, for reasons of durability and of course considerable weight advantages, carbon is only recommended for racing. For a durable use in normal road traffic there are better materials, such as the stainless steel( 0,7mm) developed by Speed Products, which is also very light.
