Effect of Carbon Fiber in Dry Brake Formulations

Carbon fiber is known to contribute to a new generation of asbestos-free brake friction formulations. Carbon fiber's thermal properties make it a desirable component in applications where high temperatures are involved. It is not an exotic material, and is used commercially by major friction material producers. Carbon fiber is not known to be a hazard to human health or the environment under present conditions of manufacture and use. It is easily processed in dry brake formulations with equipment typically used in the friction industry. The present paper demonstrates how one unique type of carbon fiber can make significant improvements in durability and structural properties of dry brake formulations.
