COBRA will demonstrate a completely novel brake pad production technology that will be based on an innovative hydraulic binder composition instead of phenolic resins, at comparable braking performance.
State-of-the-art brake pads are constituted by thermosetting phenolic resins, which are suitable for friction and relatively high contact temperature applications. Moreover reinforcing and filling constituents (about 90% in mass) are incorporated into the polymeric matrix.
Raw materials involved in the innovative hydraulic binder production will allow reducing energy consumption (75-83 MJ/kg phenolic resin compared to 3-9.4 MJ/kg cement) and water consumption (94-282 L/kg phenolic resin compared to 1.7-5.1 L/kg cement).
In addition the novel technology will avoid the emission of aerosols and secondary ultrafine particulate (PM0.1 in particular) generated during braking by traditional phenolic-resin-made pads.
