Latest Patents

Hara holds a patent for a friction material and method for manufacturing the same. This invention utilizes a friction material composition that includes a fiber, a friction adjusting material, a binding material, and an uncrosslinked rubber that is solid at normal temperature (25°C). The resulting friction material exhibits an ambient compressibility of 2% or less at normal temperature (25°C) and at 4 MPa. Additionally, it maintains a tan δ value in the sliding direction at temperatures ranging from -20°C to 50°C of 0.05 or larger. This innovation provides high damping properties, acceptable brake noise, and prevents a decrease in responsiveness when brakes are applied. It also addresses issues related to fuel efficiency and abrasion caused by contact with brake rotors.
