Title: Hiroyuki Fujikawa: Innovator in Friction Materials
Introduction
Hiroyuki Fujikawa is a notable inventor based in Itami, Japan. He has made significant contributions to the field of friction materials, holding a total of 3 patents. His work focuses on enhancing the performance and durability of automotive components.
Latest Patents
Fujikawa's latest patents include a friction material designed for use with disk rotors or drums. This innovative material is primarily composed of an aluminum alloy reinforced by hard materials. It effectively suppresses scoring on the disk rotor or drum and maintains a consistent coefficient of friction even after exposure to heat. The composition includes an organic-fiber base, binder resin, friction-adjusting agents, fillers, inorganic powders, inorganic fibers, and metal powders with particle diameters ranging from 1 to 180 µm.
Another significant patent is a method for manufacturing disk brake pads. This method allows for the formation of a friction member that consists of a bonding layer with low porosity and a matrix layer with high porosity, eliminating the need for a pre-forming step. The process involves feeding a pelletized mixture of components and a non-pelletized material into a mold cavity. The compacted bonding layer prevents moisture infiltration, reducing rust development on the back plate and improving bonding strength.
