  • Dual-layered graphene-based wet friction material
    Patent number: 12504051
    Abstract: A dual-layered graphene-based friction material is a paper matrix that is used as a high friction engagement lining in applications such as clutch plate or wet brake plate linings. The material uses a porous yet elastic fibrous base layer and a top layer containing thermally conductive graphene nanoplatelets mixed with a thermosetting resin. The top layer increases the overall thermal capacity while maintaining sufficient material porosity that allows satisfactory cooling oil flow through the material.
