Title:
WET FRICTION MATERIAL
Document Type and Number:
Japanese Patent JP2017171921
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a friction material for use in a wet clutch incorporated into a vehicle transmission or other lubricated powertrain component, which functions even at surface temperatures higher than 300-350°C.SOLUTION: A wet friction material 10 for use in a wet clutch includes a friction interfacing surface 12 for frictional engagement with an opposed surface in the presence of a lubricant. At least a portion of the friction interfacing surface 12 comprises fibrillated nanofibers 14, which define a nanofibrous web 20, and friction adjusting particles 16 held by the nanofibrous web 20. A cured resin 18 bonds the fibrillated nanofibers 14 and the friction adjusting particles 16 together to provide structural support for the friction material 10.SELECTED DRAWING: Figure 1
