Porous wet friction material utilizing a compliant epoxide resin binder system

Abstract

A wet friction material is disclosed bonded to a plate for transmission of motion, with the friction material made up of a porous fiber substrate, which is at least partially impregnated with a catalyzed resorcinol diglycidyl ether resin to improve friction properties.

What is claim d Is:  
     
         1 . A wet friction material comprising a base containing fibers, and a resin at least partially impregnating said base, said resin comprising at least 60 percent of a catalyzed resorcinol diglyoidyl ether.  
     
     
         2 . The wet friction material of  claim 1 , wherein the resin is diluted in a solvent prior to application to the base, and the solvent is evaporated.  
     
     
         3 . The wet friction material of  claim 1 , wherein the material is essentially thermosetting.  
     
     
         4 . The friction material of  claim 1 , wherein the base comprises cellulose fibers.  
     
     
         5 . The friction material of  claim 1 , wherein the friction material is essentially a flat disk, and a rigid flat plate adhered to the flat disk.
