Sintered composite friction material comprising fluorocarbon resin
Abstract:
A sintered fluorocarbon resin based composite friction material having a high coefficient of friction, greater hardness, good machineability and improved wear resistance. The composite material comprises a homogeneous blend of fluorocarbon resin, aramid and carbon fibers, aluminum oxide and polyester compound. Also provided are process steps required to produce such materials with the desired characteristics of homogeneity, hardness and wear resistance. These steps include a premix together of the fiber components and final sintering at a pressure of about 1600 psi.
