Abstract
Recently high heat resistant friction materials containing synthetic fibers have been developed to meet the requirements from heavy-duty vehicle manufactures. However, traditional cut in groove process (hereafter, CIG process) cannot cut grooves on these materials clearly. Projection near groove and fuzz inside of groove exist after the CIG process. The projection and fuzz are generally considered the reason of high drag torque during idling [1]. But very little information was provided to deal with the projection and fuzz and how to reduce the drag torque caused by projection and fuzz.
In this paper, various processes will be discussed to reduce drag torque and an optimized groove specification will also be proposed for high heat resistant friction materials for heavy-duty vehicles.
