- the disk pads A to C using the KT LO of the present invention have a lower wear rate at a disk temperature of 30 ° C or more than the disk pads D and E, and have a lower wear resistance. It turns out that it is excellent. In addition, the coefficient of friction is relatively stable against temperature changes. Industrial applicability
- the friction material of the present invention has a very stable friction and wear characteristic from a low temperature to a high temperature range by including the levitoku site-type lithium potassium titanate of the present invention as a friction modifier, and can be used for a long time. Also, a friction material having stable friction and wear characteristics can be obtained.
