摘要
A test apparatus for measuring surface friction of a damping material such as brake pad insulator material includes a rotor configured to support the damping material for rotation therewith, an actuator pressurizable to apply axially-inward force to the damping material and a stator configured to support the actuator. A sensor determines the force applied to the actuator and a torque cell is axially aligned with the rotor for measuring torque of the rotor in relation to force applied to the damping material. The calculation of surface friction of the damping material is possible based on the measured load and torque. A method of measuring surface friction of a brake pad insulator material as well as a method using a brake dynamometer is also presented.
