METHOD FOR EVALUATING MIXED STATE OF STIRRED FRICTION MATERIAL

摘要

PROBLEM TO BE SOLVED: To obtain a friction material having stable quality and performances by quantitatively evaluating a mixed state of the stirred material of friction material for a brake. SOLUTION: This method for evaluating the mixed state of the stirred friction material is characterized by quantitatively evaluating the mixed state of the stirred material of friction material by discriminating between the objective material of evaluation of the friction material and nonobjective materials thereof and dividing the materials into two values with using an image analysis device and quantitatively measuring a size, an amount and a dispersed state of the objective material of evaluation.
