The article provides an overview of the current practices and methods used in friction material testing, including the testing equipment, procedures, and evaluation criteria. The authors highlight the importance of selecting appropriate test methods based on the intended use of the friction material, as well as the need to consider the influence of various factors such as temperature, pressure, and speed on the material’s performance.
The article reviews various test methods used for friction materials, such as the dynamometer-based tests, the SAE J2522 procedure for testing disc brake pads, and the JASO C406 standard for motorcycle brake pads. The authors also discuss the importance of using test results to develop appropriate design and manufacturing specifications for friction materials.
The article concludes by emphasizing the importance of ongoing research and development in the field of friction material testing, particularly in areas such as durability testing, wear prediction, and material characterization. The authors suggest that continued advances in testing methods and equipment will ultimately lead to improved performance and reliability of friction materials in a range of applications.
