Quality Assurance Strategy in Light of Continuously Changing Properties of Disc Pads and Discs Panel Discussion

Panelists - Joe Betoski, Business Development, Woodworth Inc. Pietro Durando, North America Friction R&D Manager, ITT Friction Technologies Charles (Chip) Evans, Specialist, Ford Motor Company Peter Kula, Application Integ Engineering, ZF Meechai Sriwiboon, R&D Director, Compact International (1994) Co., Ltd. Brake discs and brake pads tend to change their physical properties over time, either during storage or during brake testing. These changes are caused by internal residual stress relief in the case of discs, and by internal residual stress relief/cross linking of the resin in the case of pads, in addition to dimensional changes. This causes needs for revised quality assurance strategies. Panel participants will present their suggestions and discussed future directions for your consideration.
