| Abstract | Brake pad is a product that plays a role in the automotive parts industry as a consumable, and directly affects trafficsafety. The objectives of this study were to address the problems with brake noise, vibration, and harshness (NVH) from brakepads, by using a reinforcement material layer, and to raise the quality of brake pads used in the industrial sector. As a result,prototype brake pads with reinforcement by a damping layer were prepared and tested. The experiments revealed that brake padswith damping layer can reduce vibration and also brake noise at a given frequency by at least 10 percent when braking at speedsof 50, 100 and 130 km/h. Besides, this technique can be applied to the production of brake pads as demonstrated. However, theprototype brake pads are still in product development phase for testing in a variety of conditions, as regards both temperaturefactors and the usage period. |
