Abstract :
The present study was aimed to assess the effect of replacing copper in the brake pad with potassium titanate platelet (PTP) and ceramic fiber (CF). Chase dynamometer tests were conducted to compare a brake pad s tribological behavior when PTP and CF are added to the composition with that of the copper-bearing pad. The results indicated that PTP and CF demonstrated promising outcomes such as a stable coefficient of friction (COF), lower wear rate, and better heat resistance in copper-free friction composite. Scanning electron microscope (SEM/EDS) analysis was conducted to investigate the role of main elements such as Ti, Fe, K, O, and C on the formation of contact plateaus of friction composites. PTP maintained both continuous contact and smooth friction braking application of a brake pad. The uniform distribution of Ti on the wear track on the worn surface depicts the role of PTP in stabilizing the friction film formation.
