- Summary:
- Friction stability and wear resistance are key factors in brakesystem design and performance. The paper deals with theexperimental investigation of friction characteristics and wear ofthree commercially available NAO (non-asbestos organic) disc brakefriction materials viz. Grade A, Grade B and Grade C for a sportutility vehicle. The composites were evaluated for various frictionperformance properties such as average coefficient of friction,performance at various speeds (8.34 m/s to 38.89 m/s) and pressures(2 MPa to 12 MPa), fade and recovery behavior. These friction andwear characteristics were determined using four wheeler inertiadynamometer. The physical properties such as density, hardness,heat swell, water swell, adhesive bond strength at room temperatureand adhesive bond strength at 400°C were studied according toIndian Standards. In addition SEM-EDX (Scanning electron microscopewith energy dispersive X-ray) analysis was carried out for findingingredients and micro structural characterization of brake frictionmaterial. Finally the results are discussed and correlated to theobserved friction phenomenon. The coefficient of friction was foundto be highest for Grade B and lowest for Grade A and wear of GradeA was lower than that of grades B and C. It was observed that thecoefficient of friction increases with increase in speed from 8.34m/s to 22.23 m/s and then it continuously decreases for speed up to38.89 m/s. The maximum coefficient of friction was observed at aspeed of 22.23 m/s for all the grades viz. A, B and C.
