Generalized braking characteristics of friction pad synthetic graphite composites

Present paper discusses frictional sliding response and stability of graphite-based composite brake pad material under ranges of pressures (P), sliding velocities (V) and material properties (graphite particle size, hardness, ultimate tensile and flexural strengths) of (2–4 MPa), (11.4–15 m/s), (20–470 μm), (70–90 HRL), (6–16 MPa) and (5–37 MPa), respectively. One generalized equation is derived to express this response. Optimum μ of 0.485 is attained at values of P, V and material properties of 2 MPa, 15 m/s, 21 μm, 90 HRL, 15.84 and 6.85 MPa, respectively.
