Development of a Composite Friction Material with Excellent Fade Resistance by Employing Oversized Ceramic Particles

Non-asbestos organic friction materials have historically been developed through a series of trial-and-error experimental procedure. But in this work, the friction theory was used to design and prepare a new composite friction material with excellent fade resistance. Oversized (3.0 ± 0.5 mm) SiO 2 -based particles with the great thermal stability and large contact area against the disc were used to reinforce the resin matrix. The effectiveness of the oversized particles relative to particles of other sizes was evaluated using an established test procedure. The results showed that the oversized particles improve the fade resistance and wear resistance of materials, but not followed with excessive disc wear.
