Thermal and Dynamic Investigations on Brake Pad Composites Produced with Lignin-Phenol-Formaldehyde Resin

Abstract:

Brake pads are composite materials which have been constantly improved by new materials that increase the quality and reduce the non-renewable raw materials. The goal of this work is to study the behavior of brake pads produced with replacement of phenol-formaldehyde resin by lignin up to 40% weight ratio. The Krauss method of characterization and SEM analysis were employed. The results showed an average friction coefficient approximately to μ_m=0.4 and a heterogeneous surface morphology. The satisfactory results are compatible with the current friction materials.
