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 consumption. The goal of this work is to study the behavior
of brake pads produced with replacement of phenol-formaldehyde synthetic resin by lignin, a by-product provided
from the paper industry, up to 40% weight ratio. It was employed standard methods (Krauss method) of
characterization, dynamic-mechanical analysis, and scanning electron microscopy. The resultant material showed
an average friction coefficient (µ m ) approximately to 0.4, low level of wear, and good interaction between fibers
and the polymeric matrix. The satisfactory results are compatible with the current friction materials.
