Abstract

Effect of CNSL addition as a friction modifier on the wear characteristics and mechanical properties of non-asbestos composites brake pad was investigated. For this purpose, the content of CNSL in the matrix structure was only changed in the range of 0 - 5 wt.% and six different compositions were prepared. Only the amount of resin were changed, other ingredients in the mixture were keept constant. The brake-pad samples were tested for their friction and wear behavior on a pin-on-disk type test configuration according to the NF F 11-292 French standard. It was observed that coefficient of friction of composite decreased with increasing CNSL contents up to 2wt % level, above which coefficient of friction increased. Specific wear rate however, linearly decreased with increasing the amount of CNSL content in the matrix. On the other hand, CNSL addition to the composite matrix decreased the some mechanical properties such as hadness, compressive strength and elastic module of sample, while increased the compressibility values.
