This article deals with the mixtures of two different synthetic rubbers consisting of SBR and NBR with novolac type PH, which can be used as organic binder of the composite friction materials particularly for railroad brakes.
Special attention is given to acquire further understanding concerning the influence of the constituents of the blend including the rubber vulcanizing ingredients and the resin content.
To reduce the size of experiments, Taguchi’s experimental design method is utilized to investigate the compositional parameters of the blends.
The morphological characteristics of the blend are also examined by using dynamic and static mechanical analysis
and scanning electron microscopy (SEM).
