Abstract:
The objective of this research is to study the effect of mixed phenolic resin properties on the physical, mechanical and thermal properties of brake pads. Phenolic resins used in this study were resin A and resin B, the different ratios of which were 100:0, 75:25, 50:25, 25:75 and 0:100. The results showed that the increase in resin B content in mixed phenolic resin resulted in greater flow distance. The flow distance of different mixed phenolic resins did not affect the apparent specific gravity, degradation temperature, friction coefficient and wear rate but they affected the porosity, hardness, Youngs modulus, shear strength, and toughness of brake pads. In this study, the mixed phenolic resin with resin A to resin B of 25:75 (sample R4) gave the superior mechanical properties to the current phenolic resin (sample R1). Moreover, the use of R4 brake pad can save the production cost of 90,750 THB per year.
