Abstract: In this study ortho and meta cresol novalac epoxy resins were synthesized to study their mechanical and tribological behaviour under dry sliding conditions. The friction and wear tests were carried out on a pin on disc apparatus under applied normal load of 10, 20, 30 and 40 N and different sliding velocity of 0.9, 1.8, 2.7 and 3.6 m/s respectively. To evaluate mechanical properties of these synthesized novalac epoxy resins the tensile, flexural and compression tests have been carried out. It is found that in both novalac epoxies the coefficient of friction decreases with increase in the applied normal load and increases with increase in the sliding velocity where as specific wear rate increases with increase in the applied normal load and decreases with increase in the sliding velocity. It is also found that the mechanical properties of the ortho cresol novalac epoxy resins showed better results in comparison to the meta cresol novalac epoxy. The morphology of these novalac epoxy is studied with the help of (SEM) scanning electron microscope.
