Abstract:
Some of the mechanical properties of polymer, such as tensile test, creep and swelling, were studied for two types of tire rubber at different concentrations of black carbon(70% ,30%) respectively. In the tensile test, the elasticity modulus was calculated and found that it was 7.836 MN/m^2.Also in the study of creep,the time-dependent creep modulus and the creep compliance were calculated.Then the swelling behavior was introduced using three chemical solutions, namely methane, acetone and benzene, and found that the rubber, which contains 30% of carbon has been degraded by methane but it was not affected by the rest of the other solutions. While the other type of rubber has been swelledin benzene and its mass increased significantly.
