Proposal of standard specimen for investigating mechanical behavior of rubbers

Abstract

Rubber is widely utilized as industrial material using its unique material properties. Since the properties are controlled by recipe, mixing and curing of rubber, research and development are active based on polymer materials view point. However, from materials and mechanics view point, fundamental material properties should be measured for each rubber. This leads difficulty to shear investigated results between researchers. In order to promote materials and mechanics research for rubber, research society activity started to propose standard specimen for investigating and shearing mechanical behavior. After surveying standard of rubber materials, a standard Styrene-butadiene rubber specimen was proposed including recipe and production method. The first specimen is made and carried out uniaxial tensile test.
