Temperature Dependent Mechanical Properties of Natural and Synthetic Rubber in Practical Structures

In this proposal the mechanical properties of natural and synthetic rubbers are studied under different temperatures both real ageing heat treatment conditions. For purpose, tire rubber bearing pad considered as they most governed in respectively. The experimental results confirm that impact temperature is higher on than because ambient aggravate thermal motion changes molecular arrangement other samples recovers during breezy. Except hardness, all cases terms like tensile strength, elongation, Young's modulus Poisson's ratio provide performance rubber. Under condition degraded recover well by since extremely ordered long chain structure. significant differences micrographs two suggest consists uniform grains its highly controlled arrangement. microstructure turned rougher size voids became larger increases secondary cross linking reaction which initiate to cracks.
