ELASTIC AND VISCOELASTIC PROPERTIES OF SYNTHETIC RUBBER (POLYCHLOROPRENE): DYNAMIC AND STATIC CHARACTERIZATION

摘要

The evaluation of macroscopic elastic and viscoelastic properties of rubber-like polymer materials may be carried out experimentally by using accurate static and dynamic measurement techniques. However, the viscoelastic behavior of rubber-like polymeric materials involves different elastic and damping responses, as a function of particular mechanical stress applied during an experimental test. In this work experimental results of the elastic modulus and damping coefficients measured with static and dynamic methods are compared. The measurement techniques, performed in controlled temperature conditions, and the experimental data are accurately described.
