MECHANICAL PROPERTIES OF HIGHLY FILLED ELASTOMERS VI. INFLUENCE OF FILLER CONTENT AND TEMPERATURE ON ULTIMATE TENSILE PROPERTIES

Abstract

Results are presented of stress-strain tests performed at various temperatures and strain rates on materials filled with various amounts of sodium chloride particles with a mean size of 0.1 mm. Stress and strain at rupture decreased with increasing filler content. For each material investigated it was possible to construct the well-known failure envelope by means of which the results could be described adequately. The dewetting of the particles in the rubbery matrix, sometimes resulting in a maximum in the stress-strain curve, is ascribed to failure of the rubber between the particles and not to failure of the rubber-salt bond, because the dewetting maximum was dependent on temperature and time in the same way as the rupture properties of the unfilled material. The results are compared with earlier investigations, e.g. high speed tensile tests and creep experiments, and a good agreement is found.
