MECHANICAL PROPERTIES OF HIGHLY FILLED ELASTOMERS V
Abstract
About 60 polyurethane - sodium chloride composites were prepared. The content for materials filled with single fractions ranged from 0 to 55% by volume; the size of these fractions from 1 to 300 micrometers. Materials with a content of 50 to 70% by volume were made by using a mixture of a coarse and a fine fraction. For these materials, primary tensile creep and rupture properties, both at various constantly high stress levels, were determined at room temperature. Further recovery after primary creep was investigated. The filled rubbers showed a typical tensile creep behaviour, related to the growth of vacuoles in the material (de-wetting). Generally, the processes of de- wetting, recovery and rupture were considerably delayed by a decrease in particle size (reinforcement). The effect of de-wetting on creep, much depended on the content of filler.
