This document describes a compressive vibration, non-resonance method for determining the components of the compressive complex modulus E* of polymers at frequencies typically in the range 0,01Hz to 100Hz. The method is applicable for measuring dynamic storage moduli of semi-rigid polymers in the range 1MPa to 1GPa.
This method is particularly suited to the measurements of dynamic moduli and loss factors of semirigid plastics in the shape of a right-angled prism, cylinder or tube and can be conveniently used to study the variation of dynamic properties with temperature and frequency through most of the glassrubber relaxation region (seeISO6721-1).
