MECHANICS OF VISCOELASTIC COMPOSITES.

Abstract

Apparatus has been developed to measure the dynamic mechanical properties of foamed materials filled with a viscous fluid, over a frequency range from 0.002 to 200 Hz and a temperature range from -50 o C to +100 o C. Measurements have been made on various foam/ fluid systems including rubber latex, polyether and polyester foams filled with air, glycerin, silicone oil and water. The Gent-Rusch theory has been modified to take into account inertia effects, damping in the matrix material itself, and special features of the text-piece assembly . The theory is shown to describe the measurements successfully and verifies the engineering validity of the approach outline. (Author-PL)
