DYNAMIC MECHANICAL BEHAVIOR OF A COMPOSITE VISCOELASTIC MATERIAL.
Abstract
An investigation was made into the dynamic mechanical bheavior of a soft binder material (Solithane 113), which had dispersed in it a number of small aluminum particles. By varying the volume fraction concentration of the filler material, the effect of the filler concentration on the dynamic characteristics was determined. A theory was developed which considered the dynamic behavior of the composite material as a function of the moduli, and volume fraction of each constituent material. This theory was then used to predict the materials dynamic properties for filler concentrations, and frequencies studied in the experimental investigation. The theoretically predicted moduli values were compared with the experimental results showed that for low filler concentrations and at low frequencies the correlation between theory and experiment was good. At high frequencies and filler concentrations the correlation was found to be poor.
