Abstract
An improved apparatus and process are described for measuring linear and non-linear viscoelastic properties of viscoelastic materials such as nylon, polyester tire cord, rubber, rubber-tire cord composites and the like. The properties are determined by subjecting a sample material to a constant-rate strain displacement having a small amplitude high frequency sinusoidal strain displacement superimposed thereon, and analyzing the overall resulting material stress. The obtained properties can be used to predict and estimate actual end use characteristics of the material such as longevity and mechanical loss during performance. In the case of tire cord, this latter characteristic can be surprisingly related to efficiency of fuel consumption in automotive vehicles.
