Abstract
A new method for measurement of dynamic flexile mechanical properties was developed by a modification of the Rheovibron viscoelastometer. The Rheovibron instrument is useful for obtaining dynamic tensile mechanical properties of films and fibers over a wide temperature range. A new flexile grip and procedure were used for measuring dynamic mechanical properties of material in the flexile mode using the Rheovibron instrument. The dynamic flexile properties on polyester, nylon 66, and acrylic fiber are presented.
