COMPENDIUM OF MEASURED RHEO-OPTICAL PROPERTIES OF HYSOL 4485

Abstract

A measuring program was conducted with the aim of determining the complete rheo-optical characterization of a certain urethane rubber compound (HYSOL 4485) suitable for dynamic photo-visco-elastic studies. The shift curve and the master curve at 60F are presented for both the Shear Storage Modulus and the Shear Loss Tangent. In determining the shear properties sinusoidal loading of specimens cut as hollow cylinders was used. Using a method designed originally by Selway and Brown the dynamic stress optic coefficient and the complex Youngs Modulus were measured at room temperature. The following tests were conducted in an atmosphere maintained at 70F and 40% R.H. Youngs Modulus in creep was measured at two stress levels: 20.0 and 41.7 p.s.i. Dynamic stress-strain curves were determined using Volterra pendulum tests at two initial velocities 7.02 and 65.5 inches per second; and the static and dynamic stress optic coefficients were measured.
