Ageing-Time Dependence of Mechanical Properties of an Elastomeric Glass.

Abstract

Compressive stress-strain curves of two different glasses of a polyurethane based elastomer have been obtained at 3 Kbar and -5.5 C as a function of ageing time. The glasses were formed by two different perturbation jumps of pressure and temperature. The shape and the size of the curves depended on the path and ageing time. Young's modulus increased with ageing time and represents a good mechanical parameter for determining relaxation of polymer glasses. Keywords: High pressure; Elastomer; Solithane 113; Glass relaxation; Relaxation time; Modulus of elasticity.
