Viscoelastic and Thermomechanical Behavior of Hysol 141A Resin

Abstract

Hysol 141A resin (an experimental epoxy resin for filament wind-ing purposes) was investigated for its viscoelastic and thermome-chanical behavior. The creep behavior of this resin increases strongly at slightly elevated temperature, which gives rise to some concern if this material were exposed to longterm loading. The resin modulus decreases rapidly above room temperature and the resin is virtually a rubber above 100^C, which makes the use of Hysol 141A highly questionable as a winding resin for rocket motor chambers. This report describes the results of using the time-temperature superposition principle to estimate the long-term creep behavior of an experimental epoxy resin (Hysol 141A) DESIGNED FOR FILAMENT WINDING OF ROCKET MOTOR CHAMBERS. Also de-termined was the change of resin modulus as function of temper-ature. The intent of the investigation was to obtain pertinent resin properties of this candidate resin for possible use in the TRIDENT rocket motor chambers, since the production of ERLA 2256 (the best resin presently used for this purpose) has been discontinued.
