Thermal investigations of curing process of EPYŽ epoxy system

M. Urbaniak K. Grudziński

Abstract

The curing, postcuring and additional postcuring of the EPYŽ epoxy system (applied for ship machine foundation chocks) have been examined by differential scanning calorimetry (DSC) and dynamic mechanical thermal analysis (DMTA). Parameters of curing have been determined by a dynamic variant of DSC at various heating rates. DMTA method has given an information on the epoxy system viscoelasticity. The crosslinking degree was calculated from the heat of the dynamic curing reaction. The influence of heating rate on curing parameters was shown. Glass transition temperatures of the postcured and additionally postcured epoxy systems was also determined. The results showed that the temperature range of softening of machine foundation chocks could be shifted beyond the range of their operating temperatures.
