STUDY ON HIGH TEMPERATURE CURING EPOXY RESIN SYSTEM MOULDING BY VARI

Abstract

Abstract: A high temperature cured epoxy resin system (5284VARI) moulding by VARI was designed. Curing reaction characteristics of this epoxy resin were tested by DSC (Differential Scanning Calorimeter). The operation characteristics of this epoxy resin system were analysed by rheometer. The mechanical properties of this resin system and its composite were tested by mechanical testing machine. The results demonstrated that 5284VARI epoxy resin system has low viscosity on moulding temperature and can maintain long duration. This resin system is appropriate for moulding composites by VARI. Besides, this epoxy resin has good properties under wet-and-hot conditions.

Key words: epoxy resin, VARI moulding, composite, high temperaturecomposites, bismaleimide resin, prepreg, pressure applying moment, mechanical properties
