Abstract:This paper focus on studying the effects of two different curing agents (tetrahydromeythyl-1,3-iso鄄
benzofurandione MeTHPA, and 4,4-diaminodiphenyl sulfone DDS) on curing reaction and curing properties of 1,1,2,
2-tetrakis(4-hydroxyphenyl)ethane tetraglycidyl ether(TGE). The curing behavior of the TGE was characterized by
scanning calorimetry analysis (DSC). The results demonstrated that curing reaction activating energy of two epoxy res鄄
in/ hardener systems were 65.8 kJ/ mol and 68.4 kJ/ mol, respectively. The curing resin thermal properties and mechan鄄
ical properties were investigated by dynamic mechanical analysis (DMA), thermal gravity analysis (TGA) and universal
testing machine, respecticaly. The glass transition temperature(Tg) of MeTHPA system is 188益. Tensile and flexural
strength is 33 MPa and 48 MPa. The Tg of DDS system is 203益. Tensile and flexural strength is 61 MPa and 93 MPa.
