The curing reactions of the epoxy resin 2,7-bis(4-N,N-diglycidyl amino phenoxy) naphthalene using diamino diphenyl sulfone (DDS), diamino diphenyl methane (DDM), triethylene tetra amine (TETA) and diethylene triamine (DETA) as curing agents were studied kinetically by differential scanning calorimetry. The dynamic scans in the temperature range (20-300°C) were analyzed to estimate the activation energy and the order of reaction for the curing process using some empirical relations. The activation energy for the various epoxy system is observed in the range 67.4-121.5 KJmol-1. The cured epoxy resins were studied for kinetics of thermal degradation by thermogravimetry in a static air atmosphere at a heating rate of 10°Cmin-1. The thermal degradation reactions were found to proceed in a single step having an activation energy in the range 41.84-71.84 KJmol-1. The data were utilized in fabricating the glass-fibre reinforced epoxy composites. Glass fibre reinforced composites were fabricated using the matrix resin DGEBA and the above tetrafunctional epoxy resin in the ratio 80:20 using different curing agents and evaluated for their physical, mechanical, chemical and electrical properties. |
