In this work, the effects of blend composition composed of 0, 10, 20, 30, and 40 wt.% of nylon6 to epoxy resin were investigated in terms of cure kinetics and thermal stability by DSC and TGA. As the content of the nylon6 increased, the maximum exothermic temperature (Tm) and the value of cure activation energy (Ea) were decreased. Nylon-dispersed-phase interferes with the exothermic reaction of the epoxy, and affects on the decrease in the reaction temperature. From TGA analysis results of the DGEBA / nylon6, the thermal stability based on the thermal stability index (A*·K*) and integral procedure decomposition temperature (IPDT) were increased with increase in the nylon6 content. This was because of the combination of the DGEBA and nylon6 having good heat resistace, resulting in improving thermal stability of the DGEBA/nylon6. |
