Abstract
In this work, effects of the blend composition composed of 0, 10, 20, 30 and 40 wt% of nylon 6 to epoxy (diglycidylether of bisphenol-A, DGEBA) resin were investigated in terms of cure kinetics and thermal stability by differential scanning calorimeter (DSC) and thermogravimetric analysis (TGA). As the content of the nylon 6 increased, the maximum exothermic temperature ($T_{max}$) and the value of cure activation energy ($E_a$) decreased. The maximum exothermic temperature of the blending samples decreased with increasing in nylon 6 content, resulting in the decrease in curing activation energy of them due to the rapid curing reaction with epoxy resin in this system. From TGA analysis results of the DGEBA/nylon 6, the thermal stability based on the thermal stability index ($A^*{\cdot}K^*$) and integral procedure decomposition temperature (IPDT) increased with increase in the nylon 6 content. This was because of the combination of DGEBA and nylon 6 having good heat resistance, resulting in improving thermal stability of the DGEBA/nylon 6.
