Cure Kinetic Behavior of 191# Unsaturated Polyester Resin Used in Advanced Composites

Article Preview

Abstract:

The cure kinetic properties of 191# resin was studied by means of the differential scanning calorimeter (DSC) data. Dynamic DSC scanning at four different heating rates (5, 10, 15 and 20/min) are employed to investigate the cure kinetics. DSC curves show that there are two exothermal peaks. Kissinger’s method is applied to processing the data. The activation energy E and pre-exponential factor A were gained by linear regress and the cure kinetics model was developed. Based on T − β method, the temperatures of cure reaction beginning, maximum reaction rate and reaction ending were obtained. These will help to process designing of unsaturated polyester resin used in advanced composite materials.
