| Abstract: | The curing characteristics of the vinyl ester resins with different curing agent formulations were studied by differential scanning calorimetry (DSC). The relationships among the exothermic capacity in the curing process, degree of curing and the mechanical properties of castings were investigated, and the mechanical performance of the molded and pultruted composites were evaluated. It is found that the range of curing temperature for vinyl ester resins becomes narrowed and the exothermic capacity is increased by using mixed curing agents. The exothermic capacity could reflect the degree of curing and directly affect the mechanical properties of castings and composites. |
