Abstract
The cure behavior of elastomer modified, reactive vinylester resin based carbon fiber reinforced composites is characterized through the use of DSC analysis. It is shown that both fiber loading level and percentage of sizing used on the fiber have a significant effect on factors such as cure rate, degree of cure, time to maximum cure rate, rate constant and exponent of the auto-catalytic equation. Increases in sizing levels are shown to result in changes of cure rates and peak temperatures resulting from possible changes in curing mechanisms in the vinylester system under consideration. The effects have special significance as related to the use of carbon-vinylester composites for the fabrication of large scale primary structural components through processes such as RTM, Resin Infusion and Pultrusion.
