Mathematical Modeling of Unsaturated Isophthalic Resin’s Curing cycle

Fiber reinforced plastics (FRP) products are light weighing and strong. These materials find extensive applications in various engineering fields and also as sensor metarial. Curing of this resin is a key to obtain FRP Products. Various factors including Gel time (T ) and peak exothermic temperature (T ) are the critical factors that gel peak directly affect the curing process. T is the indicator for the commencement of setting (polymer cross-linking) while T gel peak talks about the shrinkage and cracking of the polymer. This research work finds the T and T for the curing of UP gel peak resin based isophthalic acid. The Catalyst MEKP (methyl ethyl ketone peroxide). The accelerator cobalt octoate (Cost) were used for the curing process. Results showed strong interactions between the process variables mentioned above. The process was anoptimization to achieve a combination of T and T within the regime of experimentation. gel peak Mathematical models were developed using regression for both peak temperature and gel time. Confirmatory experiments were performed to validate the predicted results.
