The degree of cure of a vinyl ester resin used for RTM as a function of cure time is given by the following equation.

(a) Assuming that the presence of fibers does not influence the cure kinetics, determine the temperature that should be used to achieve 80% cure in 1 min cure time.

(b) What is the cure rate at 80% cure in (a)?

(c) What temperature should be used if the cure rate needs to be doubled at 80% cure? What will be the cure time now?
