As frontal polymerization is being considered as a faster and more energy efficient manufacturing technique for polymer-matrix fiber-reinforced composites, we perform finite-element-based numerical study of the initiation propagation front in dicyclopentadiene (DCPD). The transient thermochemical simulations are complemented by an analytical steady-state front, allowing to draw direct link between cure kinetics model key characteristics i.e., velocity characteristic length scales. second part this focuses on prediction temperature spike associated with merger two fronts. thermal peak, which might be detrimental properties polymerized material, due inability heat highly exothermic reaction dissipated when fronts merge. analysis investigates how amplitude affected degree at time merger.
