Abstract:A homogenized reaction-diffusion model is used to study the mechanism of frontal polymerization in glass-fiber-reinforced dicyclopentadiene-matrix composites by studying the effects of the material properties of the reinforcing phase on the velocity, temperature, and width of the reaction front. This model is also nondimensionalized and expressed in a general form in terms of two nondimensional parameters dependent on the material properties and cure kinetics of the composite system. The general nature of this formulation is exploited to generate a large dataset of reaction front velocities for resin chemistries that are similar to dicyclopentadiene (DCPD), which serves as the reference resin in this work. Finally, the homogenized reaction-diffusion model is used to investigate the temperature spike that occurs when two reaction fronts merge. A method to estimate the energy associated with the thermal spike is developed and applied to size a metal heat sink introduced to eliminate the thermal spike.
