Development of a mathematical model of two-phase polymer curing systems

The formation a heterogeneous structure in two-phase elastomer composites was studied. Computer modeling of curing system in a set of five reaction–diffusion equations was carried out. In numerical experiments it is shown that density of the crosslinking of the entire system increases slower than the cure in the absence of curative’s diffusion, and the cure rate and the total degree of crosslinking of the composite as a whole is reduced

Development of mathematical model of curing two-phase polymeric systems

During research of kinetics of curing of two-phase elastomeric composites the new kinetic model, allowed to explain heterogeneity of the grid which was formed in this process of curing crosslink was developed. In numerical experiments it is shown that average extent of sewing together of all system increases more slowly, than when curing in lack of diffusion of vulcanizing substances, and the speed of curing and the general extent of sewing together of a composite as a whole decreases
