Abstract
Rubber is a typical viscoelastic polymer and has a low thermal conductivity. The main consequence is heat generation and leads to a temperature rise called heat build-up of the rubber material when subjected to cyclic deformation. Numerical modelling to predict the physical processes of heat transfer, typically complicated, in the curing of rubber using the finite difference method are presented in this study. The transport phenomena during curing of rubber was modeled using basic equations without considering the values and variation in the shrinkage stress and strain. One code developed with the Python open source language and its mathematical libraries, was proposed in this study and applied to solve this problem. The numerical results agreed with simulations presented previously in literature. The deviation obtained for temperature values is around 1% in the heating and cooling phases when comparing with results of the literature. Future work should include shrinkage model and solve the more complicated equations about heat and mass transfer considering the water concentration variation to improve the formulated model. The inclusion of the vapor phase in the drying air would also help improve the physical model.
