要約

Thermal and curing reaction coupling has a great influence during composites molding process. An algorithm of solving complicated structure composites curing process with coupled anisotropic transient thermal and curing reaction kinetics formulation based on unstructured gird finite volume method is presented. The spatial item of heat diffusion equation of anisotropic composites is discretized by unstructured grid finite volume method, and time item is discretized by Euler implicit scheme. Curing kinetics equation is calculated by Euler explicit scheme, and obtained the heat source of the energy equation through the curing reaction rate which subjected to temperature distribution and corresponding manufacturing process plans, thus realizing the two-way coupling of thermal and curing reaction. Finally, this method is verified correctness and reliability through several classical examples for which prior results and experimental data are available in the literature, at the same times, it shows that the method presented can deal with the numerical simulation of the coupled thermal and curing reaction kinetics of composites molding process with complicated structure.
