Preconditioning theory for reactive compression molding

The preconditioning analysis for reactive compression molding uses a numerical simulation to calculate temperature and cure changes.

During a preconditioning analysis, only temperature and cure equations are solved; pressure-velocity equations are not solved. The temperature is solved using an equation similar to that for reactive molding simulations.

Curing is analyzed by solving equation 11.

where is the degree of cure, and and are fitting parameters.

The terms and are described by:

where is temperature, and , , , and are fitting parameters.

The heat transfer between the resin and the mold or environment is given by equation 2:

where is the heat transfer, is the area, is the temperature of the resin, and is the external temperature.
