Recent progress in computer simulation applied in the automaticpressure gelation (APG) process for epoxy casting systems

摘要

The authors present fundamental information about the first stepsof modeling the nonlinear gelation and curing phenomena of an epoxyresin system based on available material data with respect to therelevant chemical reactions and energy balance. The necessaryassumptions concerning the filling of the tool, the heat transfer andshrinking of the material are discussed. In the case of simple shapedparts, such as plates, rods and post insulators, the results of computersimulations are available and are visualized. The propagation of thegelation and curing zone, including the time dependent temperaturedistribution, can be displayed on the screen. Comparison betweencalculated and measured data from moulding experiments is in fairly goodagreement
