SIMULATION AND ANALYSIS OF SHEET MOLDING COMPOUND COMPRESSION MOLDING FLOW

Automatic computer simulation of phenolic sheet molding compound(P-SMC) compression-mol ding flow is realized by finite element step-by-step computing method, and compared with the result of experiments. Finite element computing and postanalysis programs have been written. The compr ession mold filling process, time and pressure needed of PSMC in a closed mold are analyzed. It will be of theoretical significance to mold design and to the optimization of the techno logical parameters in the compression molding of sheet molding compound.
