NUMERICAL SIMULATION ON TEMPERATURE FIELD FOR PREPOLYMERIZATION PROCESS OF PMI FOAM CORE MATERIAL

Abstract

Abstract: Inappropriate temperature control may bring about implosion when polymethacrylimide (PMI) foam is prepared by two-step method. In this paper, we measured the critical temperature of the implosion and the changing trend of the polymerization system temperature in the process of preparing PMI with methylacrylic acid (MAA) and methacrylonitrile (MAN). Then the effects of ambient temperature and the size of the prepolymer on the temperature field of the polymerization system were studied by simulating the temperature distribution of the polymerization system in ABAQUS.

Key words: PMI foam, implosion, temperature field, simulation
