TO THE QUESTION OF THE DEVELOPMENT OF PRESSING MODE FOR LAMINATED PCMs BASED ON PREPREG
The main approaches and methods for determining the optimal temperature-time regimes for pressing laminated PCM based on prepregs are presented. The main stages of pressing regimes of layered PCM based on prepregs are considered from the point of view of the three main technological parameters of pressing (temperature, pressure, time). The pressing regimes for fiberglass PCM based on a melt epoxy binder fiberglass prepreg has been selected. It was shown that correction of pressing regimes depends on thickness of the molded workpiece. Investigations of the process of curing the prepreg at different heating rates on DSC have been carried out and the kinetic parameters of the binder curing reaction have been calculated. The simultaneous solutions of heattrausfer and chemical problems are carried out to take into account the thickness of the composite.
