Abstract

The results of modeling the kinetics of the heating process of a 20 mm thick GFRP part are presented. Exothermic effects related to the peculiarities of epoxy binder curing were taken into account during modeling. Using Siemens NX software, the temperature distribution along the thickness of the fiberglass sample was determined. It was found that the curing process of composite structures of large thickness is significantly influenced by self-heating of oligomer, as well as the changing value of volumetric heat capacity in the process of polymerization.
