Temperature control method and system for pultrusion die

The invention relates to the field of preparation of composite materials, in particular to a temperature control method and system for a pultrusion die. According to the method disclosed by the invention, corresponding heating curing curves are fitted through different types of materials to be cured, and different heating areas are divided on a pultrusion mold by utilizing the heating curing curves; temperature control is carried out on different heating areas, so that accurate control over the temperature of each heating section in the dynamic curing process of the composite material is achieved; measuring errors generated due to the fact that the pultrusion die cannot collect the internal temperature, the internal and external temperature transmission efficiency and the like are eliminated by obtaining an internal and external temperature transmission model when the no-load pultrusion die is heated and optimizing the temperature transmission model of the corresponding heating section; and meanwhile, the hea
