摘要：
Induction heating technology is an effective method to achieve low energy consumption and efficient curing and molding of carbon fiber reinforced polymer (CFRP). Improving the uniformity of the CFRP induction heating temperature field is the key to ensure the molding quality. And the uniformity of the temperature field in the left of the coil is to ensure the overall temperature uniformity of the material key. According to the principle of electromagnetic heating, an analysis model of CFRP finite element multi-field coupling was established. The comparison and analysis of the temperature field heating and distribution of the simulation calculation and the experimental process proves that the simulation can accurately simulate the temperature field distribution of CFRP induction heating. According to the entropy theory of the image, the uniformity of the temperature field is expressed by the size of the entropy, and the quantitative analysis of the uniformity of the CFRP induction heating temperature field is realized. The coil diameter and the distance between the coil and the material are calculated and studied through the finite element model. The influence of the uniformity of the temperature field, the relationship curve between the uniformity of the temperature field in the left area and the coil diameter and material spacing is obtained, which provides a theoretical basis for the selection of coil diameter and material spacing for the combined coil to uniformly heat CFRP. © 2021, Editorial Office of Acta Materiae Compositae Sinica.
