摘要

Electromagnetic induction heating technology offers distinct advantages in the curing and forming of carbon fiber-reinforced polymer (CFRP) composites, including non-contact heating, environmental friendliness, and rapid temperature rise, thereby significantly promoting the expansion of CFRP applications and their broader utilization. In this study, a mesoscopic model was established to characterize the carbon fiber plies and resin matrix independently. The model reveals the mechanisms by which the fiber stacking sequence, material properties, and fiber volume fraction affect the evolution of the temperature field, degree of cure, and stress distribution during induction heating. Furthermore, short-beam shear tests were conducted on CFRP specimens with a plain-weave structure under induction heating, demonstrating that electromagnetic induction can effectively achieve both curing and forming of CFRP. The proposed model provides a theoretical basis for optimizing CFRP molding processes with different layup configurations and material properties.
