摘要

To apply induction heating to CFRP curing and molding, this paper proposes a finite element analysis method based on dynamically superimposed coupled magnetic fields and a macro–micro coupling mechanism. This method reveals the impact of various component properties and structures on heating and heat transfer, analyzes the coupling between the dynamically superimposed magnetic field and the changes in multiple physical fields during heating, and simulates the improvement in temperature field uniformity. Experimental results confirm that this heating method effectively improves temperature field uniformity and achieves CFRP curing and molding. Experimental results demonstrate the effectiveness of the proposed induction heating mode in improving temperature field uniformity. Around 200 s of heating, the temperature field uniformity at local positions of the material gradually improves, especially within the effective area corresponding to the coil, showing a significant enhancement in uniformity. CFRP curing and forming are successfully achieved under this heating mode.
