Abstract

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.

基于动态叠加磁场宏微观组合的CFRP感应加热

为了将感应加热应用于CFRP固化成型，本文提出了一种基于动态叠加耦合磁场和宏观微观耦合机理的有限元分析方法。该方法揭示了不同部件性能和结构对加热和传热的影响，分析了加热过程中动态叠加磁场与多个物理场变化之间的耦合关系，模拟了温度场均匀性的提高。实验结果证实，该加热方法有效提高了温度场均匀性，实现了CFRP的固化成型。实验结果证明了所提出的感应加热方式在改善温度场均匀性方面的有效性。加热200s左右，材料局部位置温度场均匀性逐渐改善，特别是线圈对应的有效区域内，均匀性明显增强。在此加热模式下，CFRP成功固化成型。

期刊介绍： Applied Composite Materials is an international journal dedicated to the publication of original full-length papers, review articles and short communications of the highest quality that advance the development and application of engineering composite materials. Its articles identify problems that limit the performance and reliability of the composite material and composite part; and propose solutions that lead to innovation in design and the successful exploitation and commercialization of composite materials across the widest spectrum of engineering uses. The main focus is on the quantitative descriptions of material systems and processing routes. Coverage includes management of time-dependent changes in microscopic and macroscopic structure and its exploitation from the material''s conception through to its eventual obsolescence.
