Effect of fibre arrangement on temperature field of CFRP induction heating

Abstract

Because the characteristics of carbon fibre composites (CFRP) are directly related to the arrangement of fibre bundles, changing the orientation of fibres generates a shift in temperature field distribution during material heating. As a result, a finite element meso analysis model of CFRP induction heating is developed based on the actual laying mode and equivalent electro-magnetic thermal characteristics, and the variation laws of vortex current, calorific value, and temperature field distribution in CFRP with various fibre arrangements are simulated to investigate the role of fibre laying mode in the induction heating process. Simultaneously, the induction heating experiment shows that the finite element model developed in this paper can accurately calculate the distribution of temperature field of various types of CFRP.
