Abstract:Multi-physics model of microwave heating-laser heating-thermal radiation-flow heat transfer-solid mechanics was established using simulation software. We studied the temperature field disrtibution and thermal stress of the carbon fiber tow with a diameter of 1mm heated by laser. We also studied the effects of different laser power on the temperature field and thermal stress.At the same time, we propose that the temperature field distribution and the thermal stress can be adjusted with the co-heating process via laser and microwave for the first time.The simulation results show that the combination of laser heating and microwave heating can improve the temperature field distribution of the carbon fiber tow and effectively reduce the thermal stress during the heating.
Keywords:microwave heating  laser heating  numerical simulation  thermal stress  uniformity
