Abstract

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.

Key words: microwave heating, laser heating, numerical simulation, thermal stress, uniformity

摘要：

利用仿真软件建立微波加热-激光加热-热辐射-流动传热-固体力学多物理场模型，研究了激光加热直径1mm碳纤维丝束的温度场分布与热应力大小，以及不同激光功率对于温度场与热应力的影响。同时，首次提出激光加热与微波加热结合的方式调节温度场分布与热应力大小的方法，仿真结果显示激光加热与微波加热结合的方式可以改善碳纤维丝束温度场的分布，有效降低丝束加热过程中的热应力。
