建立激光表面纹理化热模型,分析了在纹理化中起关键作用的表面熔化过程,计算出表面温度、穿透深度、熔化深度、相面移动速度等物理量。

This work characterizes the laser-induced periodic surface structure of PET fiber by 308 nm excimer laser. The heat model on enthalpy was set up for interaction between the laser and PET. The melt phenomenon was important for surface structure formation. The surface temperature, melt depth and melt depth dependences of time and liquid/solid interface move velocity were numerically calculated.
