Abstract

In this paper, ultrafast laser ablation of Aramid Fiber Reinforced Plastic (AFRP) and its application in satellite reflector antenna was studied. Intrinsic properties for transmission spectrum were measured. For material processing the influence of pulse energy fluence, pulse overlapping rate and laser wavelength (from the NIR to the NUV) on appearance qualities (namely the blackening of cutting edge) were studied. It was shown that the wavelength played an important role in controlling the machining defects such as blackening. While NUV wavelength long pulse (10 ps) laser generated a smooth cutting cross-section with material’s intrinsic colors, the NIR wavelength resulted in a carbonization-prone ablation, even if the femtosecond laser was considered. The possible mechanisms involved were discussed. The application of laser trimming of satellite antenna was demonstrated.
