为了解激光辐照对玻璃钢材料微波透射特性的影响,对激光照射后的样品进行了分析研究.通过红外谱分析了烧蚀样品的微观结构变化,用扫描电镜分析了损伤细观形貌,结合结构和物理性能的变化讨论了微波透射性能变化.结果表明,激光烧蚀会导致玻璃钢材料微观组分的变化、宏观结构的改变,形成烧蚀层、碳化层、热解层和原始层组成的多层结构.其中,碳化层、烧蚀层的微观构成发生了显著变化,形成了微波的散射和吸收机制,进而导致了微波传输性能下降.

The change of microwave transmission on the laser ablation glass-fiber resin composite,GFRC,was invested by means of researching on the laser irradiated sample.The IR spectra was analyzed to describe the microstructure alter,and the surface picture was observed with the scanning electron micrograph.The measurement of the microwave transmission was discussed on the variety of the structure and the physical properties.It was shown that laser ablation result in the change of GFRC composition and form.It was recombined as multilayer structure with ablation layer,carbonization layer,pyrogenation layer and primary layer.Distinct change in both ablation layer and carbonization layer lead to the microwave scatterring and absorption.The microwave transmission was reduced in the mechanics.
