研究了切向气流和氮气流作用下碳纤维增强复合材料（CFRP）层合板在连续激光辐照下的羽流特性。用红外热像仪测量了羽流的温度。用激光消光法研究了羽流相对质量浓度的变化。利用红外热像仪测量了碳纤维复合材料的前表面发射率修正温度图，以估计羽流的影响。羽流中的最高温度与羽流对激光的吸收密切相关，而与羽流的燃烧效应无关。两种气流下羽流温度、材料表面温度和热影响区的差异都是由于气流下羽流燃烧的影响。随着羽流质量浓度的降低，这些差异逐渐消失或不再增加。研究结果可为激光加工和激光损伤的应用提供参考。
The characteristics of plumes during continuous wave laser irradiation of laminated carbon fiber reinforced plastics (CFRP) under tangential air flow or nitrogen gas flow are investigated. The temperature of the plume is measured by the infrared thermal imager. The change in relative mass concentration of the plume is studied by the laser extinction method. The front surface emissivity-corrected temperature maps of CFRP are measured by the infrared thermal imager to estimate the influences of plumes. The highest temperature in the plume is closely related to the absorption of the laser by the plume rather than the combustion effects of the plume. The differences of the plumes, temperature, the material surface temperature and the heat affect zone, under the two different kinds of gas flows, are all due to the effect of the burning of the plume under air flow. As the mass concentration of plumes decreases, these differences gradually disappear or no longer increase. The results of this work can be referenced for the application of the laser processing and the laser damage.
