摘　　要：为了摸清激光辐照橡胶类气象气球等空中目标的效应规律,为后续开展外场试验提供依据,本文进行了激光-载荷联合作用下天然乳胶材料烧蚀性能实验研究。采用1085 nm光纤固体激光器,对天然乳胶材料进行了激光辐照效应实验,研究了激光和载荷共同作用下材料的烧蚀性能,结果得到:材料主要发生热解、烧蚀穿孔和断裂破坏;在同等功率密度光斑辐照条件下,材料破坏时间随载荷增加先增加后减小;在同等加载条件下,材料破坏时间随辐照功率密度增加而减小。In order to find out the effect law of laser irradiation on rubber weather balloons and other airborne targets,and to provide a basis for subsequent field tests,an experimental study on the ablation property of natural rubber materials under combined action of laser and mechanical loading is conducted in this paper.A 1085 nm fiber-optic solid-state laser is used to study the ablation property of the material under the combined action of laser and mechanical loading.The results show that the material is mainly damaged by decomposition,ablation hole and fracture.Besides,while the sample is irradiated under a same power density,the material damage time firstly increases and then decreases with the loading increasing.Under the same loading conditions,the material damage time decreases with increasing irradiation power density.
