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 undercombined 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
