[Abstract]:A kind of combustible composite material based on metal foil was prepared in view of the fact that the traditional infrared decoy could not effectively resist the infrared / millimeter wave guided weapon. In order to improve the infrared radiation performance and millimeter wave scattering performance of the foil, the preparation process optimization, material additive selection and foil material optimization technology were studied. The preparation conditions of combustible chaff were optimized. The temperature of combustible chaff during combustion was studied by using infrared thermal imager and infrared spectrometer. The results show that the infrared radiation performance of combustible chaff can be improved effectively by selecting appropriate material and proportion and shape and size. Based on the theory of infrared radiation and the characteristics of combustible chaff, several additives were selected, and the temperature during the combustion of combustible chaff was studied by using infrared thermal imager and infrared spectrometer. The effects of radiation intensity and spectral radiance on the properties of the combustible chaff with better infrared radiation performance were obtained. The maximum combustion temperature was 913.2 鈩，
