Study on Radar Absorbing Properties of Impure Sm2O3/Acrylate Coatings

The development and application of the stealth material technology are one of the key factors to develop the stealth technology. The painting type of stealth material has the properties of simply process, usableness and easy regulate, so it has been extensive concern. In the paper the impure Sm2O3/acrylate coatings were prepared using Sm2O3 and carbon nanotubes powder and their microstructure was studied by SEM. Furthermore it was studied on radar absorption properties in 1-18GHz and mechanics properties of the coatings. It is proved that the absorption effect of the coatings is the best when the thickness coating is 1.2mm and its solid dosage is 50wt%. Meanwhile mechanics properties of the films are very good.
