Method of manufacturing composite structures with variable electromagnetic characteristics according to variation of resin content and Radar-absorbing structure comprising the same

摘要

The present invention relates to a method of producing a composite material having various electromagnetic properties according to the content of a resin and an electromagnetic wave absorbing structure comprising the resin and the nanoparticle resin and a nanofiber resin and a reinforcing fiber, A step of laminating a forming part such as a peel ply, a perforated film and a bleeder to the prepreg, applying pressure to the laminated prepreg and the forming part, Wherein the ratio of the polymer resin and the nanomaterial to be discharged into the breather varies depending on the resin content due to the filtering effect of the nanomaterial, including the autoclave forming step of controlling the electromagnetic characteristics of the resin A method for manufacturing a composite material having various electromagnetic characteristics according to content and a method for manufacturing It relates to an electromagnetic wave absorbing structure. The method for producing a composite material having various electromagnetic characteristics according to the present invention and the electromagnetic wave absorbing structure including the composite material according to the present invention can be applied to various electromagnetic wave absorbing structures There is an advantage to be able to do.
