In the paper, an original construction of a coaxial flange for measurements of shielding efficiency of composite materials is presented. The measurement procedure is conceived as a differential method to suppress influence of a flange. Attention is turned to measurements of carbon composites used in aerospace industry. The studied materials exhibit a significant ability to shield electromagnetic radiation. The shielding efficiency is rising with material thickness and with the number of fiber-to-fiber contacts. The optimal composite structure consists of 4 layers of carbon composite; more layers do not influence the shielding efficiency significantly.
