This study addresses the technical challenge of achieving lightweight stealth integration in aerospace equipment by proposing an innovative multilayered electromagnetic metamaterial structure based on carbon fiber/ aranmid fiber composites.Through a multi-level impedance matching design，the structure achieves broadband high-efficiency absorption at an ultrathin thickness of 3.3 mm.A hierarchical fabrication process was employed to construct functional metamaterial layers：aramid fiber-reinforced epoxy resin composites served as dielectric materials，while carbon fiber-reinforced epoxy resin composites acted as conductive materials.The NRL Arch method was adopted to characterize the absorption performance of the sample across the 2 to 18 GHz frequency range. Experimental results demonstrate that the multilayered composite metamaterial exhibits two absorption peaks at 7.03 GHz and 9.84 GHz within the optimized frequency band，with a maximum planar reflectivity of -18.82 dB.Furthermore，the sample displays notable directional sensitivity.When the orientation is rotated from 0° to 90°，the planar reflectivity increases by 3 dB.The proposed methodology provides a technically viable pathway for developing next-generation lightweight stealth equipment， offering both theoretical innovation and engineering applicability.
