In this work, a new route for improving the absorbing performance of glass fibers (GFs) composites by introducing the reduced graphene oxide (RGO)/polypyrrole (PPy)/RGO coatings through the self‐assembly method and then the in‐situ polymerization method was proposed. The corresponding microstructure and electromagnetic parameters were measured by scanning electron microscopy, X‐ray photoelectron spectroscopy, and vector network analyzer. The result indicated that the RGO/PPy/RGO coatings can adjust the absorbing performance of GFs composites by its synergistic effect, thus exhibiting optimum impedance matching degree and high conduction loss ability. The minimum reflection loss value of the synthesized RGO/PPy/RGO/GFs composite can reach −55.8 dB with the thickness of 4.3 mm, and the effective absorption bandwidths (≤−10 dB) covered the entire X‐band. This work proved that the RGO/PPy/RGO coatings can be used to adjust the radar absorbing performance of GFs composites.

This study introduces an innovative approach to enhance the absorption capabilities of skin‐core dual‐domain structure radar‐absorbing materials (SDSRAM) composed of thin‐ply laminates and honeycomb. The upper skin laminates consist of transmissive skin and impedance matching layer. The impedance matching layer was hot‐pressed using functionalized absorbed thin‐ply glass fibers prepregs, flaked carbonyl iron powder (FCIP) and multi‐walled carbon nanotubes (MWCNTs) as the absorber. The lower skin was manufactured using carbon fiber‐plated nickel. The core is prepared by honeycomb modified (HCM). The permittivity and permeability of the skin laminates and the HCM were measured by wave‐guide method. The impact of FCIP/MWCNT on the electromagnetic (EM) parameters of the thin‐ply laminates and the influence of MWCNTs on the permittivity of the honeycomb were investigated. Microwave absorption properties of SDSRAM were assessed through the measurement of reflection loss (RL) using the arch method and simulated using the microwave simulation software CST studio suite 2020. Experimental verification was conducted to confirm the absorbing performance. The results show that the effective absorption bandwidth (RL < 10 dB) of SDSRAM covers the frequency range of 2.2–18 GHz, with a maximum absorption intensity of −42.5 dB. The introduction of the thin‐ply laminates caused a shift in the peak of the reflectance curve toward lower frequencies.Highlights Functionalized absorbed glass fibers were prepared using fiber spreading functional sizing integrated process. A new skin‐core dual‐domain synergistic modulation absorbed structure was developed with thin‐ply laminates and modified honeycomb. Its broadband absorption mechanism was discussed. Desired broadband absorption performance was acquired with thin thickness.
