Carbon nanotube/glass fabric composites for radar absorption

Synthesized carbon nanotubes (CNTs)/glass fabrics (GFs) composites using an interface design strategy is an effective method to fabricate radar absorbing structures. In this work, CNTs/GFs composites were prepared by the electrophoretic deposition (EPD) method, and the influence of deposition voltage, deposition time, and the concentration of CNTs solution on the microstructure, electromagnetic parameters, and absorbing properties of CNTs/GFs composites was studied. The results indicated the deposition content of CNTs can be controlled by the EPD parameters and thereby realizing the regulation of absorbing performance of the CNTs/GFs composites. The minimum reflection loss (RL) of the synthesized composites can reach – 69.3 dB with the thickness of 2.3 mm when the concentration of CNTs was 1 g/L, the deposition voltage was 16 V and deposition time was 4 min. Such good absorbing performance demonstrate that the CNTs/GFs composites can be applied as a promising candidate for radar absorbing structures.
