Abstract
The main development route in wave absorption technology is to develop new absorbing materials to achieve comprehensive requirements such as thin thickness, light weight, broadband coverage and high loss capability. However, as far as the current development trend of materials and structures concerned, it is nearly unrealistic to realize the integration of wave absorbing and load bearing or other compatible functions only through designs of multi-layer composites. Therefore, based on the concept of multi-scale collaborative design of materials and structures, this paper proposes a new type of honeycomb reinforced structure that can bear loads and absorb microwaves. The wave absorber designed in this structure is epoxy resin filled with carbon nanomaterials and carbonyl iron. According to the simulations, this design has broadband coverage and high loss capability, which can achieve full-band coverage of lower than − 0 dB within the 1–20 GHz frequency range, with its loss peak exceeding −30 dB, and the average level is about −20 dB; At the same time, this design may improve mechanical properties of the honeycomb structure to a certain extent due to its sheet structures inside, which is expected to achieve the integration of load bearing and microwave absorbing.
