Cone Shaped Absorbing Honeycomb For Reducing Electromagnetic Interference In Darkrooms
1. Descriptions of Absorbing aramid honeycomb core:
Aramid honeycomb core is a core material in the field of electromagnetic testing. The darkroom laboratory has strict requirements for the wideband absorption ability, structural stability, and environmental adaptability of absorbing materials. Our R&D team focuses on industry pain points and has spent several months tackling them. By optimizing the selection of honeycomb core materials, innovating the formula of absorbing coatings, and improving composite processes, we have successfully created a series of absorbing honeycomb products that combine high performance and high cost-effectiveness.
The absorbing honeycomb is made of aramid honeycomb, aluminum honeycomb, and fiberglass honeycomb as substrates, combined with specially designed absorbing fillers, which can achieve a reflection loss of ≥ 20dB in the frequency range of 30MHz-40GHz. Its absorption performance in the low frequency band is significantly improved compared to traditional materials, and it also has high specific strength and lightweight characteristics. The density is only about 0.3g/cm ³, which can effectively reduce the load of darkroom buildings and meet the needs of large-span space laying.

3. Absorbing aramid honeycomb core has several advantages:
Lightweight: The honeycomb structure itself has a high porosity and low material usage, which can significantly reduce the overall weight. It has obvious advantages in fields such as aerospace where weight reduction is highly required.
High stiffness/strength: The hexagonal structure of the honeycomb has good mechanical properties and can effectively disperse loads under pressure, shear forces, etc., while also possessing structural load-bearing capacity.
Absorption characteristics: It can absorb electromagnetic waves from multiple frequency bands, has a wide range of applications, and can cope with electromagnetic interference or radar detection needs in different scenarios.
Functional integration: It can simultaneously achieve multiple functions such as electromagnetic absorption, structural support, and lightweight, realizing the integration of functions, reducing the number of components, and simplifying the design and manufacturing process.
Material compatibility: It can be composite with various absorbing materials (such as ferrite, carbon based materials, etc.) and structural materials (such as composite materials, metals, etc.), and the material combination can be adjusted according to different needs.
Environmental adaptability: It can maintain stable performance in harsh environments such as high temperature, high humidity, vibration, etc., and has good weather resistance and reliability.
