Aramid Honeycomb Core Is Used in Wave Absorbers

Aerospace – The radar domes, air intakes, leading edges of wings, etc., of stealth aircraft (such as the B-2), unmanned aerial vehicles, and satellites are used to reduce RCS.

Ships and warships – The masts, compartments, and other parts of the warship have achieved electromagnetic compatibility and stealth capabilities.

Ground equipment – Stealth tanks, radar stations, communication vehicles, and their shelter compartments, etc.

Electrocommunication – Microwave anechoic chamber, electromagnetic interference shielding box, etc.

Why choose aramid honeycomb?

This is a highly professional and cutting-edge application field. Aramid honeycomb is used in absorptive devices, which is a typical "structural-functional integration" design. It ingeniously combines lightweight and high-strength structural materials with stealth/ electromagnetic compatibility functions.

. Excellent specific strength and specific stiffness: Kevlar honeycomb is one of the lightest structural materials in the world, but its strength-to-weight ratio and stiffness-to-weight ratio are extremely high. This is of crucial importance in fields such as aerospace and high-speed aircraft, where weight sensitivity is extremely high.

. High design flexibility: The aperture, wall thickness, and height of the honeycomb can be flexibly designed to adjust the mechanical and electromagnetic properties of the absorber. For instance, using a honeycomb with gradually varying apertures can achieve wider bandwidth absorption.

. Good fatigue resistance and impact resistance: The aramid material itself has good toughness, and the honeycomb structure made from it can effectively absorb impact energy.

. High-temperature resistant and flame-retardant: Aramid fibers (such as Nomex and Kevlar) inherently possess excellent heat resistance and flame retardancy, and are suitable for use in high-temperature working environments.
