- China’s J-35 stealth fighter, showcasing domestically developed metamaterial coatings that achieve an RCS smaller than a human palm.
- Cutting-edge manufacturing techniques such as 3D printing and additive manufacturing that facilitate the creation of complex stealth structures.
- Integration of metamaterials with thermal management systems to ensure stealth without revealing thermal signatures, extending operational capabilities.
- Global adoption among leading defense contractors including Lockheed Martin and Raytheon, as well as platforms like the F-35 and DDG-1000.
FibreCoat’s Radar-Absorbing Composite
FibreCoat has made significant strides with its new radar-absorbing composite material. The composite features:
- Material Composition: Bicomponent multifilament yarns mixed with engineered blends of PMMA, carbon nanotubes, and Alucoat fillers.
- Performance: Demonstrates the ability to absorb radar across a wide spectrum, particularly in the X-band (8–12 GHz), with performance improvements of up to 100 times over existing materials.
- Advantages: The composite is lightweight, flexible, broadband, and recyclable, simplifying production while reducing weight compared to traditional radar-shielding materials.
- Status: Currently in the proof-of-concept stage, with field tests projected to conclude by 2025 and commercial availability expected shortly thereafter.
- Applications: This technology can be utilized in aircraft, tanks, spacecraft, drones, and for electromagnetic shielding.
The J-35 Stealth Fighter: A Game Changer
China’s J-35 stealth fighter represents a significant leap in indigenous stealth technology. Key features include:
- Stealth Features: Incorporates advanced metamaterial coatings and strategic shaping to achieve an RCS smaller than a human palm.
- Platform Capabilities: As a carrier-capable fifth-generation fighter, the J-35 is designed for superior combat performance.
- Industry Significance: This development underscores China’s advancements in integrating metamaterials into military aviation, marking a strategic milestone in global defense technology.
