MUMBAI, India, Feb. 27 -- Intellectual Property India has published a patent application (202641019028 A) filed by Tara Uav Private Limited, Hyderabad, Telangana, on Feb. 19, for 'polymer nano-composite as radar absorbent material.'
Inventor(s) include Dr. Ayagara Aravind Rajan; and Mr. Subramanyam Vijayasaradhi.
The application for the patent was published on Feb. 27, under issue no. 09/2026.
According to the abstract released by the Intellectual Property India: "A multifunctional polymer nanocomposite-based radar absorbing structure (RAS) is disclosed for reducing radar cross-section (RCS) of defense and aerospace platforms, particularly UAVs, in the X-band (8-12 GHz). The structure integrates electromagnetic wave absorption with structural load-bearing capability, comprising a glass fiber-reinforced polymer (GFRP) substrate overlaid with one or more nano-modified shell layers. Carbon black and/or carbon nanotubes are dispersed in an epoxy matrix via sonication, impregnated into glass fiber fabrics, and cured to form thin, lightweight skins achieving reflection loss below -10 dB. Single-layer or multi-layer configurations enable tunability of permittivity, impedance matching, and mechanical properties. The manufacturing process is compatible with standard composite techniques, offering weight savings, durability, and retrofit potential over conventional coatings. Analytical optimization guides design for superior stealth performance."
