MUMBAI, India, July 11 -- Intellectual Property India has published a patent application (202541040734 A) filed by KLE Technological University, Hubballi, Karnataka, on April 28, for 'multi-layered hybrid nano-composite stiffener for concrete structures in optimizing steel.'
Inventor(s) include Dr. Hunashyal Anand M; Dr. Musale Akshata; Dr. K. A. Roopa; Ms. Jalgar Sandhya R; and Dr. Halyal Shivraj M.
The application for the patent was published on July 11, under issue no. 28/2025.
According to the abstract released by the Intellectual Property India: "A novel approach to reinforcing concrete structures using a hybrid, three-level reinforcement system. The goal is to enhance strength, ductility, and durability while optimizing material usage. The study investigates reinforcement at the macro (carbon fibers), micro (carbon black powder), and nano (functionalized MWCNT's) levels. Through extensive testing-including mechanical evaluation, microstructural analysis, and simulation techniques-the proposed material demonstrates improved properties such as higher tensile and flexural strength, increased toughness, and better crack resistance. The innovation leads to a 25% reduction in steel and 30% reduction in concrete usage while maintaining structural efficiency. The developed nano-based admixture also improves corrosion resistance and workability. The research has resulted in academic publications, patents, and a market-ready product, potentially benefiting engineers, architects, and construction firms."
