MUMBAI, India, July 11 -- Intellectual Property India has published a patent application (202541060873 A) filed by Akshaya College Of Engineering And Technology, Coimbatore, Tamil Nadu, on June 25, for 'alkaline treatment of natural fibers for enhanced fibre - matrix interfacing in eco -frinedly composites.'
Inventor(s) include Dr. D. Deepa; Mr. S. Barathkumar; Mr. K. Kathiravan; Mr. R. Vijayrahul; and Mr. J. Vikram.
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: "The present invention relates to a method for enhancing the fibre-matrix interface in eco-friendly composite materials by applying an alkaline treatment to natural fibers such as banana, jute, and Borassus flabellifer. The process involves soaking the fibers in a sodium hydroxide solution to remove impurities like lignin and hemicellulose, thereby increasing surface roughness and exposure of hydroxyl groups. This enhances adhesion with polymer matrices such as epoxy, resulting in composites with superior mechanical properties, thermal stability, and reduced water absorption. The treated fibers are used in a hand lay-up fabrication method to create hybrid laminates tailored for strength and durability. The invention provides a low-cost, scalable, and environmentally responsible alternative to synthetic fiber composites, supporting applications in automotive, packaging, and construction sectors. The improved interfacial bonding and sustainability aspects make this system an ideal solution for waste valorization and rural-based composite manufacturing, addressing both environmental and performance limitations in current composite technologies."
