MUMBAI, India, May 1 -- Intellectual Property India has published a patent application (202641026438 A) filed by M. Chrispin Das; Kalaimegam. D; Vinisha. J; Prashantshende; Ra Vichandran. M; and Dialak, M. Karungal, Tamil Nadu, on March 6, for 'novel system enhancement of milling characters of kenaf fiber and flax fiber filler boron carbide reinforced epoxy resiin ly 556 composite.'
Inventor(s) include M. Chrispin Das; Kalaimegam. D; Vinisha. J; Prashantshende; Ravichandran. M; and Dialak.
The application for the patent was published on May 1, under issue no. 18/2026.
According to the abstract released by the Intellectual Property India: "The present invention relates to a hybrid natural fibre reinforced polymer composite comprising kenaf fibre and flax fibre as reinforcements, boron carbide as a ceramic filler, and epoxy resin L Y 556 as the matrix material. The natural fibres are subjected to alkali treatment to improve fibre-matrix interfacial bonding, and the composite is fabricated using a hand lay-up technique followed by room-temperature curing. The incorporation of boron carbide filler enhances the structural integrity and machinability of the composite. The invention further provides a method for optimizing the milling characteristics of the developed composite by controlling machining parameters such as spindle speed, feed rate, and depth of cut. The optimized milling conditions result in reduced surface roughness, minimized fibre pull-out, and improved material removal rate. The developed composite offers a lightweight, eco-friendly, and cost-effective material solution suitable for various engineering and industrial applications."
