MUMBAI, India, May 29 -- Intellectual Property India has published a patent application (202641061682 A) filed by Christ University, Bengaluru, Karnataka, on May 15, for 'coconut fiber reinforced concrete composition for enhanced shear strength and ductility.'
Inventor(s) include Antony Varghese; and Dr. Sujatha Unnikrishnan.
The application for the patent was published on May 29, under issue no. 22/2026.
According to the abstract released by the Intellectual Property India: "The invention relates to fiber-reinforced concrete, and particularly to a coconut fiber reinforced concrete composition and method for preparation thereof for improving shear strength and ductility. The composition comprises a cementitious matrix including ordinary Portland cement, fine aggregate, coarse aggregate, and water, and a plurality of treated coconut fibers provided as discrete randomly dispersed discontinuous reinforcement, the fibers having lengths selected from 25 mm - 75 mm and being incorporated at 0.5% to 2.0% by mass of cement after pre-soaking. In a hardened concrete body, the fibers form a distributed crack-bridging network through fiber-matrix and aggregate-paste interfacial regions to transfer stress by adhesion, frictional pull-out resistance, and mechanical interlock. The method includes a layered charging and mixing sequence, moulding, and vibration compaction to obtain substantially uniform fiber distribution, wherein pre-soaking and controlled mixing improve fiber dispersion and interfacial bonding, including in an L-shaped specimen configured for shear-dominant loading."
