MUMBAI, India, May 29 -- Intellectual Property India has published a patent application (202621028542 A) filed by Parth Chetankumar Shah; Dr. Jashvantkumar Devabhai Rathod; and The Maharaja Sayajirao University Of Baroda, Vadodara, Gujarat, on March 10, for 'a hybrid fiber-integrated cementitious composite.'
Inventor(s) include Parth Chetankumar Shah; and Dr. Jashvantkumar Devabhai Rathod.
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 present invention discloses a hybrid fiber-integrated cementitious composite that achieves improved mechanical properties, superior bendability and fracture resistance through the combined use of micro and macro fibers. The composite includes cement, siliceous fine aggregate, micro polyester fibers and macro polypropylene fibers and superplasticizer for improved workability and uniform fiber distribution. Micro polyester fibers enhance matrix densification and micro-crack width control, while macro polypropylene fibers inhibit macro crack propagation resulting into super ductility, and energy absorption. Composite consists of cement:sand ratio 0.5, water/cement ratio of 0.35, 4% volume fraction of micro polyester fiber, 3% volume fraction of macro polypropylene fibers exhibited superior structural ductile performance and fracture toughness which plays key roll in ductile performance of the structure. Experimental evaluation revealed significant improvements, with the hybrid mix (4% polyester + 3% polypropylene) showing up to 310% higher flexural strength and 242% higher fracture toughness compared to the plain matrix."
