MUMBAI, India, March 13 -- Intellectual Property India has published a patent application (202421105215 A) filed by Goel, Manmohan Dass; Shirbhate, Payal Anil; and Umbharatwala, Madhav, Nagpur, Maharashtra, on Dec. 31, 2024, for 'a blast mitigation sandwich structure.'
Inventor(s) include Goel, Manmohan Dass; Shirbhate, Payal Anil; and Umbharatwala, Madhav.
The application for the patent was published on March 13, under issue no. 11/2026.
According to the abstract released by the Intellectual Property India: "The present invention relates to a blast mitigation sandwich structure designed for enhanced energy absorption and structural integrity under explosive loading. The structure comprises a stainless steel facesheet and backsheet (SS-304), bonded to a cellular core using a high-strength adhesive. The core options include an empty aluminum honeycomb, polyurethane (PU) foam-filled aluminum honeycomb, and PU foam-filled high-strength paper honeycomb. The combination of metallic and foam materials provides superior energy absorption through plastic deformation of the core and compression of the PU foam filler. The stainless steel sheets resist lateral loads and reduce momentum transfer, while the adhesive layer ensures robust bonding and shear force transfer. Experimental analysis demonstrates the structure's ability to resist deformation on the backsheet, even under high strain rates caused by blast loads. This invention offers a promising solution for blast load mitigation, balancing weight reduction, energy absorption, and structural performance."
