MUMBAI, India, Aug. 17 -- Intellectual Property India has published a patent application (202641096208 A) filed by Gudlyf Mobility Pvt Ltd on August 09, 2026, for Mechanically Coupled Terminal Fitting And Associated Fabrication Method For Reinforced Pressure Vessels.
Inventors include Ajeet Babu Kumar Parasumanna; and Kumar Seshaier Parasumanna.
The application for the patent was published on August 14, 2026, under issue no. 33/2026.
Abstract: A mechanically coupled terminal fitting (300) and an associated fabrication method for reinforced pressure vessels, particularly Type IV composite gas cylinders, are disclosed. The terminal fitting comprises a metal boss body (301) produced by additive manufacturing with an integral anchoring region (302) incorporating a reentrant undercut microstructure and an axial gas port (307). A surface of the boss body is prepared to a predetermined roughness (303) and provided with an electroplated adhesion-promoting interlayer (304) before being integrated with a polymer liner (308) during moulding within a mould (309). The anchoring region is configured with backward-facing barbs (305) for blow moulding or an open lattice (306) for rotational or injection moulding, thereby establishing mechanical interlocking together with enhanced interfacial adhesion. The resulting mechanically coupled terminal fitting provides a gas-tight, fatigue-resistant, and high-strength interface between the metal boss and polymer liner, el
