▎ 摘　　要

NOVELTY - A tank comprises a wall formed of a filament wound carbon fibre reinforced polymer with a graphene nanomaterial filler dispersed in the polymer adhesive matrix, where the tank is formed to provide one or more integrated hard points for mechanical connection to other structural elements of the frame or for supporting other non-load bearing components of the structure, and the hard points comprise fixing units integrated into the filament winding and over molded by the polymer adhesive. USE - Tank for storing volatile gas under pressure ADVANTAGE - The tank is linerless, is formed to store the gas under pressure in a range from 300-1000 bar, is formed to store compressed hydrogen, nitrogen, or oxygen in a liquid or gas phase. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a structure which comprises a frame for bearing static and dynamic forces from internal and external loads, where the frame comprises a tank, the tank being an active load bearing structural element configured as a stressed member in the frame. DESCRIPTION OF DRAWING(S) - The drawing shows a cross-sectional view of a tank for storing volatile gas under pressure Tank (140) Wall (143) Chamber (145) Mandrel (147) Hardpoints (149)
