Abstract
A method for manufacturing a tank for pressurized gas includes producing a composite insert comprising a fiber reinforcement embedded in a thermoset matrix, placing the composite insert in a mold, and overmolding, over at least part of a surface of the composite insert, with an overmolding polymer. The method further includes cooling/curing, and further comprising, between the producing step and the overmolding step, a step of depositing a bonding polymer on at least part of the surface of the composite insert.
