Abstract: An internal casing for a pressurized fluid storage tank for a motor vehicle includes: a hollow body includes a layer made of a first polymer material; and a neck arranged on the hollow body and delimiting an opening of the hollow body, the neck receiving an interface part mounted on the neck in a sealed manner by a gasket arranged between the neck and the interface part. The neck is made of a composite material composed of a second polymer material loaded with reinforcing fibers, the composite material having a deformation resistance than that of the first polymer material. The neck is joined to the hollow body by molecular entanglement of polymer chains of the first polymer material and polymer chains of the second polymer material. Methods for manufacturing such an internal casing, and a storage tank including such an internal casing are disclosed.
