Abstract
A composite pressure vessel that includes a monolayer liner and a reinforcing structure arranged on top of the liner. The liner is made by injection moulding and includes at least two shells weldable together. Each shell is made of a polymer composition including at least 45% by weight of an aromatic polyamide relative to the total weight of the polymer composition, and at least 10% by weight of an aliphatic polyamide relative to the total weight of the polymer composition.
