It is proposed a composite pressure vessel comprising a monolayer liner and a reinforcing structure arranged on top of the liner, the liner being made by injection moulding, the liner comprising at least two shells weldable together. Each shell is made of a polymer composition comprising 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. |
