ABSTRACT:
A pressure vessel of fibre-reinforced plastic has an essentially cylindrical central portion (10) and two end portions (11, 12) and is preferably provided with a gas-tight liner (14). The central portion comprises a tangential winding (20) of the fibre material, in which the fibre material is oriented in an essentially tangential direction and an axial winding (21), located outside the tangential winding, of fibre material in which the fibre material is oriented in an essentially axial direction and the fibre material of which extends out into and forms a reinforcement of the fibre material in the end portions. The central portion, including its tangential winding and its axial winding, in each of its parts (10a, 20a, 21a) located nearest to an end portion, is formed with a diameter which decreases in a direction towards the end portion. That part (20a) of the tangential winding having a diameter decreasing in a direction towards the end portion preferably has an end (20b) facing the end portion, the wall of the end having an at least substantially wedge-shaped cross-section.
