1. A method for manufacturing tanks for storing or containing a fluid under pressure, comprising the steps of:
(a) providing a liner having a cylindrical portion with two ends and two dome portions at respective ends of the cylindrical portions;
(b) independently fabricating a tube of fibre filament reinforced material by pullwinding; and
(c) fitting the tube of fibre filament reinforced material onto the liner such that at least the cylindrical portion of the liner is enclosed by the tube of fibre filament reinforced material;
wherein the enclosing fibre filaments are made of carbon, aramid, glass fibres, or any combination thereof.
