This method is particularly adapted for making tanks of different diameters. A plurality of arcuate forming sections are provided by forming a flexible sheet of a panel section against rigid arcuate forming segments having a degree of curvature corresponding to that of the inner surface of the tank to be formed. Turnbuckles are used to form the flexible sheets against the segments. These forming sections are then accurately located on a base circumference location and rigidly interconnected to make a rigid cylindrical forming structure, against which the fiber reinforced resin is layed up to make the tank structure. The panel sections each comprise a sheet having a pair of vertical edge bracing and connecting flanges by which the panel sections are joined, and a plurality of locating brackets which engage the forming segments to locate the forming sections with respect to one another. |
