The rib form comprises a cardboard blank folded into a trapezoidal shape and having overlapping opposite longitudinal edge portions of the blank glued together and forming the shorter of the two parallel sides of the trapezoidal shape. Peripheral slots evenly spaced along the rib form are cut through the longer of the parallel sides and through the two angular sides of the trapezoidal shape.
A hollow elongate cardboard rib form that can be positioned on a glass fiber reinforced plastic tank and over which a glass fiber reinforced plastic reinforcing rib can be formed to reinforce the walls of the tank, the rib form having a trapezoidal cross-sectional shape, having a double thickness of cardboard at a shorter of two parallel sides of the trapezoidal shape, said double thickness comprising overlapped and glued together opposite longitudinal edge portions of a starting flat blank from which the rib form is made, and having a plurality of longi...
