    • A composite wall of reinforced synthetic resin, for retaining both gases and liquids, that is particularly adapted for underground use in gasoline storage tanks, which are resistant to external compression forces; such as, water flooded earth. The wall is characterized by a very high stiffness factor, produced by a combination of spaced ribs of filament wound material and that are hollow, retained on top of a chopped strand-resin wall, where the chopped strand bridges the spaces between the ribs. A process involving the steps of forming a tank end cap on a mandrel and thereafter supporting the end cap in space and laying up a resin-rich wall layer of chopped strand and resin in joined relation to the end cap, and curing the wall partially; then forming over the outer surface of the wall a hollow shell structure which comprises a combination of woven roving and filament wound layers superimposed and saturated with wet resin. Then completely curing the composite wall to produce a monolithic structure.

    • A method of forming ribs on a revolving shell in generally parallel circumferentially extending relationship. Each rib is built over a strip form having a cross section that is an isoceles trapezoid that is positioned with the base or wide parallel side against the shell, and the narrow parallel side forming the crown. A strip of glass fiber mat wetted with resin is carried by a band of individually tensioned strands which are attached to the revolving shell, and are wrapped therearound by the revolving shell. The band of strands is divided into three groups, the center of which is positioned over the crown and the outside groups of which are positioned over the inclined surfaces of the strip form. As the revolving shell pulls the individually tensioned strands over the rib, the outside groups pull the mat strip against the inclined sides of the rib form, and thereafter slide down the inclined surfaces of the mat to smooth out wrinkles. Finally the outside groups come to rest over the portions of the shell on opposite sides of the rib form to anchor to mat firmly in engagement with the shell and in tight engagement with the rib form. The materials are preferably fed to the underside of the revolving shell so that the strands may also carry the mat and the rib form to the surface of the revolving shell.
