ABSTRACT:
Assembly of a fiber reinforced resin tank includes joining a plurality of prefabricated arcuate wall panel sections by elongated joiner panels extending along the vertical seams between adjacent wall sections to form the perimeter of a cylindrical tank. The wall sections have a plurality of openings adjacent the vertical sides and the joiner panels have columns of transversely spaced pairs of protrusions for coupling with the openings in adjacent panel sections. The joiner panel is able to pass circumferential hoop stress from one panel section to an adjacent panel section by providing effective clamping between the two panels through the use of continuous filament and/or geometrically oriented glass or other fibers placed into a hooked shape so the fibers extend between each pair of spaced protrusions and curve into the protrusions so the fibers extend along the protrusions. Additionally, the wall sections include criss-crossing diagonal fibers so there are crossing fibers between the openings of the wall section and the vertical edge of the wall section thereby preventing a force applied by the protrusion in the opening from tearing the wall section.
