Abstract
A fiber-reinforced resin wall of a collapsible shipping container large enough and strong enough for shipping about 300 gallons of liquid is made by compression molding a laminate formed of a glass fiber mat sandwiched between resin webs. This material is arranged in a central region of a compression mold cavity for a wall of the container so that the flow of material during compression molding runs laterally from a central region to side edge regions of the molded wall. Horizontal corrugations extend in the same direction as the lateral flow of material and are not intersected by any transverse ribs so that the flow along the horizontal corrugations is not deviated from the lateral direction. This laterally orients the fibers and optimizes the strength of the wall in the horizontal direction, which is important for bulk shipping requirements.
