Abstract: A method of fabricating a concrete slab system places bed of a first concrete on a base. The bed has a top surface, a bottom surface, and edge surfaces. The bed is exposed to a drying environment such that the top surface develops shrinkage cracks and portions of the bed separate from the base. A force applied to the top surface induces non-shrinkage cracks in the bed that extend to the bed's bottom surface. Non-concrete material is placed on the bed's top surface and on each of its edge surfaces. The non-concrete material and bed are covered with a second concrete having stretchable fibers mixed therein.

Abstract: A load bearing panel member having a first portion, a second portion, and an appearance surface portion is formed by injection molding such that the first portion includes a plurality of ribs forming a grid pattern on the first portion and another plurality of ribs extending toward the periphery of the first portion which may be non-orthogonal to each other and to the ribs forming the grid pattern. An internal channel may be formed within each of the non-orthogonal ribs by injecting a gas into the rib during the molding process forming the panel. An appearance surface portion attached to the first portion and second portion of the panel member forms an integral hinge between the first and second portions of the panel member. The panel member may be configured as a floor panel of a vehicle.
