<p>The disclosure is based on the discovery that load-bearing systems (10) and materials handling systems having excellent physical properties (e.g., high capacity/weight ratio, durability) can be manufactured from composite materials. In general, the disclosure features load-bearing systems (e.g., a pallet or a skid, or a unit that can be attached to similar units to form superstructures such as piers, docks, bridges, scaffolding, or marine flooring). The load-bearing systems include a body (11), having at least three (e.g., three, four, six, or more) intersecting walls (14) and a plurality of structural members (18) (e.g., beams, ribs, or other elements) extending between two of the walls, and support members (12) (e.g., legs, feet, vertical spacers) extending downwardly from the body. At least part of the load-bearing system can include a composite of thermoplastic resin and a fibrous organic material.</p> |
