An improved three-dimensional structure and method and system of making same is provided, wherein the method for forming the three-dimensional structure comprises: coating a filament with a curable resin; directing a first portion of the coated filament around a plurality of pins fixed to and extending outwardly from a frame, the coated filament directed to intersect according to a pre-set pattern, the coated filament forming a first filament layer; directing a second portion of the coated filament about said pins forming one or more subsequent filament layers aligned and in contact with the first filament layer, the filament layers collectively forming a filament stack, the filament stack having a predetermined height and defining the intersecting panel elements; and curing the curable resin such that it hardens and retains the individual filament layers forming the filament stack in a three-dimensional shape.

A cover for a utility vault and a method for making such covers. The cover is formed from fiberglass reinforcement layers and a polymer mix matrix. The reinforcement layers include a bottom reinforcement layer, one or more edge reinforcement layers, and a top reinforcement layer. A first portion of the edge reinforcement layer overlaps a portion of the bottom reinforcement layer and a second portion of the edge reinforcement layer overlaps a portion of the top reinforcement layer. The reinforcement layers are formed from fiberglass fabric and may include fiberglass layers whose fibers are oriented quadraxially. The polymer mix impregnates the fabric layers and forms the bulk of the cover. The polymer matrix bonds the reinforcement layers so that forces applied across the top and bottom layers are communicated to the edge reinforcement layer. The polymer matrix includes a thermoset polymer resin and an expanded glass bead filler.
