Disclosed herein is a portable panel having numerous favorable characteristics. The panel comprises a core having a length, a width, a first side and a second side. A first fiber layer is attached to the first side while a second fiber layer is attached to the second side. A first polyurethane layer is impregnated in the first fiber layer while a second polyurethane layer is impregnated into the second fiber layer. A first skin is attached to the first polyurethane layer while a second skin is attached to the second polyurethane layer. The panel can be used in the manufacture of tables, flooring, risers, stages, bleachers, and the like.

What is claimed is: 1. A panel comprising: a core having a length, a width, a thickness, a perimeter section having a reduced thickness, a first side and a second side; a first fiber layer attached to the first side; a second fiber layer attached to the second side; a first polyurethane layer impre
What is claimed is: 1. A panel comprising: a core having a length, a width, a thickness, a perimeter section having a reduced thickness, a first side and a second side; a first fiber layer attached to the first side; a second fiber layer attached to the second side; a first polyurethane layer impregnating the first fiber layer; a second polyurethane layer impregnating the second fiber layer; a first skin attached to the first polyurethane layer; a second skin attached to the second polyurethane layer; and a frame operatively engaging the core and including projections forming a channel shaped to accept the perimeter section, the projections shaped to mechanically engage the reduced thickness of the perimeter section. 2. The panel of claim 1, wherein the core further includes a plurality of openings, the opening substantially uniformly spaced along the width and length. 3. The panel of claim 1, wherein the frame includes a general T-shape and the projections and channel correspond to the T-shape. 4. The panel of claim 1, wherein each projection includes at least one tooth engaging the reduced thickness. 5. The panel of claim 4, wherein each projection includes an exterior surface and an external thickness measure between the exterior surfaces, the external thickness is reduced at a location corresponding to the location of the teeth on the projections. 6. The panel of claim 1, wherein the first skin and the second skin each include a metal layer. 7. A portable table, the portable table comprising at least one support leg; and a planar surface attached to the at least one support leg the planar surface including: a core having a length, a width, a first side and a second side; a first fiber layer attached to the first side; a second fiber layer attached to the second side; a first polyurethane layer impregnating the first fiber layer; a second polyurethane layer impregnating the second fiber layer; a first laminate skin attached to the first polyurethane layer; a second laminate skin attached to the second polyurethane layer; a thickness; and a perimeter section including a reduced thickness portion less than the thickness of the planar surface; and a frame engaging the planar surface and including projections forming a channel shaped to accept the perimeter section, the projections shaped to mechanically engage the reduced thickness portion of the perimeter section. 8. The portable table of claim 7, wherein the perimeter section further includes an intermediate thickness portion extending from the reduced thickness portion opposite the body portion of the planar surface, the intermediate thickness portion larger than the reduced thickness portion and less than the thickness of the planar surface. 9. The portable table of claim 8, wherein the reduced thickness portion and the intermediate thickness portion of the perimeter section are mechanically pressed to a thickness less than the thickness of the planar surface. 10. The portable table of claim 7, further including a plurality of support structures positioned between the first and second laminate skins. 11. The portable table of claim 10, wherein at least one of the support structures includes a length substantially equal to the length of the core. 12. The portable table of claim 10, wherein the at least one support leg includes a polarity of foldable support legs with each foldable support leg attached to one of plurality of support structures. 13. The portable table of claim 10, wherein at least one of the support structures is positioned in the core between the first and second polyurethane layers. 14. The portable table of claim 7, further including a column and a column support shaped to accept and removable attche te column to the planar surface, the column support formed within the planar surface and positioned between the first and second fiber layers. 15. The portable table of claim 7, wherein the second skin is composed of a sound absorbing material. 16. The portable table of claim 7, wherein the planar surface includes an indented area shaped to accept the foldable support legs and position the foldable support legs substantially coplanar with the planar surface when the foldable support legs are closed. 17. A reversible portable floor, the portable floor comprising a plurality of panels, each panel including: a core having a length, a width, a first side and a second side; a first fiber layer attached to the first side; a second fiber layer attached to the second side; a first polyurethane layer impregnating the first fiber layer; a second polyurethane layer impregnating the second fiber layer; a first skin attached to the first polyurethane layer; a second skin attached to the second polyurethane layer; a thickness; a perimeter section having a neck and a head; and a frame surrounding the core, the frame including projections forming a channel shaped to accept the perimeter section, the projections shaped to mechanically engage the head and neck of the perimeter section. 18. The reversible portable floor of claim 17, wherein each projection of the frame includes at least one tooth engaging the neck of the perimeter section. 19. The reversible portable floor of claim 18, wherein each projection of the frame further includes at least one stabilizer engaging the head of the perimeter section. 20. The reversible portable floor of claim 17, further including a metal portion extending substantially the width and length of the core. 21. A method of constructing a panel comprising: a) providing a frame having a projections forming a channel b) providing a core having thickness and a perimeter with a reduce thickness c) placing the perimeter of the core within the channel of the frame and compressing the projections of the frame into engagement with the perimeter of the core; d) attaching a first fiber layer to a first side of the core and a first side of the frame; e) attaching a second fiber layer to a second side of the core and a second side of the frame; f) impregnating a first polyurethane layer in the first fiber layer; g) attaching a first skin to the first polyurethane layer and the frame, the first skin and frame constraining the first polyurethane layer as it cures; h) impregnating a second polyurethane layer in the second fiber layer; and i) attaching a second skin to the second polyurethane layer and the frame, the second skin and frame constraining the second polyurethane layer as it cures. 22. The method of claim 21, wherein the method is performed without a mold. 23. A method of constructing a portable table comprising: a) providing a planer surface, the planar surface having a core having first and second fiber layers attached to first and second sides of the core, first and second polyurethane layers impregnated to one of the first or second fiber layers, first and second skins attached to one of the first or polyurethane layers, the core fiber layers, polyurethane layers and skins forming a planar surface body thickness; b) compressing a portion of the planar surface to form a perimeter having a thickness less than the planar surface body thickness; and c) forming a frame around the planar surface, the frame mechanically engaging the perimeter of the planar surface. 24.
