    • An environmental enclosure structure formed of a cement-based slurry infiltrated fiber composite material. The enclosure structure is a box-like enclosure (V) formed of the composite material which is produced by first placing a plurality of individual short fibers or fiber mats of organic or inorganic materials into a form to create a bed of fibers substantially filling the form and having a predetermined fiber volume density and then adding a cement-based slurry mixture includes a composition of Portland cement, fly ash, water, a high-range water reducer (superplasticizer), and may also include fine grain sand, chemical admixtures, and other additives. Due to its fiber volume density and method of manufacture, the resulting structure has thinner walls (10, 11), greater strength, and a gross weight significantly less than conventional reinforced and pre-stressed concrete structures of the same size, and a much higher bending capacity approximating that of structural steel.

    • A metal fiber reinforced composition (22) and its method of fabrication. Metal fibers (12) are created from stock material. The metal fibers (12) are straightened and cut into short lengths. Each of the metal fibers (12) has an average maximum diameter of between 0.005 millimeters and 0.2 millimeters, and a cut length no greater than two- hundred times the average maximum diameter. A volume of a curable composition (16) is provided. The metal fibers (12) are mixed into the curable composition (16) to create a fiber reinforced composition (22). The fiber reinforced composition (22) is then formed into a selected shape, such as a construction element. The selected shape is then cured. Since the metal fibers (12) are dispersed uniformly throughout the selected shape, curing or re-heating of the selected shape can be facilitated using an induction coil that heats the various metal fibers within the selected shape.
