Abstract
Essentially nonflammable, moldable, strong laminates formed of alternating layers of cured magnesium oxycement and a fibrous web, e.g., paper formed of cellulosic, glass or synthetic resin fibers or mixtures thereof. The magnesium oxycement may contain a suitable filter, the surfaces of the laminate may be modified and composites may be formed with a wide variety of core materials. The laminates are made by coating the fibrous webs with a reactive slurry of a magnesium salt solution and magnesium oxide. The fibrous web materials used are impermeable to the extent that no appreciable amount of the magnesium salt solution is absorbed and no appreciable amount of the magnesium oxide is filtered out onto the surface or into the intertices of the web.
