FIBER-REINFORCED ALLOY FORMED BODY COATED WITH POLYDOPAMINE AND FUNCTIONAL NANO-MATERIAL

摘要

The present invention relates to a fiber-reinforced alloy formed body coated with polydopamine and a functional nano-material. 1) Carbon fiber, aramid fiber, or cellulose nano-fiber is coated with a functional nano-material having one or more selected among grapheme, CNT, silver nano, silver nano-wire, titanium dioxide, and phosphorine, and then viscous polydopamine is coated to form fiber (carbon fiber, aramid fiber, or cellulose nano-fiber) coated with the polydopamine and the functional nano-material. Then 2) selected fiber is formed in single fiber or in a sheet form to insert the fiber into a mold formed in a design form of a desired product and press a molten magnesium alloy or a molten aluminum alloy formed by heating a magnesium alloy or an aluminum alloy to melt the magnesium alloy or the aluminum alloy by a plunger to inject the molten magnesium alloy or the molten aluminum alloy into the mold in which the fiber exists to tightly combine, cool, press, solidify, and form (die casting) the fiber (fiber selected among the carbon fiber, the aramid fiber, and the cellulose nano-fiber) coated with the molten magnesium alloy or the molten aluminum alloy, the polydopamine, and the functional nano-material to form a functional fiber-reinforced alloy formed body of a design form of a desired product in various fields such as an electronic device (a mobile phone, a laptop, a tablet PC, a computer), an automobile, an exterior and a part of an airplane, a heat radiation plate, sports equipment, and a bicycle exhibiting a property of the fiber (fiber selected among the carbon fiber, the aramid fiber, and the cellulose nano-fiber) coated with the magnesium alloy or the aluminum alloy, the polydopamine, and the functional nano-material.;COPYRIGHT KIPO 2017
