Micro Part Reinforced by Addition of Unidirectional Short Fibers in Laser Photolithography by Applying Magnetic Field : Layered Thin Film with Aligned Short Fibers(Machine Elements, Design and Manufacturing)

Abstract

The purpose of this research work is to produce micro part reinforced by unidirectional short fibers by laser photolithography. Ferromagnetic short fibers are added to liquid photopolymer. By applying magnetic field to this mixture, the axes of the short fibers are aligned along the direction of the magnetic field. Then, the photopolymer is solidified by the irradiation of UV laser in the desired shape. The solidified thin films with aligned short fibers are layered until the desired height is obtained. The surfaces of the solidified thin layers are observed by scanning electron microscope and the possibilities of the reinforcing effect between each layer are examined. Several examples of micro structure reinforced by unidirectional short fibers are produced by this method.
