| Research 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 apparatus for applying the magnetic field is composed of four electromagnets in horizontal directions and one in vertical direction. The magnitude and direction of the magnetic field generated by these electromagnets can be changed. The degree of the alignment of the short fibers is examined using this apparatus. Several examples of micro structure reinforced by unidirectional short fibers are produced by this method.
