COMBINED STRUCTURE WITH HIGH CONDUCTIVITY AND HIGH STRENGTH AND MANUFACTURING METHOD THEREOF

摘要

PURPOSE: A composite material with high conductivity and high strength and a preparation method thereof are provided to ensure high conductivity and high strength according to the property of a selected material. CONSTITUTION: A method for preparing a composite material comprises the steps of: forming a photosensitive layer(112) on the surface of a bulk material(110); forming a preset pattern(114) on the photosensitive layer so that a part of the surface of a bulk material is exposed; forming a groove pattern(120) of a curved shape by etching the exposed part; and filling the groove pattern with a high conductive material(130).
