In conventional electromagnetic shielding areas, where metal materials are mainly used, polymers and composite materials are drawing attention as a substitute material for it. Composites mechanical properties are changed in accordance with the stacked alignment angle, the number of stacked layers and the layered material. By laminating the carbon fiber pre-preg and the Wire Mesh the test specimens were created. The bending tests were performed and by using an S-S Curve the bending strength and bending stiffness were analyzed. Keywords : autoclave molding, bending test, carbon fiber reinforced plastic, wire mesh I. Introduction Carbon fiber reinforced plastic (CFRP) is advantageous in strength, rigidity and anti-corrosion characteristics compared with metal materials, and has excellent mechanical characteristics for diverse types of loads. Accordingly, it is widely used for aviation, automotive and marine industries, resulting in active studies and also a lower price suitable for its application to diverse sectors. In addition, it is also used as a shielding material against the electromagnetic wave emitted from electric and electronic appliances which are in increasing demand [1]. In the application of CFRP, the rigidity and strength characteristics can be controlled by direction of material, manufacturing method and lamination thickness according to the required structure. In composite materials, the properties of fiber and matrix material differ, and it is very important to determine the rigidity characteristics. However, it is determined by test because it is not easily calculated with theoretical equations [2]. In this paper, the metal wire mesh was used to make test specimens according to the number of lattices and lamination sheets, and the bending strength was tested to ensure the reliability of the mechanical properties. Thus, the use of composite material was examined for the applications in the shielding material industry, which mostly uses metal materials, and other diverse sectors [3,4]. CF-(Number1) and SUS(Number2)-(Number3) in this paper are abbreviations. CF represents CFRP 3K prepreg; Number1, the number of its lamination layers; SUS, the STS304 wire mesh; Number2, the number of lattices of STS304 wire mesh, and Number3, the number of its lamination layers. II. Theoretical Background 2.1 CFRP(Carbon Fiber Reinforced Plastics) High strength, high elastic composite materials with carbon fiber as reinforcement are generally called CFRP. It has excellent characteristics as structural material. It is known that its specific strength is six times that of steel, and its specific modulus is three times that of steel [5]. It is divided into thermosetting and thermoplastic material according to the injected resin, and has diverse characteristics according to its types. Figure 1.Schematic of carbon composites
