Abstract: The honey comb sandwich construction is one of the most valued structural engineering innovations developed by the composite industry. Used extensively in many industries like aerospace, transportation rails, etc. In this study a stainless steel chosen a face sheet and copper is a core material. Honeycombs are most often an array of hollow hexagonal cells with thin vertical walls Copper Honeycomb is low density permeable material with numerous applications. The defining characteristic of these Honeycombs is a very high porosity; typically 75-95% of the volume consists of void spaces. Static three-point bending tests were carried out in order to investigate load and deflection variations. The theoretical load and defections in copper honey comb sandwich panel values is adapted and compared with experimental and simulation results .Metallic Honeycombs have found a wide variety of applications in heat exchangers, energy absorption, flow diffusion and lightweight optics. Copper honeycomb is used in numerous engineering and scientific applications in industry for both porosity and strength.
