Sandwich plate core material development for civil engineering and ship structures is required to devise light weight but high-flexure strength material. This paper discusses development of sandwich plate consisted of synthetic resin based core material and steel faceplates applicable for flat plate of ship deck structures. The core material was selected because it was made up of relatively low-cost and easy-to-find materials. The sandwich materials were tested to ensure that these materials met the Det Norske Veritas standard. The sandwich plate was then applied for designing deck structure of ship. Results of this study showed that the sandwich plate density was up to 47.6% lighter than the density of steel. Yet it was able to withstand 13.9% to 36.7% larger bending stress than the faceplate steel material; thus the contribution of core material developed in this study to the sandwich bending strength was confirmed. Application of the sandwich plate material for roro passenger ship design demonstrated that it would simplify the ship construction and could reduce the self-weight of parallel middle body of ship structure by 13.08 %. Thus it might increase payload of the ship appreciably.
