Aircraft material usually uses light and strong metal alloys. This type of material will be damaged quickly when used in the marine environment, one of which is caused by corrosion which can erode the aircraft's structure. Therefore, a replacement material is needed for winged ships with the criteria of being a strong and light material, having a specific thickness, and being resistant to corrosion. Sandwich composite materials consisting of epoxy and woven roving E-glass fiber as the facing layer and polyurethane foam as the core material have been investigated. The materials with four types of panels having different fiber geometrical orientations of the facing were fabricated using vacuum assisted resin infusion (VARI) method. Tensile and flexural tests were performed on the materials to understand their mechanical properties and failure mechanisms. The resulting mechanical properties were best obtained from the panel facing having four layers of fiber orientation of 0°, 90°, +45°, -45° with tensile and flexural strengths of 28.18 and 5.75 MPa, respectively. Scanning Electron Microscope (SEM) examination was subsequently performed and showed that the failure of the materials started from the core and propagated to the facing layer.
