The aim of this research paper is to study the flexural and shear properties of foam based sandwichcomposites. Polyisocyanurate foam is used as the core of composite and glass fabric reinforced epoxy based laminates areused as the skin of the sandwich, the density of polyisocyanurate foam is 250kg/m^3. Skin to core weight ratio of 2:1 and 1:1are maintained for the panels fabricated separately with the vacuum bagging technique.Specimen with varying span length todepth ratio of 21:1, 16:1and varying skin to core weight ratio of 2:1 and 1:1 are tested using an UTM machine. The threepoint bending tests are carried out for finding maximum bending stress maximum deflection shear stress and bendingstrength and other flexural properties.The testing results are compared and analysed in depth to find the influence of the coredensity and span to depth ratio on the flexural and shear properties of the sandwich composite structure
