Abstract

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