The sandwich structure composed of E-glass fibre, diviny cell foam and epoxy resin were subjected to three point bending test to assess bending strength. Three types of foam cores with different density (60 kg/m3, 80 kg/m3 and 100 kg/m3) were investigated. The effect of foam density on flexural rigidity was assessed. It has been observed that the sandwich structures with higher foam density withstand a higher bending load& higher shear strengthshowless flexuralstressandflexural moduluswhencomparedwithlow density core
