Behavior of Sandwich Composites under Edgewise and Flatwise Compression; Effect of Variation of Fibre Architecture and Core DensityBy Manujesh B. J, R. Vijayalakshmi Rao, Prajna M. R., Jnanesh N. A., Antony P. J.
Abstract: The present paper is focused on the fabrication of foam–cored sandwich composites using manual hand layup technique and testing under in-plane compression. The sandwich construction comprises of polyurethane foams of five varied densities with E-glass fibre in vinylester resin as face sheets. Four different varieties of E-glass fibre are used. As compression properties are of critical importance during the design of lightweight structures, an attempt is made to study the …

Flexural Characterization of Sandwich Composites; Effect of Varying PU Foam Density and E-Glass Fabric on Flexural StrengthBy Manujesh B. J, R. Vijayalakshmi Rao, Prajna M. R.
Abstract: AbstractThis paper presents the results of an extensive investigation on flexural behavior and failure mechanisms of sandwich composites with polyurethane (PU) foam core and glass reinforced vinylester as facesheet. The sandwich structures with PU foam of varied density and glass fibres of different architecture are tested under three point bending. The experimental values of face bending strength (FBS) and core shear stress (CSS) are evaluated. Effect of core density and …
