Characterization of Mechanical and Physical Properties Of Polyurethane Cored Sandwich Structure
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2017, Vol 5, Issue 6
Abstract
In this modern era, most of the conventional engineering materials are replaced by composite materials. Composites are widely used in automobiles, aircraft and marine applications because they are related to light weight, high strength to weight ratio, corrosion resistance flexibility, high impact strength. In its most basic form the composite material is one which is composed of at least two elements working together. A sandwich structured composites is a special class of composite materials that is fabricated by attaching two thin but stiff skins to a light weight but thick core. This project study focuses on the fabrication and characterization of sandwich composite panels using glass fiber composite skin, polyurethane foam as a core material and epoxy resin as an adhesive material. The main objectives are to characterize the physical and mechanical properties and to elucidate the effect of face sheet thickness and core thickness on the flexural strength of a sandwich structure under three point bending and also attempt will be made to characterized reinforced sandwich composites in terms of water absorption. The images of the fractured specimens showed, crack propagation starts from the interface between the core material and face sheet and moves towards the centre of the core to the lower face of the face sheet.
