Development and Study of Flat Wise Compressive Strength of Eutectic Al-Si Alloy Fly-ash Cenosphere Open Cell Foamed Composite Core Sandwich Panel

In this work Eutectic Al-Si Alloy Fly-ash Cenosphere Open Cell Foamed Composite were produced by melt route i.e., core casting method. AFSP (Aluminium Foam Sandwich Panel) was further fabricated by open aluminium foam and two face aluminium sheet. The Flatwise compression strength is a fundamental mechanical property of sandwich cores that are used in design purpose. Core properties are usually required in a direction normal to the plane of facing sheet as the core is placed in a sandwich construction. The Flatwise compressive behaviour of AFSP studied. The Flatwise compressive strength of AFSP is found to be 45.1MPa and compressive strength of only Al foam is 25.7MP. It is observe that compressive strength of AFSP higher than of compressive strength of aluminium foam alone. Relative density, density and porosity of the foam produced are 0 .35and its density is .92g/cm 3 and 65% respectively.
