Abstract
Sandwich structures are stiff and are light in weight simultaneously hence they have got a wide range of engineering applications specially in transportation, building materials, aerospace and aviation industry, motor sports etc. In the present investigation a composite-honeycomb sandwich structure is analyzed under static loading using FEM software ANSYS. An epoxy-carbon laminate is bonded to aluminum alloy honeycomb so that the laminate act as the skin and the honeycomb is the core of the sandwich structure. This resulting sandwich structure is analyzed under bending and compressive load with clamped and cantilever boundary conditions. The analysis is done to study the effect of using 3-different basic cell shapes of the honeycomb core viz. triangular honeycomb core, square honeycomb core and hexagonal honeycomb core. Further the effect of varying cell parameter of hexagonal honeycomb core is studied. In clamped-bending and cantilever bending configuration, hexagonal honeycomb core is found to be the strongest among prescribed cores however in compressive load condition square honeycomb is found to be the strongest.
