Abstract

In recent days, the aluminium honeycomb sandwich panels are commonly used in industry application due to its high energy absorption capability of honeycomb structures. This paper studied the simulation and application of nature fiber / epoxy aluminium honeycomb for impact performance analysis. Aluminium honeycomb widely used in automotive and aeroplane industry. Honeycomb cores are applied to resolve minimal deflections for the panels and maximal energy absorption for sandwich panel. Aluminium honeycomb sandwich panel formed by two aluminium plates and a honeycomb core structure. The 3D model of honeycomb sandwich panel is developed by the numerical model method by using MATLAB software. The dimensions of the thin panel plate are 76 mm × 221 mm × 1 mm. The number of fibers was observed in 50, 100, and 150 fibers number. Finite element model (FEM) for the aluminum honeycomb focus on the impact performance analysis. Software ANSYS Workbench Dynamic is used to perform impact testing. Hemisphere impactors with diameters of 30 mm and structural steel as material were chosen as hard mass hammer to simulate the impact test.
