Description
Summary:Honey comb means the concise and orderly pattern of comb is a symbol for structure, order, utility and strength. Honeycomb sandwich panels construction is based on top and bottom layer made up of carbon and glass reinforced fibers which make the panel strengthen in tension whereas mid layer/core is made up of aluminium which is responsible to transfer the tension and shear load between top and bottom layer. Aluminium core possess high shear and crushing strength along thickness of the core. Composites panels are rich in high strength to weight ratio; top and bottom layers are separated through by core; which will increases the inertia of the section results in higher flexural/bending stiffness of the panel. Due to higher stiffness of honeycomb structure it finds the industrial application widely in Automobile, Aerospace, Locomotive and space structures. sandwich panel Compressive strength depends on foil thickness of honeycomb core. Present study focuses on the investigation of effect of Honeycomb structure geometrical parameters variation on its fundamental natural frequency. Detailed structural behavior of the Honeycomb structure is studied due to the variation of geometrical properties like change in no of cells along the span length (6, 7, 8 & 9), variation in cells width (W), variation in cells height (h) and variation in cells shape (Hexagon, Quad & Tubular). In present study Honeycomb structure is made up of glass & carbon fiber unidirectional as face plates while aluminum 5052 as honeycomb core material; further FE modelling and analysis is performed through Patran & Nastran. This study captures the salient features on the effect of variation of geometrical parameters on elastic deformable modes of Honeycomb structure.
