Muppala Assistant professor Department of Mechanical engineering Marri Laxman Reddy Institute of Technology Hyderabad, India ABSTRACT Honeycomb sandwich panels can offer weight savings and specific strength requirements that are vital to today’s aerospace industry, in flooring to interior panels of aerospace vehicles. The main advantages of honeycomb panel are rigidity and shock, fatigue resistance, resistance to weather, chemicals and fire, recyclability, isolation. Aircraft floor panel is honeycomb structure bonded. Hex web honeycombs panel provides the ultimate high performance for the civil aircraft of the future. Edge coating of the honeycomb allows one to reduce panel weight without reducing the performance parameters that are required for different types of aircraft floor and interior panels. Honeycomb sandwich panels are used extensively for flooring in both military and commercial aircraft. Typically, commercial aircraft flooring is about 1cm thick and is made of glass or carbon fiber reinforced epoxy skins with a nomex honeycomb core. Commercial aircraft floors are designed to withstand high compression loads. The present dissertation deals with design and analysis of aluminum composite honeycomb structure. Catia and Ansys software’s are used for design and analysis of model respectively. In this project, a standard honeycomb cell size of 6.35mm has been considered. a honey comb panel 100mmx100mm has been designed using CATIA software and carried out structural analysis for designed model using ANSYS software for three different types of materials (aluminum alloy (Al-6061-T6, 6061-T651), titanium alloy (Ti-6-4), steel alloy (AISI 4130 steel)). Finally simulation results are discussed and reported. INTRODUCTION Honeycomb structure: Honeycomb structures are natural or man-made structures that have the geometry of a honeycomb to allow the minimization of the amount of used material to reach minimal weight and minimal material cost. The geometry of honeycomb structures can vary widely but the common feature of all such structures is an array of hollow cells formed between thin vertical walls. The cells are often columnar and hexagonal in shape. A honeycomb shaped structure provides a material with minimal density and relative high out-of-plane compression properties and out-of-plane shear properties.
