Abstract

This study on honeycomb structure is done to find the best materials for honeycomb structure that have the outstanding properties. Firstly the previous researches about honeycomb properties and materials are studied. lbis is to get a better knowledge on this study. Besides that the product that uses this sandwich structures are identified. This study of honeycomb is for the usage in the aircraft industry. It is studied in which part of the aircraft is the sandwich structure applied. lbis study to frnd the best material for lightweight application will use 3 types of material. Among the three materials are aluminium cans, aluminium sheet and straw. Before carrying out the study the physical properties of those materials are studied. The honeycomb structures are built using the materials. The composition of each material had been planned first. After each model has been constructed it will be tested. The testing is done according to ASTM standard (American Society for Testing and Materials). There were 3 test conducted which is the bending test, compression test, and tensile test. For the tensile test the mechanical properties obtained are yield strength, tensile strength and modulus of elasticity. For the bending test the mechanical properties obtained are flexural modulus and flexural yield strength. Lastly for the compression test the mechanical properties obtained are compressive strength and modulus of compression. Between the two materials which are aluminium can and straw it is proved that the aluminium can is better than the straw. lbis is due to the good results of compressive, yield and tensile strength.
