Effect of Cell Size Material on the Mechanical Properties of Honeycomb Core Structure

Nurashikin Sawal, Abdul Basit Mohd Nazri, Hazizan Md Akil

Abstract: A study on the effect of cell size material on the mechanical properties of honeycomb core structure was performed with different materials used, Al 6061, polypropylene and polystyrene. Drop-weight impact test and compression test on honeycomb structure core have been performed with impact test showed the results of maximum force and value of energy while the compression yield the stress-strain curve as well as failure mechanism in the structure. The experimental result shows that impact force increased with the increasing value of energy. Al 6061 honeycomb structure showed the most deformation formed compared to the thermoplastic core. Experimental compression test was conducted to analyze the mechanical behaviour of honeycomb structure core under compressive loading and from the observation the core started to buckle at the edge due to the stress loading. Al 6061 core shows permanent buckling while thermoplastic rebound back after certain amount of time.
