Experimental Investigation on Honeycomb Composite Materials

Honeycomb structures are often natural or artificial assemblies, which have the similar geometrical shape of a honeycomb and are used to get the expected strength by minimize the amount of used material, reduce the weight and cost of the materials. The advantages of honeycomb sandwich structures when compared to conventional structures are that it provides: very low weight, production cost savings, durability and high stiffness. Acrylic Honeycomb structures are made-up of unique core material that offers advantages such as good impact strength, transparency, resistance to breakage, elasticity, good weather ability, good heat resistance,excellent dimensional stability.In this paper Acrylic honeycomb sheet structure is used as a core material along with carbon fiber reinforced polymers (CFRP) and glass fiber reinforced polymers (GFRP) as face sheets for fabricating the honeycomb sandwich composite and evaluate the mechanical properties like tensile strength, flexural strength, impact strength and hardness. Scanning electron microscope (SEM) analysis also conducted for checking the good bonding of the honeycomb structure.
