Fabrication and testing of various sandwich composites

Abstract

Industries like aerospace, civil construction and automation uses the sandwich composites widely due to their high strength at low weight. The face sheets and core of the composites play a vital role in the properties of composites. The mechanical properties of these types of structures depend on the application and under various environmental conditions. Most of the sandwich composites will fail due to debonding and core crushing. In this research, three types of sandwich structures like bamboo, V-Board and metal type are tested and characterized for mechanical properties. The sandwich composites are tested by 3-point bending and UTM test to identify several mechanical properties like tensile strength, Young’s modulus, fracture, etc. The results show that the bamboo type sandwich composites have high strength and low weight as compared to other composites.
