Mechanical Behaviour of Composite Corrugate Core Sandwich Panels

Abstract

Aluminium sandwich construction has been recognized as of promising concept for structural design of light weight transportation systems such as aircraft high speed trains and fast ships. The aim of the present study is to investigate strength characteristics of aluminium sandwich panels with aluminium corrugated core experimentally. A series of crushing and bending test is carried out on corrugated core sandwich panel. The comparison of results is done based on the parameters viz. no of layers and patterns of perforated sheets. The structural failure characteristics of corrugated core sandwich panels are discussed. The test data developed are documented.
