Through Thickness Tensile Testing of Hybrid Structures

Fraser Jeavons


Composite materials are an integral part of the aeronautical industry due to their low density and high strength physical characteristics. These materials are adhesively bonded to metallic plates regularly. With delamination being discovered within these joints there is growing interest into the different strength parameters associated in the wing system. The aim of this research paper is to investigate the through thickness tensile strength of a composite material. This research endeavors to develop a new testing method that can be implemented to test in specimens taken from in service aircrafts. Prior to possible implementation the accuracy of the testing method was required to be investigated. This paper will outline the materials, specimen design, method and analysis involved when calculating the through thickness tensile properties of hybrid materials.
