Damage Tolerance of Naval Sandwich Panels

Abstract: This paper is a review of activities concerning various damage tolerance modelling and testing aspects of sandwich panels for typical Naval applications. It starts with a review of testing methods for primarily core materials and how to extract properties and data required for damage tolerance assessment. Next some typical damage types are defined and how they are modelled with the aim of predicting their effect on load bearing capacity. The paper then describes in brief how such models can used in the context… Show more

“…Carbon-fibre reinforced composite (CFRC) structures are widely used in the aerospace, automotive and marine industries, due to their effective fire and corrosion resistance, acoustic insulation, high stiffness/weight ratios, construction flexibilities and lightweight advantages [1,2,3,4]. In several construction requirements, two or more such composite laminates are bonded with epoxy adhesives and debonds can occur at such adhesive interfaces, due to temperature fluctuations, improper handling, impact, fatigue and ageing [5,6,7,8,9]. Hence, fast and effective nondestructive evaluation and structural health monitoring (SHM) strategies are required to detect such hidden debonds under variable ambient temperature conditions, in order to avoid catastrophic failures while the structure is in-service [9,10].…”

“…Ultrasonic guided wave propagation-based SHM strategies have proven their potential to effectively identify hidden defects in complex layered materials [7,8,9,10,11,12,13,14,15]. As the piezoelectric transducer (PZT)-induced guided wave propagation-based SHM techniques offer long-distance inspection potential due to the penetration capacity into different layers in the composites with less attenuation [12,13,14,15].…”

“…Since fiber-reinforced composite structures offer superior strength, higher stiffness, lighter weight and greater durability [1], they are increasingly being used for primary aircraft components traditionally made of metallic materials. However, despite their good properties, composite airframe structures are more sensitive to impact damage, which can cause disbonding, delamination and internal crushing.…”
