Designing with composite materials. 48th John Player Memorial Lecture

20 March 2013

Fibre Reinforced Polymer composites (FRPs) are now widely used in many applications including aircraft, yachts, wind turbines, motor vehicles, chemical process plant, sporting goods and a wide range of military equipment. They are an extremely broad and versatile class of materials, encompassing a wide range of fibre and matrix combinations that provide a multiplicity of component design and manufacturing options. FRPs are inherently more complex that metals, being heterogeneous in construction and anisotropic in behaviour.

In moving from the metals world to the FRP world, a structural designer is faced with many more variables and the need for an additional set of design methods. It is, perhaps, self evident that such methods must be accurate and valid in order to support the development of components which are timely, cost effective and competitive in performance.

Over the last 19 years, the authors have been organizing and coordinating a series of international activities (known as the World Wide Failure Exercises) to improve the foundation on which the design theories for FRPs are based.

The purpose of this lecture is to review the progress achieved to date, the work currently underway and the remaining challenges towards fulfilling these objectives.

Professor Mike Hinton

Mike is currently the Technology Director at the National Composites Centre (NCC), one of seven Government sponsored high value manufacturing catapult centres.

He has more than 40 years of experience of working on programmes aimed at gaining a fundamental understanding of composite materials and using that knowledge to develop practical hardware. His work includes theoretical and experimental investigations into the response of polymer composite structures when subjected to a wide variety of loading conditions encompassing multi-axial, impact, high strain rate and thermal events. Mike has developed a number of components for volume production where composites have been utilised to give innovative solutions.

He has collaborated extensively with research organisations in the UK and internationally and is a visiting professor at Nottingham University.


Dr Sam Kaddour

Sam is a QinetiQ Fellow with a broad academic and industrial experience in the design of lightweight structures, spanning more than 25 years. He possesses an in-depth understanding of the mechanics of composite materials and composite structures. His work includes modelling failure and improvement of validated computer codes for composites together with developing multi-axial rigs for testing composites tubes under a wide spectrum of loading. He obtained his PhD in 1992 from the University of Manchester Institute of Science and Technology (UMIST) and joined QinetiQ in 1999. Sam has worked on a wide variety of projects sponsored by the UK MoD, aircraft and offshore industries. He has published and co-authored a number of articles in scientific journals.
