Technical Group Webinar


Who should attend? 

Designers, materials engineers, fabrication supervisors, quality control personnel, NDT engineers, anyone curious about composites and adhesives.

What will you learn? 

Most manufacturing standards and requirements for freedom from flaws are based on the needs of the metals fabrication sector. These focus on joints, as the materials themselves are usually controlled/inspected at source, and the types of flaw are specific to welding.

Where polymers, composites or a combination of metals and polymeric materials are used, a different approach is needed, both for the areas to be controlled/inspected and the types of flaws sought. This applies at the composite manufacturing stage, joining, and for in-service inspections.

This event will highlight the types of flaws encountered in composite manufacture, including joining, and present some strategies for detecting/controlling these.

Expert from industry will be presenting on a range of topics:

  • Dr Ewen Kellar, Consultant, TWI Ltd on The Source of Defects in Adhesively Bonded Joints 
  • Dr Sadik Omairey, Senior Research Fellow, Brunel Composites Centre, Brunel University London on Stochastic Simulation of Defects in Polymeric Materials 
  • Calum Hoyle, Team Manager, NRT, TWI Ltd on Introduction to TWI and the NRT section
  • Pete Sheppard, Senior Naval Architect, RNLI on RNLI’s use of NDT in testing and evaluating lifeboats structures

Ewen Kellar


The source of defects in adhesively bonded joints

Ewen has worked in the field of adhesion and adhesive technology for over 30 years, predominantly at TWI. During that time he has worked in almost every industry sector and with a vast array of applications including those in motorsports, medicine, automotive, shipping, aircraft, electronics, trains and even clothing and footwear. He has supported the Bloodhound supersonic car development, provided expert input into television documentaries and quiz shows and even appeared on the One Show on BBC1. He is the author of over thirty publications, a chapter contributor in three books and has presented at many conferences around the world.

Pete Sheppard

Royal National Lifeboat Institution (RNLI) 

Presentation: RNLI’s use of NDT in testing and evaluating lifeboats structures

Pete has spent 30 years working as a laminator, boat builder, project manager and naval architect as well as having been involved in the marine industry at many levels. 

He has been responsible for the structural design and build of prototype lifeboats, the production of various classes and many repairs of in-service boats. Specifying materials, processes and testing and overseeing repairs in internal and external yards. 

Sadik Omairey

Brunel Composites Centre

Stochastic Simulation of Defects in Polymeric Materials 

Dr Sadik Omairey have a record of accomplishment in developing numerical-based, reliability methods that are capable of modelling composites defects and uncertainties. These methods address challenges related with modelling the material in a multi-scale manner, and the computational time needed to analyse these simulation.

Calum Hoyle


Introduction to TWI and the NRT section

Calum's relevant expertise includes: NDT (UT, PAUT Advanced UT, Microwave, tap testing), robotics
