Polymers and Composites Technical Group (TG7) 

Polymers and composites are challenging the dominance traditional materials in a wide range of applications, mainly due to their potential advantages of low weight, good chemical resistance, and improved design flexibility. However, in many areas of industry there is a lack of knowledge regarding how these relative newcomers differ from traditional materials and how these differences influence the selection of polymers and composites for any application, and the design of joints between themselves and to other materials.

The aim of the Polymers and Composites technical group is to keep its members up-to-date with new developments in the areas of joining polymers and composites, testing and inspection of joints, assessment of fitness-for-purpose of polymer/composite structures, and national/international standards relating to these areas across a wide range of industries, from medical to oil and gas.

The group also serves to inform Members of the considerable challenges still facing the wider adoption of polymer and composite materials and the opportunities these create for those starting, or developing, a career in polymers and composites.

Meet the TG7 Chair

Dr Chris Worrall


Chris Worrall is a Consultant at TWI responsible for helping TWI Members solve their problems involving polymer and composites materials and their joints. His 35 years of composites expertise covers; composite-metal joining, thermoplastic composite welding, microstructure characterisation, testing (mechanical, high rate, fire, electromagnetic), finite element analysis (FEA) and design of composite structures, digital image correlation, and manufacturing technology for composite materials.

Chris holds a PhD in the impact of composite sandwich structures in addition to a BSc in metallurgy and materials science, and spent 10 years working in Japan before returning to the UK and joining TWI in 2010.
