Jim Thomason is an acknowledged world expert in the research and development of glass fibre-reinforced composites. ScholarGPS recently awarded him #1 Highly Ranked Scholar status in the area of Glass Fibre. He has 25 years of industry experience, at Shell Chemicals and Owens Corning Fibreglass, leading fibre and composite product development programmes involving extensive fundamental research of glass fibre sizings, interfaces and composite structure–property relationships. In 2007, he was appointed Professor of Composite Materials at the University of Strathclyde, where he established the Advanced Composites Group, whose mission is to generate industrially relevant fundamental understanding of reinforced polymer composites. His research group is highly active in the field of structure–(re)processing–performance relationships in composites, with a strong focus on sizings and interfaces, and the recycling and reuse of glass fibres recycled from end-of-life composites.
