Rockwood Composites says that it used composites to successfully assemble the central core for the UK’s newest fusion device, Tokamak Energy’s ST40.

This involved the very precise application of a glass-fibre/Kapton/glass-fibre insulation layer to each of the core elements. The whole assembly was then bonded together with accurate control of the bond line thickness. Tokamak Energy is an Oxfordshire-based company that grew out of the Culham Centre for Fusion Energy. The business was established in 2009 to design and develop compact fusion power plants. Tokamak Energy’s aim is to put fusion power into the grid by 2030.
