Innovative Tooling
End-Effector Development and Industrialisation for Welding of Thermoplastic Components


The next generation of large passenger aircraft will make extensive use of thermoplastic composites, which could replace thermoset composites and metals in many areas of aircraft construction. Thermoplastic composites can be lighter in weight even than thermoset composites, but the key advantage is that they can be joined together using welding processes. This has the potential to eliminate many of the hundreds of thousands of fasteners in an aircraft, improving reliability and reducing assembly costs.

Taking the full advantage of thermoplastic composites weldability will require the development of innovative new approaches to tooling and automation to eliminate or reduce fixed tooling costs, which can account for more than one-third of non-recurring costs.

TCTool project will develop innovative new end-effectors for jigless assembly of thermoplastic composite fuselage structures, and new adaptive tooling for the welding of thermoplastic fuselage skin to stringers and frames. This will allow highly automated assembly of these complex structures with tooling that can be re-configured digitally and reused.


The project will also deliver simulation tools and perform manufacturing simulations to quantify variations in assembly, risk of defects, and optimise the process to achieve cost-effective zero-defects assembly.

Brunel University London

Brunel University London has been highly successful in creating industrial innovation research resources, including the Brunel Composites Innovation Centre (BCC). BCC sits between the knowledge base and industry, supporting partners in the industry to transfer academic research into industrial application. BCC specialises in novel composites processing and joining technologies, applied to industrial environments.

London South Bank University Innovation Centre

The London South Bank Innovation Centres (LSBIC and PolyMERIC) were both established at Granta Park, Great Abington, Cambridge, UK by London South Bank University (LSBU) as a long strategic partnership. LSBIC was established to research and develop automation for inspection, maintenance and repair. The aim is to take award-winning robot prototypes developed by the university towards commercialisation by locating the centre in an industrial environment. PolyMERIC is mainly focused on advanced/smart polymers and reinforced thermoplastics, joining of thermoplastics and non-destructive testing techniques that can be utilised to be used with these materials. The centre researches into and develops new polymer materials, testing and inspection methodologies in harsh environments, in the TRL1-6 region.
