Self healing technology pull through

Circular Composites, in collaboration with the National Composites Centre (NCC) and the University of Bristol, is proud to announce a major advance in sustainable composite repair with the launch of our self-healing vitrimer interface technology. This innovation addresses one of the composite industry’s long-standing challenges: enabling reliable, repeatable, and scalable repair of high-performance composite structures—directly in the field. The NCC has published an article detailing the research journey of our founder, Joe Soltan, and highlighting the real-world significance of this cutting-edge technology. The full article is available here: https://www.nccuk.com/news/tpt-healable-interfaces At Circular Composites, we are driven by a mission to deliver a truly circular economy for composites. By combining advanced vitrimer chemistry with fusion manufacturing techniques, we have developed a repair process that eliminates the need for adhesives or component replacement—significantly extending the lifespan of composite parts and reducing environmental waste. “From wind turbine blades to aerospace components, composite structures are vital to modern infrastructure—but sustainable repair has remained a critical gap,” said Joe Soltan, CEO of Circular Composites. “Our self-healing vitrimer interfaces change that. This is a transformative step for durability, reparability, and sustainability. We are proud to be part of such a strong R&D ecosystem. The NCC’s Technology Pull-Through Programme was instrumental in advancing the maturity of this technology.” The breakthrough was demonstrated on a T-stiffened composite structure representing part of a wind turbine blade. After inducing complete structural failure, the team successfully restored the interface using induction heating—re-mobilising the vitrimer matrix and proving the system’s efficacy for real-world deployment. This innovation directly supports manufacturers and asset owners in achieving net-zero targets by reducing material waste and improving in-service maintenance. It also reflects Circular Composites’ long-term commitment to designing composite solutions with repairability, reuse, and recyclability embedded from the outset.
