We are proud to announce that a fifth patent has been granted for a novel joining technology co-developed by TWI for joining composite pipes.
Working under the umbrella of the Non-Metallic Innovation Centre (NIC), TWI invented a novel, corrosion-free, reinforced composite pipe connection system, marking another milestone in the NIC’s commitment to advancing composite joining solutions. The joining concept originated from the successful development of a composite welding process in a 2019 project funded through TWI’s Core Research Programme (CRP), and draws on TWI’s 40-year heritage of induction welding thermoplastic composites.
This new, cutting-edge process is designed to improve the reliability, precision, and sustainability of composite pipe joining. The advantages of two different welding processes are combined to join dissimilar non-metallic materials through a range of approaches. This fifth granted patent reflects our continued focus on innovation, IP protection, and delivering competitive advantages to our Industrial Member companies, while the newly granted patent reinforces our position at the forefront of non-metallic technologies.
This milestone adds to a growing portfolio of intellectual property developed by TWI, supporting our Industrial Members in protecting their research and development.
Based at TWI’s headquarters near Cambridge, the Non-Metallic Innovation Centre (NIC) opened in September 2019 in order to advance the use of non-metallic materials for industrial applications. This is achieved through research programmes with partners from academic institutions, research centres, composites materials manufacturers, and oil and gas companies.
You can find out more about the NIC on the dedicated website, here.
