CHESHIRE, England — July 17, 2024 — Composites technology company Cygnet Texkimp has supplied a multi-mode filament winding cell to TWI’s Materials Integrity Centre in Middlesbrough, England.
The technology will be used to develop, validate and commercialize new composite materials and parts, including high-performance pressure vessels and pipes for the aerospace, nuclear and hydrogen markets.
TWI is a membership-based global research and technology organization offering R&D support and engineering, materials and joining technologies at 18 sites worldwide, delivered by more than 800 scientists, engineers, consultants and support staff. Its Materials Integrity Centre is a state-of-the-art laboratory and world-leading test facility part funded by the European Regional Development Fund to provide specialist materials and engineering support to businesses in the North East of England.
The cell delivered by Cygnet Texkimp consists of a filament winding machine, driven fiber unwinding creel and pneumatic mandrel extraction technology. It is designed to run in a number of modes and can be modified to accommodate different resins and materials, with an adaptable wet-out system and wet winding capability to trial and optimize new resin formulations.
The machine can wind four tows simultaneously and each tow has its own tension control unit and dancer arm to regulate tension. This, coupled with a bespoke fiber handling and delivery system, enables accurate winding at higher tensions and speeds. The machine developed for TWI is currently capable of winding dry fibers and towpregs at tensions in excess of 100 Newtons, but with simple modifications, and depending on the fiber being wound, can be engineered to produce much higher tension in the region of 200 to 300 Newtons.
Mihalis Kazilas, Business Group manager of TWI’s Materials Performance and Integrity Group said: “The new centre combines the industrial expertise of TWI in the area of non-metallics testing and evaluation with the academic excellence of Teesside University in net-zero technologies. Together, TWI and Teesside University will support local businesses and enterprises in the development of new products and services that will contribute to the growth objectives of the Tees Valley Social Economic Plan.”
Amir Khamsehnezhad, Section manager at TWI’s Polymers & Composite Services Section, said: “The filament winder is a key piece of equipment that will help TWI deliver research and manufacturing projects on composite pipes and tanks. The equipment is already playing a role as part of a bid for the European Space Agency (ESA) to develop SMART manufacturing technology.”
Gareth Davies, International sales manager at Cygnet Texkimp, explains how the machine’s engineering makes it ideal for TWI’s R&D programmes: “A crucial feature of this highly versatile, multi-mode winding cell is the ease with which it can be modified and customised by TWI, giving the organization and its partners a very flexible resource to carry out effective product development and optimization.
“As with all our machines, the way the fibers are handled and guided through the cell is critical to the quality and performance of the end product. Because this machine has been designed to look after the fibers throughout the process, TWI and its partners can achieve higher production speeds and fiber tensions, which in turn leads to lighter, thinner parts.”
