With the launch of 12 new composite fiber splicers, Airbond (Pontypool, U.K.) has doubled its product range (with models focused on waste recovery) and extended the limit of fiber splicing limits tenfold to enable splicing of more challenging materials and higher concentrations. Lighter, simpler and more tolerant of rough treatment, Airbond’s patented yarn splicers now offer a wider range of applications with improved ergonomics and cover all fibers, including polypropylene (PP), nylon, glass and carbon fiber and other synthetics.
Some models are now capable of splicing super-large yarns up to 16,000 Tex, compared to conventional 1,200, 2,400 and 4,800 Tex yarns. These splicers have the option of coming with a flow control system which supplies variable-pressure air to the blast chamber, while keeping the main factory line pressure unchanged. They can be used to deliver distinct, innovative techniques for joining brittle yarns such as glass and carbon fiber, and joining inherently strong aramid fibers.
A fixed-position splicer model has been added and enhanced for efficient waste yarn recovery. This can be used for “bit-winding” — a process where full-weight bobbins are created by repeatedly winding “shorts,” and are then spliced together several times until a full weight is reached. This particular model can be bolted to a simple bit-winding machine and is designed for frequently repeated splicing over long time periods.
The wrapping splicer model for monofilaments and fibrillated fibers can be applied to monofilaments, braided yarn, heavily-sized or coated yarn and high-twist yarn, which are traditionally problematic materials. Two yarn ends are overlapped, and a fine auxiliary yarn is tightly wrapped around them and bound to produce a joint of high strength. The jointing method has a patent pending.
All Airbond yarn splicers, which includes a five-year guarantee in normal usage, have also been revised with a 3D-printed body for higher reliability.
Further, according to Graham Waters, managing director of Airbond, its splicer technology offers the composites industry a robust method suitable for composite companies that work in fiber manipulation, with reduced waste and time and cost reduction. Airbond splicers can be manufactured to order, with fast quick turnaround times.
Commercial production of recycled carbon fiber currently outpaces applications for it, but materials characterization and new technology demonstrations promise to close the gap.
Fast-reacting resins and speedier processes are making economical volume manufacturing possible.
