Cevotec reports that cevoTape is individually manufactured and tailored to major automated fibre placement (AFP) processes, offering a new option for series production at reasonable economics.
“Automated fibre placement processes require superior tape quality to minimise downtime and ensure high precision and repeatability,” explains Felix Michl, CTO of Cevotec.
As the right fibre is crucial for the quality of a composite part, Cevotec developed cevoTape, a dry fibre spread tow made from high-quality carbon fibre rovings with a copolyamide adhesive binder.
“With cevoTape we offer an alternative to expensive aeronautic-certified tapes,” reports Thorsten Groene, Managing Director of Cevotec. “It is suited for non-aeronautic applications, e.g. the automotive industry. We’ve already received solid interest from manufacturers of AFP/ATL equipment who are looking for tape material for their customers. Initial tests of cevoTape with their robotic layup heads were performed successfully.”
Cevotec processes its own unidirectional carbon fibre tape (spread tow) in the SAMBA Series Fibre Patch Placement systems. cevoTape also meets the requirements of other automated fibre placement processes like AFP and ATL to create high quality laminates and can be used for a variety of different applications. The tape width can be customised within minimal tolerances and thanks to an integrated quality monitoring, it features a homogeneous filament distribution. The single-sided, uniformly distributed PA binder is activated at temperatures of 90-160°C. Thus, cevoTape can be easily fixed during processing, and stored at room temperature.
“Customers may approach us with roving material of their choice and have us manufacture their individual tape,” says Michl. “We process any high-quality fibre.”
Alternatively, there are pre-configured tapes using Tenax-E HTS45 fibres in stock, featuring 20 mm or 30 mm width and 80-107 gsm areal weight, separated with paper film, stored on Häfner spools (250 m, custom lengths on request).
Besides compatibility to the SAMBA Series manufacturing systems, Cevotec guarantees highest quality for all major placement processes as well as the dimensional tolerance of the tape that allows manufacturers to attain the high placement and operating precision they desire.
“Such a tape quality achieves outstanding results in production processes and allows the economic application of AFP/ATL processes in non-aeronautic applications,” concludes Michl.
