Karl Mayer, Germany’s leading textile machinery firm, successfully participated in the recently held JEC World tradefair, from March 6 to 8, 2018, in Paris, France. The company’s well-attended information stand on the topic of multi-axial warp knitting machines and fibre spreading units in the composites expo attracted a lot of international visitors.
Visitors came all over from Europe, China, US, India, and Turkey. The discussions not only confirmed already known trends, but they also provided new ideas.
Numerous conversations during the exhibition were about lightweight solutions with automated production, high reproducibility, and well-balanced price-performance ratio. Carbon fibres are still too expensive, and they are only used if the performance requirements do not allow any other option. This was clearly demonstrated by the specific demands for aerospace applications. But even here cost optimisation is needed, focusing on the targeted use of dry carbon fibre layer structures as alternative to the cost-intensive prepregs.
For glass processing, Karl Mayer showed the COP MAX 4. On this multi-axial warp knitting machine, it is possible to produce dry glass layers which are not only in demand by the wind energy market, but also by the automotive industry.
Another approach to a cost-optimised manufacture of composites was presented with the “Vario Laying” procedure. This innovative method ensures a mechanical and load path-oriented positioning of the carbon fibres just during the production of dry glass layers.
The company also displayed the UD 700 fibre spreading unit in the expo. Alexander Wegner from Karl Mayer’s exhibition team and senior manager application technology, explained that the use of glass is also becoming increasingly interesting for another trend area of the composite industry; namely for thermoplastic applications. In the overall production process, thermoplastic composites made from glass layers are cheaper than duroplastic composites, but for their manufacture they require a special know-how, in particular during spreading. Nevertheless, with its fibre spreading unit UD 700, Karl Mayer is well positioned for the future. (GK)
