Oerlikon Barmag at JEC 2015

Chemnitz, Remscheid, 04 February 2015 – Different components for the production of composite materials are the focus of the presentation by Oerlikon Barmag at this year's JEC in Paris. From 10 to 12 March, at the trade fair for the composite materials industry, the machine and plant engineering company will be providing information about its latest and established products in the areas of pump construction and on winders for special yarns (stand number: P66 / Hall 7.2).

Shaping the future with modern materials

Innovative technologies for innovative fibers
For a large variety of mixing and dosing tasks in fiber and plastics processing, Oerlikon Barmag offers the solutions, which actually enable economical production. Its spinning pumps known for their precision are often used for spinning the composite base materials polyacrylonitrile (PAN) and aramid. A large share of today's common high-performance carbon fibers are now made of polyacrylonitrile. An essential feature of these fibers is their high tensile strength despite their very low weight. This modern material is in use in a variety of industries today, including the aerospace industry, medical technology, wind energy, the automotive industry, etc. High-strength multifilament yarn made of polypropylene (10g/den) is also the component of preference in composite materials. An extrusion plant for the production of these special fibers is part of the product portfolio of Oerlikon Barmag.

With WinTrax, Oerlikon Barmag has also developed a winder specifically for use in the production of carbon fibers. The winder – which has been designed both for one- and two-cop systems - combines economically efficient production of highest-quality carbon fibers with perfect package build-up and identical running length. Both small and large package weights up to 20 kg can be realised. The higher package weights reduce set-up times, reducing the cost of composite production considerably. The identical running length of all packages trims waste to virtually zero percent.

Special yarns of aramids are characterized by their extremely high tenacity, high breaking elongation, good vibration absorption and resistance to acids and alkalis. They are also very heat- and fire-resistant. Not only are these yarns are used in special applications, but they also call for very special processing. With WinOro, the automatic monofilament or two-ply precision winder, Oerlikon Barmag has the perfect winder for these high-performance fibers. Gentle yarn treatment and perfect package build-up, energy efficiency and a high degree of cost effectiveness make it the perfect choice for demanding special yarns.

When casting the required composite matrix of composite materials (e.g. resin + hardener), on the other hand, high-precision metering pumps by Oerlikon Barmag are the instrument of choice. They are characterized not only by exact metering but also by their durability, ease of maintenance and operability
