WACOSIT® pultruded profiles
Construction and characteristics WACOSIT® profiles are made using the “pultrusion” process. The fibres used to reinforce the profiles are injected with artificial resin and then gradually cured in a heated mould.
WACOSIT® profiles can be reinforced with glass fibre, carbon fibre, aramid fibre and basalt fibre. There are various different specifications for each of these different types of fibre. The most commonly used glass fibres are E-glass fibres, but profiles can also be made with R, S, or T-glass fibres, which have enhanced mechanical properties.
The resin matrix includes epoxy, vinylester, polyester and acrylic resin.
At Ernst Kühne Kunststoffwerk, we have a choice of over 5,000 tools for WACOSIT® profiles. You can find dimensions for most of these tools in our latest WACOSIT® Profile Catalogue. As you would expect, we can also deliver bespoke profiles according to your requirements and blueprints whenever you need them.
Why choose glass-fibre-reinforced (GFR) profiles?
We produce pultruded, glass-fibre-reinforced profiles under the WACOSIT® brand.
Why choose carbon-fibre-reinforced (CFRP) profiles?
Carbon-fibre reinforced profiles are widely used in the automotive and aerospace industries.
Pull-winding is the perfect complement to our pultrusion technology. Integrated inline winding technology gives our anisotropic pultruded profiles outstanding transverse rigidity. Pull-winding is particularly suitable for round and hollow profiles. The difference between pull-winding and standard pultrusion lies in the way the transverse glass fibres are arranged. In the standard pultrusion process, meshes and weaves tend to be added to the UD fibres.
With pull-winding, on the other hand, the reinforcing fibres are wound over a rotating mandrel using endless glass fibre strands. This double-winding technique gives the resulting product excellent compressive strength and rigidity.
We manufacture fibre-reinforced filament-wound parts using various combinations of materials. The precise specification is tailored to your requirements and how the product will be used.
WACOSIT® wound parts are made using glass-, carbon- or aramid-fibre rovings impregnated with epoxy, vinylester or polyester.
Due to the resins used WACOSIT® wound parts are suitable for appliances in insulation classes F to H.
WACOSIT® wound parts can maintain their dimensional stability at temperatures up to 240°C.
We will be happy to design bespoke winding components for more demanding thermal requirements.
