Haufler Composites produces PEEK sheets using the press method for extremely demanding applications.
PEEK is a thermoplastic with high temperature resistance. In addition to the familiar properties of carbon fibre, such as high strength and stiffness, the PEEK matrix is characterised by extremely high resistance to chemicals, low wear and moisture absorption, excellent sliding properties and a maximum operating temperature of approx. 260 °C (depending on the application).
Haufler Composites produces carbon PEEK plates from fabrics with a fibre content ratio of approx. 50 % with a fibre orientation of 0°/90° or multidirectional fibre orientation of 0°/90°/+-45°.
Carbon PEEK plates from tape are produced with fibre orientation in any direction – e.g. unidirectional – and a fibre content ratio of approx. 60 %.
In contrast to carbon PEEK compounds, in which the thermoplastic is mixed with short carbon fibres, much higher mechanical characteristics are achieved by using endless carbon fibres.
In corrosive environments, CF-PEEK valves, bearings or slide rings in particular have a much longer service life and lower maintenance costs.

Our CF-PEEK sheets are used for components that are exposed to extreme conditions and have the following properties:

  • can be autoclaved
  • excellent chemical resistance
  • outstanding wear resistance
  • low friction coefficient
  • high abrasion resistance
  • no volatile components
