Celanese Compression Test Fixture

Celanese Compression Test Device GZ C-20

Celanese compression testing device is used for determination of characteristic material values under compression load.

With the testing device, short, long or continuous fibre reinforced thermosets or thermoplastics can be testet as well as unidirectional layers or fabrics, multi-layer structures and sandwich laminates.

The device is used to prevent buckling of the fibre reinforced material. For a specimen length of 110 mm the free lenght is only 10 mm. Strain gauges are applied on both sides of the center area of the specimen to determin (negative) compression extension and bending. According to a principle relying on self-amplification, the clampings of the testing device switch the machines’s axial forces into a transverse force to grip the specimen.

Characteristics

  • Sturdy compression device for static forces up to 20 kN
  • Design allows switchover between shear loading and end loading of testing forces
  • Changeable clampings for different materials and fibre orientations
  • Easy cable passage for strain gauge
  • Stainless steel design of all components for use in climate chambers (-60 to +150°C)

Accessoires

  • Clampings cross-, lenghtwise-, transverse- milled or diamond coatet
  • Angle compensation element
  • Adapter to all current electro mechanical and servo hydraulical testing machines
