3-/4-Point Alternating Flexural Test

3-/4-Point flexural test fixture GZ B-50

The reversed loading flexural test fixture allows for the static and dynamic characterization of the flexural properties of fiber-reinforced plastic materials for both 3-point and 4-point bending tests.

The test fixture is suitable for testing a wide range of fiber-reinforced plastics with short, long and continuous fibers with thermoplastic or thermosetting matrices and unidirectional layers or multi-layer laminates (sandwich laminates).

Features

  • Design allows high loads up to 50 kN in static and dynamic loading
  • Quick and easy changeover between 3-and 4-point
  • High number of cycles with low maintenance possible thanks to needle roller bearings placed in each support frame
  • No lateral movement of specimen during dynamic testing due to vertical and axial constrains
  • Test fixture can be used to construct S-N curves under fully reversed loading (R = -1) and many more
  • Constant- and variable amplitude fatigue tests 
  • Stainless steel design of all components for use in climate chambers (-60 to +150°C)

The test fixture can be used to conduct flexural tests according to the following standards:

  • DIN EN ISO 14125:1998-06
  • DIN EN ISO 178:2003-06
  • DIN EN 2562:1997-05
  • DIN EN 2746:1998-10
  • ASTM D 790-10
  • ASTM D 7264-07
  • ASTM D 7774-12
