Shear Frame Test Fixture GZ S-100 / GZ S-100 HT

The shear test system GZ S-100 or GZ S-100 HT is an innovative test fixture for the determination of shear strength and shear modulus of fibre-reinforced plastics on the basis of a picture frame. The shear test system offers the possibility of a very precise determination of the shear properties of materials by means of shear tests and represents a significantly improved test method compared to ASTM D4255, ASTM D7078 and DIN EN ISO 14129.

Features & Benefits

  • Shear test system by means of a picture frame with unique possibility to determine the intralaminar shear properties in the specimen plane (in-plane shear test)
  • Material testing with pure shear stress condition
  • No free specimen edges and no notch effect due to flat specimen clamping
  • Available for testing in elevated temperature up to +150 °C (GZ S-100 HT)
  • Testing of material failure and buckling behaviour with test loads up to 100 kN
  • Specimen clamping by hydraulic cylinders for homogeneous clamping with clamping forces up to 120 kN
  • Testing of isotropic and anisotropic materials with specimen thicknesses of up to 10 mm
  • Operation in universal testing machines

Options

  • Operation with optional 700 bar hydraulic unit GZ HP-700 M
  • Clamping wedges with cross milling, longitudinal milling, transverse milling or diamond coating
  • Adapter for connection to all common electromechanical and servo-hydraulic universal testing machines

Standards

  • DIN SPEC 4885, “Fibre-reinforced plastic composites – Shear test method using a shear frame for the determination of the in-plane shear stress/shear strain response and shear modulus”, DIN, 2014
