ILSS Test Fixture GZ IL-10
The short beam shear test for the determination of apparent interlaminar shear strength (ILSS) is a modified 3-point bending test. The span length of the fixture is small as compared to the specimen’s thickness which induces shear stress to the specimen. The geometry of the specimen is a short beam of thermoplastics or thermosettings continuously reinforced by fibres in 0° or 0°/90°-direction. The standard defines apparent interlaminar shear strength as “maximum shear stress calculated at half thickness of specimen at the moment of first failure.”
Features & Benefits
- Compact design allows testing forces up to 10 kN
- Exchangable test fixture modules for quick and easy adaption of the testing device to various testing standards
- Precise alignment of the specimen due to lateral guiding and adjustment gauge
- Stainless steel design of all components for use in climate chambers (-60…+150 °C)
Options
- Support inserts for different standards
- Adapter for connection to all common electromechanical and servo-hydraulic universal testing machines
