Product Description

Sample Size

Tabbed specimens to ASTM D 3410. Max length 155mm, max width 13mm, max thickness 8mm over tabs.


Sample Type

GRP, CFRP, and similar fibre reinforced resin composites.



10 kg.



Installation fixture and jaws are included with the fixture. Variations on jaw size and guide rod length can be accommodated.



Designed to take a restricted sample size, both in width and thickness compared to the full range fixture ST55, this fixture is both lighter and cheaper. It complies with the requirements of ASTM D 3410 for testing composite materials in compression. The top and bottom halves of the fixture are guided on precision linear bearings to ensure accurate alignment. Samples are first loaded in to an alignment jig with the jaws to ensure the sample is square to the axis of the jaw faces. The sample/jaw face assembly is then loaded in to the fixture and the two halves brought together to perform the test.


Jaw faces are hardened to approximately 60HRC and have a fine tooth pattern on the gripping surface. Alternative hard particle faces can be supplied if required.


Extended guide rods may be fitted if samples with a gauge length longer than 25mm are to be tested.
