Hydraulic ASTMD6641

Hydraulically Actuated High-Force Combined Loading Compression Test Fixture (ASTM D6641)

The hydraulic actuated test fixture is designed to provide convenience, consistency and efficiency in

conducting tests according to ASTM D6641/D6641M to understand the compressive properties of polymer matrix composite materials.

Compressive forces are applied to both ends of the test fixture, simultaneously generating combined shear and end loading to the specimen. Thanks to the clamping blocks that prevent buckling and end crushing, the fixture can be used to test both tabbed and untabbed specimens.

Design Features

● Utilizing hydraulic compression to deliver strong, evenly distributed, and consistent clamping forces on the specimen for tests up to

100kN compressive load

● Fast specimen installation without the hassle of tightening bolts

● Improved result consistency by reducing variations in specimen installation

● Four-guiding-rod design allows an unobstructed view of the stress region for use of video extensometers

● Works with specimens of 110mm or 140mm in length
