LBTA-229 Geotextile and Geomembrane Puncture Test Fixture

Description

Product Introduction:

It is used to determine the puncture resistance of geotextiles, specifically the maximum force measured during the process in which a plunger applies pressure to the specimen until it ruptures. This method is suitable for geotextiles, geomembranes, and their composite products, but not for materials with apertures larger than 10 mm.
It complies with the requirements of JTG E50, “Test Procedures for Geosynthetics in Highway Engineering,” and GB/T 19978, “Determination of Puncture Resistance of Geotextiles and Related Products.”

Technical Specifications:

Name	Geotextile and geomembrane puncture test fixture
Material	45# steel
Surface treatment	Sandblasting nickel plating
Scope of Use	Used to determine the puncture resistance of geotextiles, i.e., the maximum force measured during the process in which a plunger presses against the specimen until it ruptures.
Fixture Specifications	The upper fixture’s piercing tip has a diameter of 8 mm and a length of 50 mm, with a C0.8×45° chamfer on the end face; the lower fixture features an inner bore diameter of 45 mm, a pressure plate with a diameter of 100 mm, and a body height of 150 mm, supplied with a locking wrench.
Optional connector (customizable)	Optional Type A or Type B connector: A connector, shaft outer diameter 20 mm, length 30 mm (with lock nut) B‑type connector: inner bore 20 mm, depth 30 mm; pin hole diameter 10 mm, with the center of the pin hole located at the connector. End-face distance: 14.5 mm.
Note	When no connector is attached, the clamp body has an M12 internal thread.
