ASTM D6636 | Textiles | Ply Adhesion Strength
ASTM D6636 is a test method used to determine the adhesion strength between reinforced geomembrane plies. It utilizes a T-Peel test technique in order to determine the force per unit width (adhesion strength) necessary to peel an individual ply from a laminated geomembrane material at an angle of 180 degrees.
Before conducting ASTM D6636, it is important to read the entire specification in the relevant ASTM publication.

- Prepare the test specimens as described in the test method, ensuring that they are cut parallel to the scrim of the reinforced geomembrane material.
- Separate plies of the geomembrane such that there are lengths of 1 in. to 2in. to be gripped during the test.
- Clamp the ends of the geomembrane plies into the grips of the testing machine, making sure the ends are centered and there is no twisting of the sample.
- Apply the tensile force to the specimen at the rate specified in the standard and record the force necessary to separate the plies over the specified distance.
- Take care to ensure that the plies are indeed peeling and not tearing during the test.
