Standard Test Method for Facing Cleavage of Sandwich Panels

Importancia y uso:

4.1 This test method determines the cleavage force required to peel stiff facings from the core of sandwich panels, and is used to determine how well the facing is bonded to the core. Test Method D1781 only works well with flexible facings. As a guideline, the cleavage test method would work better on sandwich panels that have facings with a bending stiffness (EI) of greater than approximately 27.3 lb-in²/inch width (3.09 kN·mm ²/mm width). This converts to approximately 0.032 in. (0.81 mm) 6061 T6 aluminum alloy, 0.023 in. (0.57 mm) steel, and 0.046 in. (1.18 mm) fiberglass facings.
