ASTM D Composite Shear Testing – ADMET

Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes. Place the specimen loosely into the fixture making sure the notch alignment tool is pulled up into the notch.

ASTM D is a testing standard designed to measure the shear properties of composite materials. ASTM D Either in-plane or interlaminar shear properties may be evaluated using ASTM D depending upon the orientation of the material coordinate system relative to the loading axis.

Make sure that the specimen is centered in the fixture and that it is contacting both upper and lower grip jaws on both sides while still being supported on the back side. ASTM D covers the shear properties of composite materials reinforced by high-modulus fibers. Link to Active This link will always route to the current Active version of the standard.
