ASTM D Composite Shear Testing – ADMET

The sample preparation, including notching, can be done at astm d5379 facility or by Touchstone. The composite materials are limited to continuous-fiber or discontinuous-fiber-reinforced composites in the following material forms:. The test determines shear strain, shear stress and shear modulus. The lower fixture should be mounted astm d5379 a base plate that supports a linear bearing shaft.

The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other. Either in-plane or interlaminar shear properties may be evaluated, depending upon the orientation of the material astm d5379 system relative to the loading axis.

ASTM D testing determines the shear properties of composite materials that are reinforced by high-modulus fibers. Properties determined from this test may be used for material specifications, research and development, quality assurance and structural design and analysis.
