ASTM D3479 Tension-Tension Fatigue of Polymer Matrix Composite Materials

ASTM D3479 determines the fatigue behavior of polymer matrix composite materials subjected to tensile cyclic loading. The composite material forms are limited to continuous-fiber or discontinuous-fiber reinforced composites for which the elastic properties are especially orthotropic with respect to the test direction. ASTM D3479 is limited to un-notched test specimens subjected to constant amplitude uniaxial in-plane loading where the loading is defined in terms of a test control parameter. The primary test result is the fatigue life of the test specimen under a specific loading and environmental condition. Replicate tests may be used to obtain a distribution of fatigue.
