ASTM D3039 covers the determination of the tensile properties of resin-matrix composites reinforced by oriented continuous or discontinuous high-modulus greater than 20 GPa (>3X10^6 psi) fibers.

This test determines in-plane tensile properties of polymer matrix composite (PMC) materials reinforced by high-modulus fibers. Composite material forms are limited to continuous-fiber or discontinuous-fiber reinforced composites where the laminate is balanced and symmetric with respect to the test direction.

Touchstone engineers are experienced in specimen preparation and tabbing (which are key to accurate results) for ASTM D3039 and many other test methods.

A tensile specimen is mounted in the grips of the testing machine. Usually, load deformation or load strain curves are plotted or digitally collected during the test for the determination of the elastic modulus.
