ASTM D3039 Tensile Testing Advanced Composite Materials

Advanced composite materials, such as reinforced polymer matrix composites, are desirable to many industries due to their light weight combined with high stiffness and strength. When creating new and improved reinforced polymer matrix composites, researchers commonly use ASTM D3039 testing standard.

ASTM D3039

ASTM D3039 determines the tensile properties of polymer matrix composite materials reinforced by high-modulus fibers. ASTM D3039 will help determine ultimate tensile strain, modulus of elasticity, ultimate tensile strength, Poisson’s ratio and transition strain for your advanced composite. To begin testing, take a thin flat strip of material with a constant rectangular cross section and mount it in the grips of a tensile testing machine. Perform a minimum of five tests per specimen. Tensile strength is then calculated from the maximum load carried before failure.

Equipment required

Choosing a carefully aligned machine and grips is important for testing in accordance with ASTM D3039. Excessive bending leads to premature failure and an inaccurate test of elasticity, which can occur with a misaligned machine or misaligned grips. Our test engineers will find the most accurate test machine and accessories that are right for your tensile testing application.
