Tensile Testing of Metal Matrix Composites - ASTM D 3552

"Standard Test Method for Tensile Properties of Fiber-Reinforced Metal Matrix Composites"
ASTM D3552 covers the determination of the tensile properties of metal-matrix composites reinforced by continuous and discontinuous high-modulus fibers. This method applies to specimens tested in a direction of reinforcement or perpendicular to the direction of reinforcement.

A tension specimen is mounted in suitable grips of a test machine and a load is applied at approximately constant crosshead rate until specimen failure occurs. When possible, the load-deformation or load-strain curve is plotted either manually or automatically, to determine elastic moduli and other tensile properties (proportional limit, fracture strain, etc.), as well as the ultimate tensile strength.

Touchstone has performed thousands of such tests on metal matrix composites in support of numerous metal matrix composite development programs. In addition to this test, Touchstone has developed hundreds of other materials characterization tests related specifically to metal matrix.
