Since 1990, TRL has been involved in the development of and the testing of Metal Matrix Composites. In support of this work, Touchstone personnel have been active in the development of MMC testing methods for Military Handbook 17.
Among the hundreds of test methods Touchstone has used to characterized metal matrix composites, TRL has performed virtually all the tests under the Consortium Testing Specification (CTS) for the NASP (National AeroSpace Plane) Materials & Structures Augmentation Program. Publication of these test methods is restricted so they are not described here. The following is a list of the NASP standard tests with which Touchstone has experience.
Touchstone is also experienced with ASTM D 3552, “The Standard Test Method for Tensile Properties of Fiber-Reinforced Metal Matrix Composites.” This method determines 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. In this method, a tensile specimen is mounted in the grips of a test machine and a load is applied at approximately constant crosshead rate until specimen failure occurs. The load-deformation or load-strain curve is plotted to determine elastic moduli and other tensile properties (proportional limit, fracture strain, etc.), as well as the ultimate tensile strength.
