Elevated Temperature Testing of Metal Matrix Composites Under Rapid Heating Conditions

Source

The Atlantic Research Corporation has designed and built facilities for testing metal matrix composites at elevated temperatures. The facilities are capable of performing tension or compression tests of sheet-type specimens to 1927°C (3500°F) at heating rates in excess of 38°C/s (100°F/s). Tension tests were performed on unidirectional and cross-ply graphite/aluminum, unidirectional graphite/copper, and discontinuous silica carbide/aluminum materials. The continuously reinforced materials exhibited superior room temperature properties and elevated temperature property retention when compared with the matrix metals alone. The elevated temperature response of the discontinuously reinforced SiC/Al was comparable to that of aluminum. These test results indicate the potential advantages of using metal matrix composites in rapid heating, elevated temperature applications, where the temperature may approach the melting point of the matrix material.
