Tension and compression test methods for metal matrix composite materials are reviewed in light of experimental and analytical results. These data showed that test results, in particular compressive strength, depend on the test method. Results from a new side-support compression test method where aluminum honeycomb was used as the side-support material are discussed. A simple buckling analysis showed that the support provided by the honeycomb was sufficient to stabilize the specimen. Experimental results showed that the honeycomb, unlike solid metal side-support plates, did not suppress the local buckling failure mode. Results from tests on several boron-aluminum laminates showed that there is significant difference in both stiffness and strength between the honeycomb and steel side-support methods.
