Abstract:

Metal matrix composites consisting of boron reinforced aluminum, boron-aluminum-titanium, and Borsic reinforced titanium were fabricated to achieve improved impact tolerance. Test procedures included both static, instrumented pendulum impact, and ballistic impact. It was demonstrated that composite specimens can be fabricated and tested to achieve a wide range of impact resistance. Energy dissipation can exceed that of monolithic engineering alloys, however, this superiority is very geometry dependent.
