Abstract:

Studies have been conducted on both metal matrix and non-metal matrix reinforced systems. Emphasis has been placed on fabricating high quality and reproducible specimens from each of these primary groups. In addition, tests have been conducted on specimens received from industrial sources. Mechanical properties tests have been conducted in order to investigate composite strain rate sensitivity and load carrying capability. Further, failurefracture studies have been conducted by projecting the various composite specimens at a rigid elastic target. Analytical criteria have been utilized in order to establish predictable bounds on composite failurefracture characteristics for potential application to terminal ballistics design. Finally, studies of wave propagation, attenuation, and dispersement have been conducted in order to establish criteria for evaluating energy transfer and absorption properties of composites as well as varying wave speeds for failure by controlled fragmentation.
