Abstract : A Canadian ceramic armour team composed of scientists from several government research organizations in Canada was formed to explore the potential of composite ceramic materials for personal armour applications. Methods to impregnate and integrate single walled carbon nanotubes additives into ceramic matrix of Al2O3 were explored. Various volume of single wall carbon nanotubes as well as different processing approaches were used to prepare samples in an attempt to optimize mechanical properties. The processing approaches investigated were pressure less sintering, hot-pressing and hot isostatic pressing. Other Al2O3 ceramic composites were also fabricated and evaluated. These included Al2O3 composites reinforced with Al2O3 fiber fabric and Al2O3 fiber fabric with multi wall carbon nanotubes grown onto the fiber surface. Those composites ceramic sample were tested, and the results were compared with some of the commercial single component armour ceramic. Boron nitride nanotubes, being thermally more stable then carbon nanotubes, were also investigated as an alternative to the single wall carbon nanotubes. In this paper, parameters influencing mechanical properties of composite ceramic armour are discussed. Results from mechanical properties are shown.
