Abstract
In order to satisfy future requirements of the Canadian Forces in lightweight ballistic armours for personnel protection, nano-composite ceramic materials concepts is explored. The apparent ability of the nanoparticles to deflect cracks represents a major interest for ballistic armour applications. Literature reported that impregnation of nano-particles into various ceramics resulted in either significant improvement or decrease in fracture toughness and hardness. This show the lack of understanding of the relationship between process parameters, microstructure, mechanical properties and the damage mechanisms governing ballistic performance of these ceramics. A Canadian Ceramic Armour Team compose of scientists from several government research organizations in Canada with most of the required technological and testing capabilities has joined their effort to gain this knowledge. This paper presents the 3 years program that began in spring 2010. Preliminary results, mostly from the NRC’s Steacie Institute for Molecular Sciences, show the successful impregnation of single walled carbon nanotubes (SWCNT) additives into the ceramic matrix using the proprietary surface modification process.
