| Summary: | With each passing year, multi-layered armours for military vehicles become more and more advanced to meet growing demands and counterpart novel offensive solutions. Layers that are responsible for track deviation and blunting of the projectile, typically made of hard ceramics, are nowadays considered to be replaced by ceramic composite. In this study, two ceramic systems composed of the TiB2 matrix and SiC or SiC/TiC reinforcement phases were fabricated from mixture of B4C powder with different amount of TiSi2 or Ti5Si3 intermetallic phases. Importantly, the desirable microstructure was obtained by reactive sintering at 1550°C and pressure of 2.5GPa. The obtained ceramic composites underwent dynamic loading tests to evaluate their applicability for ballistic shields. Two systems were then compared in terms of the potential pulverization rate which determines usability as a primary layer for a multi-layered vehicle armour. |
