| Abstract Scope |
Protection requirements for the vehicles, platforms and critical parts is ever-increasing as a result of the advanced technology enabling harder missions day by day. Composite armor structures offer lightweight, durability and impact resistance thanks to grouping of different materials. Ceramics are employed in composite armor applications to provide high hardness on the front layer to interact with the projectile to deform and decrease its kinetic energy. Ceramic-matrix composites (CMC) showcase similar hardness characteristics to monolithic ceramics while exhibiting higher fracture toughness and lower density, which eventually results as better ballistic properties. We hereby developed novel binary B4C-TiB2 and ternary B4C-SiC-TiB2 CMC materials to serve as hard ceramic facing layer in composite armor applications. Phase distribution and microstructural analysis of the developed CMC’s were carried out and crack propagation mechanisms in CMC structures were evaluated correspondingly. Ballistic tests were also performed on the CMC’s for comparison purposes with commercial ballistic ceramics. |
