Ceramic Armor Materials

Current design trends indicate wider use of ceramics, for vehicle armoring as they
lower the overall weight, while enhancing abilities to defeat ballistic
threats. Composite ceramics can be used in layered formations, matrixes of
different materials or monolithic elements. Typical materials used for this
application are Alumina, silicon carbide (SiC), boron carbide (B4C)
and titanium carbide and titanium diboride, these are lighter than most metals, including titanium,
by a factor of 2 – 3. While monolithic ceramic elements can be used, most
vehicle protection applications are utilizing composites of several materials,
which offer improved endurance tenacity, imperative for advanced protection and
survivability.
The physical properties of ceramic materials have been
recognized for many years. However, manufacturing techniques limited their utilization
to relatively small parts and simple shapes. Recent advances in manufacturing process
offer lower cost production techniques of larger, more complex structures. Some
of these cutting edge procedures are also employing exotic technologies which
dramatically improve the physical characteristics of the end product. Among
these are the Fibrous Monoliths (FM) and
Displacive Compensation of Porosity
(DCP) ceramic materials manufacturing technologies, the use of
nanoparticles in
raw material powders and coating, and
deposition new concepts for treatments of metallic structures – such
as metal matrix composites (MMC), and
liquidmetal.
