SAPI Plates - Prepare and Protect

New ESAPI plates are also made of boron carbide. The standard plates are not given an NIJ rating, as they are tested in accordance with specific protocols for the military and not the NIJ's testing. Military testing calls for survivability of three hits from the round marked on the plate – for standard SAPI, of a caliber up to 7.62x51mm ...

The E-SAPI test is very similar to the NIJ Level IV test, but just a little bit tougher. Mil-spec calls for the plate to stop one round of .3006 AP, just like Level IV, but it must also stop a second round, 60% of the time ( not of the time - too much of a weight penalty). E-SAPIs are made with the very expensive boron carbide material to ...

Conformal Ceramic Composite Armor System (CCCAS), page 1

The boron carbide is so hard of a material that it deforms steel, copper and lead right on the surface with no significant cracking. It is similar to the ceramic formula used in dragon skin armor and the Ceradyne ballistic boron carbide hot pressed plates currently used by US forces. We have filed a provisional patent on the system.


Boron carbide is an excellent armor material with a decades-long history of use, but bulk diamond effectively renders it obsolete. Bulk polycrystalline diamond tiles are many times harder than boron carbide, many times tougher, many times stronger, and, ultimately, have a firm performance edge.
