When it comes to providing general protection for the most in extremely violent situations, armors have gone through a series of innovations and infections to make this possible. In the past, hides and skin provided the protection needed against harmful elements. In modern times, armor plates, bulletproof vests, and admitted tanks incorporate a more sophisticated technology to provide protection against warheads. Indeed many super-strong materials besides metal plates have been discovered. One of these is ceramic armor. Advanced ceramics allows for the production of super-strong ceramic materials, which are used in ceramic armors. In fact, since the 90s, ceramic armors have been used to protect vehicles and military personnel from sustaining fatal injuries.
Ceramics are one of the hardest, lightweight materials known to man. Since their discovery as potential replacements for metal plates and other armor materials, ceramic materials have been used extensively to develop millinery hardware like armored plates, armored vehicles, and body armors.
Unlike other materials, ceramic armors do not just catch bullets; they have a structure that shatters the bullets upon impact. This is why they are used extensively in the armor system. The strongest and lightest known ceramic is boron carbide. Lately, another strong ceramic material, silicon carbon, has been employed alongside boron carbide, in making ceramic armors.
In bulletproof vests, ceramic plates are used as inserts to prevent the penetration of bullets upon impact. In fact, they’re built in such a way that they deflect the bullets with almost the same force with which they hit any vest with a ceramic insert. And with advanced ceramic technology, which helps in minimizing the size of the ceramic tiles, making them as small as possible, armor plates can retain their integrity even after multiple impacts. In this case, the matrix elements in the plates have a minimum thickness of 1 inch.
Boron carbide ceramic material, for this reason, makes for perfect protection against military warheads.
There are several ceramic materials today (examples include aluminum oxide, silicon carbide, boron carbide, and aluminum nitride). However, as regards making body armors/armor plates, boron carbide happens to be the most preferred choice of strong ceramic material and even in other applications. In the U.S. military, Small Arms Protective Inserts (SAPI) are the ceramic plates used in body armors, and are made of boron carbide.
Boron carbide is notable for its high specific stiffness and strength and chemical inertness, which is typical of most ceramic materials in the complex environment, making its application in the armor system very promising. The surfaces of armor plates made of boron carbide cause the bullets hitting it to lose their force and then surface to shatter into small, hard particles. As the bullet tries to go deeper, the armor ceramics insert forms a fragmented layer. Based on this, the tensile stress within the material causes the ceramics to shatter the bullet. It then absorbs the remaining energy from the bullet and dissipates it within the armor backplate.
Boron carbide ceramics came into the limelight in the 1960s when they were first used in designing bulletproof vests. They also fit into the seats of airplane pilots for added protection. Since then, bulletproof ceramic armor has been incorporated into US tanks, military aircraft, and other advanced armors. The same applies to several other military powers around the world. Some common ceramic armors are Norbide Hot Pressed, Saphikon Sapphire, and Hexology Sintere.
Some of the most common applications of ceramic armor, if which boron carbide is one are:
Here are some of the reasons ceramic armor come tip of the list:
Boron carbide is the strongest and lighter ceramic material, making it a perfect material for ballistic protection. It can also be used in providing protection in military aircraft, tanks, marine crafts, and other land vehicles.
