Aluminum Ceramic Armor

The mechanical properties of a few types of ceramic armors are displayed in the table below.

Aluminum ceramic armor.

Who developed ceramic aluminum armor system and later studied the penetration mechanism of such armor. Ceramics are often used where light weight is important as they weigh less than metal alloys for a given degree of resistance. Areal density measured in kg m 2 the lower this is the more weight efficient the armor. Likewise common ceramic body armor components in the market are cerashield high density aluminum oxides cerashield silicon carbides and cerashield boron carbides.

Aluminum encapsulated ceramic tiles for hybrid armor brian wang january 16 2011 cps technologies cps has developed a technology for improving the toughness of ceramic tiles in composite armor systems by selectively reinforcing them with metal and metal matrix composites mmc and then packaging them in a hermetic layer of high pressure. Certain grades of ammunition cause more damage to composite ceramic body armor than steel body armor plates but certain rounds such as ar 15 rounds can penetrate steel armor easier than ceramic body armor. The aim of this work is to present results of mechanical characterization and ballistic test of alumina based armor plates. Three compositions 92 96 and 99 wt al 2 o 3 were tested for 10 mm thick plates processed in an industrial plant.

The development of lightweight ceramic metal armor is based on the pioneering work of wilkins et al. It is now well known that the high hardness ceramic deforms and erodes the penetrator through a. This powder is then molded subjected to high heat and baked just as any other ceramic is baked. Quantifying and optimizing ceramic armor systems require attention to the following factors where rha armor steel is the reference material in all cases.

Mechanical properties of ceramic armor. Chobham armour is the informal name of a composite armour developed in the 1960s at the british tank research centre on chobham common surrey the name has since become the common generic term for composite ceramic vehicle armour other names informally given to chobham armour include burlington and dorchester. Samples were pressed at 110 mpa and sintered at 1600 c for 6 x2009 h. Ceramic armor is armor used by armored vehicles and in personal armor to resist projectile penetration through high hardness and compressive strength.

Projectile velocity for a given projectile type armor system and ad value at which 50 of impact events correspond to penetration and. The most common materials are alumina boron carbide silicon carbide and titanium diboride. A comprehensive summary of lightweight armor development is given by viechnicki et al.
