Abstract

According to one embodiment, an armor system includes one or more composite armor panels including one or more layers of fibers including a first fiber weave, such that a first directionality of one or more fibers of the first fiber weave is configurable to reshape a projectile based on one or more angles of the first directionality of the one or more fibers of the first fiber weave. The armor system also includes one or more composite armor panels comprising one or more layers of fibers including a second fiber weave, such that a second directionality of one or more fibers of the second fiber weave is configurable to reshape the projectile to a new shape based on one or more angles of the second directionality of the one or more fibers of the second fiber weave.

Description

TECHNICAL FIELD[0001]This invention relates generally to the field of armor systems and more specifically to reshaping projectiles by light weight armor systems to protect against shape charges (e.g., an explosively formed penetrator (EFP)), other explosive devices, hypervelocity impacts and / or ballistic devices.BACKGROUND[0002]Improvised Explosive Devices (IEDs) and shape charges such as Explosively Formed Penetrators (EFPs) have accounted for a large number of combat casualties. Lethality of EFPs comes in part from the shape and arrangement of a concave copper cone, called the liner, which transforms into a forceful jet of fluidic metal which easily perforates steel armor. Despite focused efforts on armor development, Mine Resistant Ambush Protected (MRAP) vehicles and other armored vehicles still cannot defend against these threats. More recently, armor solutions such as the FRAG Kit 5 have been used to protect military vehicles such as Humvees. However, these armor solutions typ...
