ABSTRACT:
A flexible armor system adaptable to a garment suitable for extremity protection uses planar, polygon-shaped solid elements made of ceramic cores wrapped in high strength fabric and arranged with rotable edge and intersection protection as a flexible mosaic array which is bonded between an elastic strike side spall cover and a high tensile strength flexible backer layer, further supported by a substantial fiber pack. A progressive mode of localized system failure during a ballistic strike includes: a projectile penetrating the spall cover, fracturing the ceramic core of a wrapped SE while being partially deformed; the deformed projectile accelerating the fractured but still wrapped solid element before it so as to free the solid element from the array and drive it through the flexible backer as a combined mass at a reduced velocity into the fiber pack.
