Abstract

An assembly useful for constructing concealable, flexible, lightweight protective body armor includes a flexible support layer to which is bonded a mosaic of rigid, adjacent tiles having a high bending performance, such as type 5 titanium alloy, which includes 6% aluminum and 4% vanadium by weight. The inner support layer can include woven para-aramid and/or STF-treated Kevlar™. The tiles can have interlocking and/or thickened edges. An additional backing layer can include para-aramid and/or carbon nanofiber embedded UHMWPE UD-laminate. An inner layer can have high moisture transport, anti-microbial properties, and low friction. An outer layer can be shaped with anatomical features to hide the armor. The assembly can be flame resistant. Assemblies with 2 mm thick tiles and total thickness less than 5 mm can provide V50 protection against 9 mm FMJ projectiles at more than 1000 feet/second, and can also protect against knife and spike assaults at 65 Joules force.
