Barrday U471 2-ply Aramid UD

BarrFlex™ U471 is an advanced para-aramid unidirectional material for hard armor ballistic applications. BarrFlex™ U471 consists of two plies of unidirectional product, cross-plied in 0°/90°Configuration. Each layer is individually constructed within a resin matrix. The resin matrix retains stability at elevated temperatures while the product maintains structural integrity after ballistic event. Material performance is dependent on product orientation. Always ensure the fiber orientation is correct.

Reinforcement Material: Aramid (Kevlar)

Reinforcement Form: Unidirectional Fabric
