| Abstract Scope |
Multilayered Armor Systems (MAS) with a front ceramic followed by aramid fabric (Kevlar™) are currently used against high velocity ammunition. In these armors, a front ceramic layer that shatters and spalls the bullet is followed by an intermediate layer, usually plies of aramid fabric. In the present work, the intermediate aramid fabric layer was replaced by an equal thickness layer of 30 vol% fique fabric reinforced polyester composite. The fique fabric is made of relatively strong natural fiber with greet reinforcement potential. Ballistic impact test with 7.62 caliber ammunition revealed that both the plain polyester and the fique fabric composite have a relatively similar performance of the Kevlar™. The MAS with fique fabric component attended the NIJ standard for body protection. The energy dissipation mechanisms of fique fabric composite were analyzed by scanning electron microscopy. This latter is the same mechanism recently disclosed for aramid fabric. |
