Analysis ballistic impact modeling of multicomponent fabrics with jalaba structure

Abstract

Various textile materials have been employed in the past for protection against the ballistic with only limited satisfaction without realizing in underlying mechanism of ballistic impact. The multicomponent fabrics was prepare by nylon yarn with plain constraction with thickness of 0.18 mm. The multicomponent fabrics were made 35 layers (laminated) with various thickness. A computational constitutive model has been developed to characterize the progressive failure behaviours of multicomponent fabrics with jalaba structure as reinforcement under high velocity impact conditions. Test result indicates that multicomponent fabric with jalaba structure can reach second level of International Standar of NIJ-010104 for hand gun (revolver) at shoot distance 5 meters. If compared with panel from biotextile composite the multicomponent fabrics have advantages in structure stability, flexibility, lightly and confortable. The integrated modeling was sucessful utilized to predict the damage and ballistic bihavior of multicomponent fabrics to various ballistic impact conditions.
