Computational Analysis and Comparative Study on Ballistic Impact Properties of Composite Materials

Composite materials assist all types of aircraft, rockets, and missiles to fly higher and faster. However, impacts at high speeds affect aircraft and causes partial or complete penetration. To comprehend the consequences of hybrid composites made of Kevlar and Kenaf fibers when exposed to a high-velocity bullet, this study examines the ballistic impact characteristics. Three plates are designed with three different stacking sequences and impacted with a projectile at different velocities to spot the combination which could withstand the high-velocity impacts. Impact properties like total deformation, direction deformation, equivalent stress, and maximum shear stress are observed and analyzed using ANSYS software. Plate 1 with kenaf as its third layer shows better resistance to high velocity impacts than the other two stacking sequences. Therefore, Plate 1 can be effectively used in high velocity impact applications.
