10 - Ballistic impact response of laminated hybrid composite materials

Abstract

Ballistics impact testing deals with high-speed testing, which is suitable for examining the ultimate impact response of laminate hybrid composites. Limited studies have been conducted on ballistic impact behavior, especially that subjected to hybrid composites. Natural hybrid composites are subjected to an impact response because it is one of the most important behaviors that is widespread owing to its surroundings. The damage to a composite as a result of impact is the most critical characteristic that keeps it from being applied extensively as a hybrid composite material. To determine the effectiveness of such materials in high-performance structural applications, their behavior or response when endangered by a high-velocity impact should be clearly understood. The ballistic impact behavior of a composite is influenced by a few parameters, including geometry, the material, and the projectiles, as is discussed in detail. The dominant failure modes or damage behaviors of the composites dominated by a ballistic impact are fiber fracture or rapture, fiber matrix debonding, delamination and shear cutoff. Lamination of natural fibers with synthetic fibers in the case of composite materials results in the enhancement of ballistic impact performance for this natural hybrid composite.
