Abstract

In this chapter, advances in ballistic protection are reviewed. Ballistic structures are considered as soft ballistic, fiber-reinforced composite as a front or back face insert plates, shear thickening fluid structure, and nano-ballistic rigid armor. Their substrates as a form of two-dimensional fabric and three-dimensional preforms are explained considering complex impact phenomena during threat-protection interactions. Analytical modeling such as molecular scale, microscale-mesoscale, and macroscale including numerical methods as finite element methods for the estimation of ballistic properties are provided based on commercially developed software packages. Failure modes of the ballistic structures including nano-ballistic are explained regarding high strain rate impact loading. It is concluded that ballistic protection is improved by using high-strength fibers and tough matrices as well as advanced fabric architectures incorporated with recently introduced nanomaterial as a form of nanospheres, nanotubes, nanoplate, and nanofibers and advanced polymer-coating techniques. This resulted in a lightweight ballistic structure with multifunction, better ballistic protection, and comfort to the wearer.
