High-performance ballistic fibers

Abstract Dyneema® ultra-high molecular weight polyethylene (UHMWPE) fibers are the strongest and lightest fibers available. Its fiber composites are widely used in high-performance ballistic applications. The chapter describes the changes observed in mechanical properties going from single filaments to thick composites. The mechanism of penetration of composites sheets and panels is described, revealing simple characteristics. Numerical modeling approaches with increasing complexity and their sensitivities of the ballistic performance related to the fiber mechanical properties are discussed. Finally, the next generation of Dyneema® fibers and their composites are reported to enable drastic reductions of armor weight.
