A flexible composite suitable for use in a knife, pick, bullet and fragment-resistant article comprising

Ballistic and stab resistant composite

A composite hybrid cord comprising a core comprising of a first bundle of synthetic filaments having a filament tenacity of from 10 to 40 grams per decitex and a plurality of cabled strands helically wound around the core, each cabled strand comprising of a plurality of metal strands helically wound around a center second bundle of synthetic filaments that have a filament tenacity of from 10 to 40 grams per decitex. The ratio of the largest cross sectional dimension of the first bundle of synthetic filaments to the largest cross sectional dimension of the second bundle of synthetic filaments is from 1.5:1 to 20:1. The metallic filaments of the cabled strands have an elongation at break that is no more than 24 percent different from the elongation at break of the synthetic filaments of the first and second bundles.
