Study of Ballistic Textiles Based on Ultra-High Strength Fibres

The work is focused on mechanical and ballistic properties of textile materials most used in personal protection (ballistic vests, helmets), i.e. aramid fabrics. Physical and mechanical properties such as Young’s modulus, maximum strength before rupture, tensile strength, elongation at rupture and combustion velocity were measured. Ballistic resistance of sets of selected fabrics was tested. Ballistic tests were focused on protection level TBO-2/CZ according to CSN 395360. Differences in physical and mechanical properties of commercial fabrics used as inner soft armour and fabrics used for trauma effect reduction were observed. It was found out that different order and combination of different types of textile fabrics influence significantly the ballistic efficiency of fabric sets.
