In order to achieve enhanced protective and wear (flexibility, less bulkiness) properties of ballistic and stab protectingpanels the investigation of chemical surface modification of woven p-aramid fabrics was performed applying differentchemical composition shear thickening fluid (STF) which improves friction inside fabric structure. For the chemicaltreatment silicic acid and acrylic dispersion water solutions were used and influence of their different concentrations onpanels’ protective properties were investigated. Results of ballistic tests of multilayer protective panel have revealed thatshear thickening effect was negligible when shooting at high energy range (E > 440 J). Determination of stab resistanceof p-aramid panels has shown that different chemical composition of STFs had different influence on protectiveproperties of the panels. Application of low concentrations of silicic acid determined higher stab resistance valuescomparing to higher concentrations of acrylic dispersion water solutions. At this stage of research stab tests results asballistic ones determined that STF application for multilayer p-aramid fabrics protective panels is more efficient at lowstrike energy levels.Keywords: bullet proof vest, shear thickening fluid, aramid fiber, ballistic resistance, stab resistance.
