摘要：
Impact energy absorption capacity of Kevlar woven fabrics has been improved using silica particle based shear thickening fluid (STF). The influence of padding pressure and silica concentration in STF on add-on%, yarn pull out force and impact energy absorption has been studied. Higher padding pressure reduces the STF add-on%, but increases the impact energy absorption. Therefore, it is possible to achieve enhanced impact energy absorption performance at lower STFadd-on%, i.e. lower fabric weight. It is also understood that the yarn to yarn friction, as measured by the quasi-static yarn pull-out force, only partially influences the impact performance of STF treated Kevlar woven fabrics.
