摘要

Soft body armour panels using p-aramid (Technora) fabrics with three different levels of thread densities were developed in this research. Shear thickening fluid (STF) was synthesized using silica nano-particle (100 nm) and polyethylene glycol (PEG). Fabrics were coated with 60% (w/w) STF to improve their resistance against low-velocity bullets (165 m s(-1)). For neat fabrics, all the bullets fired from 0.38 '' calibre revolver pierced the multilayer fabric panel. However, impact energy absorption increased with the increase in thread density in fabric. After coating with shear thickening fluid, panels having four layers of fabric stopped all the bullets fired. It was possible to reduce the weight of panel by 23% after the STF treatment whilst ensuring bullet stoppage.
