Development of Stab Resistant Body Armor Using Silated SiO2 Nanoparticles Dispersed into Glutaraldehyde

The development of flexible body armor has first be en based on Shear Thickening Fluid (STF) which is a mixture of polyethylene glycol (PEG), water and silica at a specific weight ratio. The making process has been improved in incorporating through sonicating the silica particl es to the mixture. Although the performances obtained were improved the stab resistance was not completely opt imized to stop a penetration more than 45J/g/cm≤. The inte ntion in this investigation was to study the actual componen ts of the armor composite and to improve its stab performances. The outcome is a completely new approach regarding the fabrication route which differs from the previous S TF making process. PEG has been removed and an extra component has been incorporated into the mixture. I t is believed that this is the addition of this new chem ical: Glutaraldehyde which provides the phenomenal stab performances.
