Abstract
The piercing resistance of woven fabrics coated with a paste containing one abrasive particle namely silica sand, natural sand, aluminum oxide, titanium dioxide, zirconium oxide, silicon carbide and diamond was studied. The coated fabric was considered as flexible body armor, resisting penetration of a syringe needle. It was found that with
almost all of the abrasive particles, the initial piercing resistance increased steeply with increasing amount of the abrasives and attained a plateau later on. Silicon carbide showed the highest piercing resistance. In fact only two layers of silicon carbide coated fabric (50% on the weight of the fabric) could stop the penetrating needle completely and make it bend. Increasing the amount of binder also led to an improved piercing resistance. The results of this research could provide a good reference for designing and engineering body armors capable of resisting sharp objects penetration.
