Description
Nanoscale silica particles are functionalized and ultrasonically dispersed into a
mixture of polyethylene glycol and ethanol, and then reinforced with Kevlar. The stab or
puncture resistance of the flexible nanophased materials system supersedes recent
advances made in this area. Through SEM scans, thermal and chemical analysis, it is
evident that the functionalized nanoparticles offer multiple facets of resistance to
penetration of a sharp impactor. The improvement in protection is traced to the
formation of siloxane bonds during functionalization. The framework for a theoretical
model is established to estimate penetration depth under low velocity impact of a sharp
object through the flexible composite. For comparison ofthese novel fabric composites,
a method is also introduced to evaluate penetration resistance quantitatively. The method
is capable of showing subtle changes that would otherwise be missed.
