Abstract EN
We report improving ballistic performance of polyurethane foam by reinforcing it with nanoscale TiO2 particles.
Particles were dispersed through a sonic cavitation process and the loading of particles was 3 wt% of the total polymer.
Once foams were reinforced, sandwich panels were made and impacted with fragment simulating projectiles (FSPs) in a 1.5-inch gas gun.
Projectile speed was set up to have complete penetration of the target in each experiment.
Test results have indicated that sandwich with nanophased cores absorbed about 20% more kinetic energy than their neat counterpart.
The corresponding increase in ballistic limit was around 12% over the neat control samples.
The penetration phenomenon was also monitored using a high-speed camera.
Analyses of digital images showed that FSP remained inside the nanophased sandwich for about 7 microseconds longer than that of a neat sandwich demonstrating improved energy absorption capability of the nanoparticle reinforced core.
Failure modes for energy absorption have been investigated through a microscope and high-speed images.
