New types of armor could be used as a shield in military vehicles to provide better protection from bullets, as well as in spacecraft to mitigate the impacts of meteorite debris.
Like this rubber nanomaterial whose shielding power exceeds steel or kevlar and has been developed by engineers from the University of Wisconsin – Madison.
Engineers have devised ultrathin films only 75 nanometers thick of a relatively common polymer: polycrystalline poly (vinylidene fluoride-co-trifluoroethylene).
According Ramathasan Thevamaran, professor of engineering physics at UW-Madison, and the postdoctoral associate researcher Jizhe cai They have thus shown that the material was superior in energy dissipation from microprojectile impacts in a wide speed range. As Thevamaran explains:
When we scaled the polymer down to this nanoscale, we found that its internal microstructure completely changed unexpectedly compared to its larger scale. Surprisingly, the energy absorption mechanisms in the material became very prominent, and we found that this particular polymer performed significantly better than any other material, both large materials and previously reported nanomaterials, in absorbing energy from projectiles.
With everything, Thevamaran warns that the rubbery nature of this material would make it difficult to use for applications such as bulletproof vests, because the impacts of the bullets would protrude into the material and could cause blunt trauma injuries to the user.
This new material resists projectile impact better than steel or kevlar
