Abstract
The present disclosure describes articles that may be used in protective gear, including but not limited to body armor, helmets, shields, or barriers. These articles may include a polymeric material coated with nanoparticles, in a single layer or in multiple layers, which are treated to form a composite. The articles may further include a ceramic layer and/or a back-face layer. Such articles may be useful for protecting an object or wearer against projectiles.
Claims9
A method for producing a composite for a protective apparatus, comprising steps of:
- providing a polymeric material comprising polyethylene, ultra-high molecular weight polyethylene, polypropylene, para-aramid, polyether ether ketone, polyaryletherketone, polyepoxide, or combinations thereof,
- coating the polymeric material with nanoparticles using a coating method to produce a coated polymeric sheet, wherein the nanoparticles comprise carbon nanotubes, graphene, silicon dioxide, boron nitrite, or combinations thereof, and
- treating the coated polymeric sheet using a treatment method to form a composite, wherein the treatment method comprises hot pressing the coated polymeric sheet at a temperature of 100° C. to 400° C. and a pressure of 100 bar to 400 bar,
- wherein the composite has an areal density of at most 40.0 kg/m2 and exhibits a back-face signature of at most 44 mm when struck with a 7.62×51 mm NATO projectile.
