Composite projectile and cartridge with composite projectile
TLDR
In this article, the authors defined a composite of a cured, toughened polymer resin and a particulate filler distributed through the resin, the filler having a density greater than a density of the resin.Abstract:
A projectile includes: (a) a cured, toughened polymer resin; and (b) a particulate filler distributed through the resin, the filler having a density greater than a density of the resin, wherein the projectile has average density less than the density of lead.read more
