<\/u>Se trata de la patente de invenci\u00f3n de un Proyectil de Mortero, que incluye una superficie interior met\u00e1lica vinculada con la carga explosiva, una superficie exterior de pol\u00edmero y fibras de alta resistencia. Entre ambas superficies, una capa de fragmentos met\u00e1licos de diferentes dimensiones y no conectados entre ellos. El desarrollo de nuevas municiones empleando\u00a0materiales compuestos, con patrones de fragmentaci\u00f3n m\u00e1s controlados y modernos materiales, constituye un \u00e1rea de I&D\u00a0 importante de bal\u00edstica terminal de proyectiles, para armas de gran vigencia como los nobles morteros.<\/p>\n
A mortar shell including: a metallic inner layer; a polymer outer layer having reinforcing fibers dispersed therein; and at least one layer of metallic fragments disposed between the inner and outer layers, the layer of metallic fragments including a plurality of individual metallic fragments unconnected to each other. In a variation, the mortar shell including: a metallic inner layer, the metallic inner layer having a grid formed on an outer surface to define a plurality of metallic fragments separated by grooves; a polymer having first reinforcing fibers disposed within the grooves; and a polymer outer layer having second reinforcing fibers dispersed therein. In another variation, the mortar shell including a polymer outer layer having reinforcing fibers dispersed therein; and a metallic inner layer having a plurality of metallic fragments with a shape to interlock to each of the other and assembled together into the metallic inner layer.<\/p>\n
