Abstract (en)
Nonlethal firearm projectile is made of a soft elastic composite material (I) comprising a particulate metal filler dispersed in a crosslinked polybutadiene matrix, where (I) has a Shore hardness of 2-30 and a density of 1.0-2.9, the filler has a density of 4-22 and the crosslinked polybutadiene has chains with a number-average molecular weight (Mn) of 500-10,000. Independent claims are also included for: (1) A process for producing the projectile, comprising: (a) mixing a liquid polybutadiene having reactive terminal groups and an Mn of 500-10,000 with a crosslinking agent and the filler; (b) introducing the resulting heat-curable paste into a mold; (c) crosslinking the polybutadiene by heating; and (d) removing the projectile from the mold; (2) a composite material as defined for (I); (3) a cylindrical firearm cartridge containing at least one projectile as above.
Abstract (fr)
Le présente invention est relative à un projectile non létal pour arme à feu, constitué en un nouveau matériau composite mou et élastique comprenant une matrice organique polymérique et une charge pulvérulente métallique de densité comprise entre 4 et 22 dispersée dans la matrice polymérique. Le matériau composite a une densité comprise entre 1,0 et 2,9 et une dureté Shore A comprise entre 2 et 30. La matrice organique polymérique est un polybutadiène réticulé comprenant des chaînes polybutadiènes de masse comprise entre 500 et 10000 reliées par des ponts. Le projectile selon l'invention permet de neutraliser un animal ou une personne sans mettre sa vie en danger ni entraîner des blessures graves, même pour un tir à faible distance, inférieure à 5 m.
