Abstract:
1. A particulate capture module for a firearm having a barrel, comprising: a) a particulate capture shell having an inlet and an outlet, the shell inlet being configured to receive the bullet discharged from the firearm wherein the shell inlet of the particulate capture shell is configured to couple with the barrel of the firearm; and b) a self-healing particulate capture material arranged within the particulate capture shell so as to completely occupy a travel path of the bullet so as to cause the bullet to pass through the self-healing particulate capture material, the self-healing particulate capture material being configured to capture particulates associated with discharge of the bullet from the firearm, wherein the self-healing particulate capture material includes a self-healing polymeric material selected from the group consisting of expanded polyurethane, expanded polyethylene, expanded polystyrene, ionomeric metal salt of an ethylene-vinyl copolymer, open cell foams of high internal phase emulsions (HIPEs), copolymers thereof, and composites thereof.
