Abstract

Techniques and processes that combine particulate coating processes with particulate handling steps resulting in the formation of free-flowing particulates for introduction into energetic product vessels to affect an in-situ, net-shape manufactured product. The processes involve selecting suitably sized materials, processing such materials such that they are surface-coated and/or locally “structured” particulates, and pouring, preferably “dry” pouring, these processed materials into an energetic product vessel and infusing the filled vessel with a polymerizable and surface-compatible monomer or oligomer which flows into the unoccupied volume, followed by polymerization of the monomer, which then becomes the binder giving mechanical integrity to the final, net-shape energetic composition.
