Abstract
The present disclosure describes compositions combining 1,3,5-trinitro-1,3,5-triazinane (RDX)-based rubberized explosive and thermally-expandable microspheres (TEMs), to create explosive and or propellant compositions which are switchable in detonation properties, and methods for making and using such compositions.
Claims16
A method of making an explosive composition comprising combining 1,3,5-trinitro-1,3,5-triazinane (RDX)-based rubberized explosive with thermally-expandable microspheres (TEMs) wherein said combination formulation allows for tuning detonation properties of the explosive composition.
A method for transforming a detonable material to a non-detonable material by heating the detonable material to create voids that are too large to function as critical hot spots.
A method for making 1,3,5-trinitro-1,3,5-triazinane (RDX)-based rubberized explosive switchable, comprising making an explosive composition by combining 1,3,5-trinitro-1,3,5-triazinane (RDX)-based rubberized explosive and thermally-expandable microspheres (TEMs), subjecting the explosive composition to heat treatment at about 95° C.
A method for making 1,3,5-trinitro-1,3,5-triazinane (RDX)-based rubberized explosive switchable, comprising making an explosive composition by combining 1,3,5-trinitro-1,3,5-triazinane (RDX)-based rubberized explosive and thermally-expandable microspheres (TEMs), manufacturing the explosive composition to be below the material's critical thickness.
A method for making 1,3,5-trinitro-1,3,5-triazinane (RDX)-based rubberized explosive desensitized for detonation, comprising making an explosive composition by combining 1,3,5-trinitro-1,3,5-triazinane (RDX)-based rubberized explosive and thermally-expandable microspheres (TEMs);
- treating the explosive composition to heat treatment at about 95° C.
A method for making a switchable explosive composition that is non-explosive, sensitized to be explosive comprising;
- first making an explosive composition that is desensitized to explosion by combining 1,3,5-trinitro-1,3,5-triazinane (RDX)-based rubberized explosive and thermally-expandable microspheres (TEMs), subjecting the explosive composition to about 95° C. heat treatment, creating a desensitized explosive composition;
- second, subjecting the desensitized explosive composition to about 125° C. heat treatment, creating a sensitized explosive composition.
