Abstract
A precursor formulation of an energetic composition with improved electrostatic charge dissipation, including an amorphous carbon black having a specific surface area of at least about 1,200 m2/g, in an amount from about 0.05% by weight to about 0.25% by weight. Also disclosed is a precursor formulation of a propellant composition with improved electrostatic charge dissipation. The amorphous carbon black having a specific surface area of at least about 1,200 m2/g may enhance electrostatic charge dissipation of the HTPB-based propellant composition, without affecting a breakdown voltage of the propellant composition.
Claims1
A precursor formulation of a propellant composition, consisting of:
- aluminum, ammonium perchlorate, and a binder consisting of a hydroxyl terminated polybutadiene (HTPB);
- at least one of a bonding agent, a plasticizer, or a crosslinking agent;
- and
- a conductive, amorphous carbon black having a specific surface area of at least about 1,200 m2/g, the conductive, amorphous carbon black comprising from about 0.05% by weight to about 0.25% by weight of a total weight of the propellant composition.
