Abstract

Propellant formulations are provided which include non-toxic burn rate modifiers. In order to produce a usable propellant formulation, it is necessary to control the burn rate of the propellant. Failure to adequately control the propellant burn rate often results in unacceptable performance of the propellant. It has been found that carbon fibers are capable of modifying the burn rate of propellants without resorting to lead as a burn rate additive. Accordingly, the use of from about 0.5% to about 6.0% carbon fibers is taught as effective burn rate modifiers in propellants, in order provide non-toxic means for modifying the propellant burn rate.
