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 modifi...
A solid propellant having a modified burn rate consisting essentially of: from about 10% to about 25% ammonium nitrate; from about 15% to about 17% nitrocellulose; from about 52% to about 56% of one or more nitrate ester plasticizers; from about 0.5% to about 6.0% carbon fiber wherein said carbon fiber modifies the burn rate of the propellant composition such that a portion of the burn rate versus pressure curve for said propellant has a slope less than or equal to approximately 1.0.
