An improved rocket motor has a first layer of silicone rubber and a second layer of an ablative lining placed between the rocket motor casing and the propellant grain. The ablative lining layer contains chopped novoloid fibers 14 microns in diameter and nominally 1 mm in length interspersed throughout a polymeric composition.

An improved end burning rocket motor having reduced propellant grain coning and diminished carcinogenic by-products comprising: a tubular shaped casing having an inner surface, a silicone rubber layer on said surface; an ablative lining on said layer made from a mixture of about 74.5 percent by weight polypropylene glycol, about 1.0 percent by weight N-Mono(hydroxyethyl)-N,N′,N′-tris(2-hydroxypropyl)ethylenediamine, about 10.38 percent by weight toluene-2,4-diisocyanate, about 0.62 percent by weight N-phenyl-N′-cyclohexyl-p-phenylenediamine, about 10.0 percent by weight TiO2, about 2.0 percent by weight novoloid fibers, and about 1.5 percent by weight ferric acetylacetonate; and propellant grain bonded to said lining.
