Abstract : This patent discloses a stress reducing liner for a solid rocket motor comprising a first layer of polybutadiene based material, a second layer of perforated silicone rubber and a third layer of polybutadiene based material is fabricated by coating the inner surface of a rocket motor casing with a curable polybutadiene based first layer material, simultaneously heating and spinning the casing to cure the material in an even layer, placing performated silicone rubber over the cured first layer, coating the silicone rubber layer with another uncured polybutadiene based material and repeating the simultaneous heating and spinning procedure.
