A program was conducted in four phases to develop safe, cost effective process methods for salvaging and recycling composite cases from solid propellant rocket motors. Motors were evaluated, ranging in size from 4,000 to 200,000 lb, loaded with Class 1.1 or 1.3 propellant. During Phase I, a literature search was conducted to determine the current state-of-the-art status of operations applicable to case salvage operations. Emphasis was placed upon propellant removal methods, insulation and case repair methods, and disposal of explosive wastes. An initial assessment was made of methods that appeared to be promising. Computerized cost models were developed during Phase II for estimation of case salvage costs and the costs of fabricated new cases. Parameters considered in the computation of case salvage costs included the level of salvage, motor size, type of propellant, method of waste disposal, inspection and qualification requirements, the number of units to be salvaged, the production rate, and the methods utilized for propellant, liner and insulation removal. During Phase III, laboratory studies were conducted to investigate new and existing methods for propellant and insulation removal and to evaluate the effect this processing would have on insulation and case integrity.
