Abstract : A study was conducted to determine the feasibility of producing perforated, thin-walled hollow polyethylene spheres and to produce pilot quantities of both 1 and 3/4-inch diameter spheres. The projected use for these spheres was as a fire control and explosion suppressant filler material for aircraft fuel tanks. Methods of producing thin-walled hollow plastic spheres were studied including: thermoforming, blow molding, injection molding and trapforming. Trapforming was selected as the most suitable method and the spheres were produced by this technique. (Author)
