ABSTRACT:
A container is disclosed of that type best suited for carrying air freight in wide bodied aircraft, made to the general specifications of an LD3 Igloo which is essentially a nominal five-foot cube, being extended along one direction perpendicular to the fusillage aircraft to slightly over six feet. The subject container is molded of reinforced fiberglass in a semi-monocoque construction, the door opening being a part of the original molded material. The material is characterized by a plurality of layers of fiberglass and resin including matting, roving, and overlapping matting; criss-crossed webbing being provided at the exterior beneath the overlay matting. Each of the fiberglass members as well as the webbing are separated by a layer of resin. A rail is provided around the periphery of a support pallet having an upstanding container flange to which the fiberglass molded portion is secured. In the method, a split mold is employed with one portion of the split mold being complimentary to the tapered end of the container. The molds are coated with Teflon, the various layers of resin and fiberglass and the webbing being applied exteriorly thereto, and heated for curing from the inside. Upon removal, the one portion of the mold which is rectinlinear in configuration is first removed, and thereafter the tapered portion. Thus a mold can be used which is larger in its assembled form than the opening at the bottom of the enclosed container. The door portion is then sawed out of one end, and framing means secured to the opening and the material which is removed becomes the material for the door. Optionally, the mold sections can be provided with air holes so that air can be used in assisting to strip the molds from the container.
