REVIEW OF CANDIDATE STRUCTURAL MATERIALS FOR AN ARCTIC SURFACE EFFECT VEHICLE

A number of candidate structural materials considerd appropriate for the proposed arctic surface effect vehicle are identified by class and by specific type. A discussion of the effect of low temperatures on structural materials is followed by the detailing of various aluminum, titanium, nickel, and steel alloys with their respective advantages and disadvantages. Properties discussed are cost, marine corrosion, strength, toughness, and fatigue strength at room temperature and at -65F. Structural plastics (glass-reinforced and filament-wound plastics, and Boron/Carbon fibers) are also considered. Although most of the material properties are known, the specific application of an alloy to a particular section of the proposed craft is not possible, owing to the present lack of design details. From the structural materials point of view the most critical craft operating environment appears to be the summer open-ocean condition. There are, however, several unresolved problems imposed by the arctic environment and a discussion of these is included. The appendix is an annotated bibliography of selected surface effect vehicle references. (Author)
