DEVELOPMENT OF METAL LAMINATES WITH HIGH DAMPING CAPACITY.
Abstract
This report describes techniques developed for the manufacture of flat panels three feet by four feet in size and having a net thickness of steel of 3/8 inch for use as fairwater and superstructure plates on submarines. The panels consisted of six 1/16-inch thick layers of mild steel interleaved with 10-mil thick layers of a Neoprene ILA compound. Various methods of cutting, machining and forming the panels to desired contours were investigated. It was found that the panels can be cut with a band-saw to desired sizes and machined with the usual cutting tools providing the panels are kept cool during these operations. It was also found that the panels could be bent satisfactorily only with radius dies and then only if the panels were totally enclosed within mating dies. The minimum radius of curvature to which panels of practical size could be bent was 48 inches. Bending of the panels to this curvature had no significant effect on the bond between the steel laminae and interlayer material or on damping behavior. (Author)
