COMBINING SCHEDULED REDUCTION WITH WEIGHT CONTROL

Not Available The objective of the proposed work is to develop Lattice Block Material (LBM) as a cost effective fabrication technology for ultra-light steel structures. Specifically, JAMCORP proposes to develop manufacturing methods for producing LBM with densities less than 50% that of the bulk alloy. Lattice Block Materials are a new class of materials which make use of the well understood principles of trusses and space frames. These principles are applied at a size previously thought to be impractical for manufacturing. JAMCORP has successfully developed and demonstrated a manufacturing process to produce components having unusually high strength to weight ratios. The physical properties of LBM, such as temperature resistance and hardness, closely reflect the physical properties of the parent material whether it be a metal, an alloy, or a polymer. Cost-effective LBM manufacturing will enable significant reductions in structural component weight. Analysis indicates that hundreds to thousands of pounds could be eliminated from military and commercial naval craft if LBMs were used to replace solid structural components. Weight reductions directly increase maneuverability, range, and fuel efficiency.
