JAMCORP proposes to develop MicroPerf Lattice Block Material using progressive coining dies to increase production rates above the current method of photolithography. MicroPerf is an octet truss based material with high strength to weight. MicroPerf is manufactured by attaching alternate layers of flat and corrugated sheet metal with much of the material removed. The layers are resistance welded forming a very stiff, very light sheet steel replacement. MicroPerf Lattice Block Material is a direct, high strength replacement for many sheet steel applications. By increasing the strength and stiffnees of sheet steel, MicroPerf will reduce the expense, complexity, and development time of the internal structures currently required in vehicles. Coining die production will yield a higher quality material at a lower cost per sheet of LBM.
