AbstractORBITEC and the Milwaukee School of Engineering (MSOE) propose to develop functionally graded metallic lattice components for use in advanced rocket propulsion systems. The FGMLC material will utilize an internal intertwined lattice structure to join different constituents of the composite material. This lattice structure will allow a designed gradation from one material to another while maintaining each materials properties. The FGMLC will utilize a high-heat flux metallic material for the hot-side surface. This material will be graded to a high-strength, light weight metallic materials on the outer surface of the component. The FGMLC offers several advantages over conventional graded materials. The mature FGMLC is expected to offer a low-cost, lightweight, long life, elegant design for high heat flux applications. The Phase I effort will involve selection of candidate materials and manufacturing processes, fabrication of FGMLC test samples, development of a laboratory test fixture to evaluate the performance of FGMLC prototype components under simulated operating conditions, mechanical testing of FGMLC samples, evaluation of component behavior and performance under test conditions, and development of Phase II fabrication and test plans. This proposal responds to Topic SB082-007, which requests new materials and processes that provide revolutionary capability to DoD platforms and weapon systems.
