Abstract

Triton Systems Inc. proposes an innovative single step method for fabricating low density, high performance, in-situ nano metal matrix composite (MMC) structural foam materials to net-shape. Triton Systems is teamed with Laser Fare on the proposed effort to enhance a novel solid freeform fabrication process known as Laser Engineered Net Shaping (LENS) technology to produce nano TMC foam structural materials. The proposed program will take advantage of Triton's recent advancements in laser processing TMC's, which have shown significant property enhancements compared with monolithic metals and alloys, to further improve the specific properties of the foam structure. The proposed technology will enable net shape manufacture of foam structures in a single fabrication step and allow the structure to be engineered (as opposed to the random nature of current metallic foams) to take maximum advantage of the material for a given application. The proposed material and process technology will enable the design and manufacture of structural foam parts to be optimized for a given application (in terms of weight, strength, energy absorption, etc.) and decrease cost by eliminating expensive tooling. BENEFITS: The proposed materials and process technology will enable the affordable manufacture of high performance engineered structural foams designed for specific applications. Potential applications include energy absorbing components such as armor for the military and automobile bumpers for civilian use and high temperature combustion engine components.
