Public award description

THE PROPOSED RESEARCH AIMS TO DEVELOP A METAL MATRIX COMPOSITE (MMC) FABRIC THAT, WHEN COMBINED WITH ADDITIVE MANUFACTURING, WILL LEAD TO WEIGHT REDUCTION, INCREASED STRUCTURAL PERFORMANCE, AND REDUCE FABRICATION COSTS OF STRUCTURAL COMPONENTS WITHIN LAUNCH VEHICLES. THE APPROACH FOCUSES ON DEVELOPING A MMC FABRIC THAT WILL BE USED TO SELECTIVELY REINFORCE METALLIC COMPONENTS THAT ARE SUBJECTED TO MULTI-AXIAL FORCES WHILE IN SERVICE. THE MMC FABRIC IS ABLE TO BE APPLIED LIKE TRADITIONAL COMPOSITE PANELS (I.E. MULTIPLE PLIES AT DIFFERENT ORIENTATIONS) ALLOWING FOR A TAILORABLE REINFORCEMENT MATERIAL THAT CAN BE PLACED IN THE DIRECTION OF THE LOADING AXES. BY USING A SELECTIVE REINFORCEMENT ADDITIVE MANUFACTURING APPROACH, THE MMC FABRIC CAN BE PLACED STRATEGICALLY WITHIN AREAS OF HIGHSTRESSES AND ONLY IN THESE AREAS ALLOWING FOR COST SAVINGS AND WEIGHT REDUCTIONS DUE TO THE NEED OF LESS OF THE BASE MATERIAL IN THESE LOCATIONS. THE COMBINATION OF THE MMC FABRIC AND ADDITIVE MANUFACTURING WILL LEAD TO ENHANCED LIGHTWEIGHT, COST-EFFECTIVE STRUCTURES FOR VARIOUS APPLICATIONS.
