This Small Business Innovation Research (SBIR) Phase I project proposes to develop copper-graphite and copper-SiC composites with 40-50V% reinforcement loading using a microencapsulated powder metallurgy process. These microencapsulated powders will be combined with injection molding for the low cost fabrication of highly complex parts such as a finner radiator. The project will demonstrate an economical solution to metal matrix composite microstructural control and reliability problems, and will develop a new, high performance class of materials able to be used with injection molding and rapid prototyping equipment.The broader impacts from this technology would be first demonstration of injection molded metal matrix composites, opening up and entirely new range of properties/cost for performance materials. The combination of high thermal performance and low cost solves a number of problems with waste heat management in automotive/transportation, space vehicle, heating and climate control, as well as electronics and power conditioning applications. Furthermore, the ability to injection mold highly loaded metal matrix composites will be immediately translatable into structural, optical, and wear/mechanical components.

该小型企业创新研究（SBIR）第一阶段项目提出使用微胶囊粉末冶金工艺开发具有40-50V%增强负载的铜-石墨和铜-SiC复合材料。这些微胶囊化粉末将与注射成型相结合，以低成本制造高度复杂的零件，例如鳍片散热器。该项目将为金属基复合材料的微观结构控制和可靠性问题提供一种经济的解决方案，并将开发一种能够与注塑成型和快速成型设备一起使用的新型高性能材料。该技术的更广泛影响将是首次展示注塑成型金属基复合材料，开辟性能材料的全新性能/成本范围。高热性能和低成本的结合解决了汽车/运输、航天器、加热和气候控制以及电子和功率调节应用中的废热管理的许多问题。此外，注塑高负载金属基复合材料的能力将立即转化为结构，光学和磨损/机械部件。
