SBIR Phase I: Injection Molded Copper Composites for High K Structures

这个小企业创新研究（SBIR）第一阶段项目建议使用微胶囊粉末冶金工艺开发40-50V%增强载荷的铜石墨和铜sic复合材料。这些微胶囊粉末将与注射成型相结合，以低成本制造高度复杂的部件，如鳍片散热器。该项目将展示金属基复合材料微观结构控制和可靠性问题的经济解决方案，并将开发一种新的高性能材料，可用于注射成型和快速成型设备。这项技术的广泛影响将是首次展示注塑金属基复合材料，为高性能材料开辟了全新的性能/成本范围。高热性能和低成本的结合解决了汽车/运输，太空飞行器，加热和气候控制以及电子和电力调节应用中的废热管理问题。此外，注塑高负荷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。

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.
