| 摘要: |
| 金属基复合材料(MMCs)由于其优异的性能,在空天、交通、电子、能源等领域的应用中具有不可替代的作用。随着科学技术的发展,单一高性能的金属基复合材料常不能满足越来越复杂的使役条件,亟需发展综合性能优异、多功能协同的新型金属基复合材料。然而,不同性能之间由于多种增强机制耦合,其解耦调控困难,使得它们呈现倒置关系。近年来,通过调控增强体在金属基体中的空间分布,即对复合构型开展研究,充分发挥复合材料的可设计性,最终实现金属基复合材料的多性能之间的协同,已成为该领域发展的重要趋势。本文在本研究团队前期关于金属材料构型化复合的研究基础上,以纳米碳/铜基复合材料为典型范例,对我们在该类新型材料研究中通过复合构型设计实现结构-功能一体化的最新进展,即“微纳砖砌”构型对强度-塑韧性-导电性能的协同进行了总结和介绍,并对该领域的发展趋势进行了展望。 |

| Abstract: |
| Metal matrix composites (MMCs) play an irreplaceable role in the fields of aeronautics and astronautics, transportation, electronics, and energy due to their exceptional properties. With the development of science and technology, MMCs with single high performance cannot meet the requirements of more and more complex service conditions, and it is urgent to develop new MMCs with outstanding comprehensive properties and multifunction synergy. However, various enhancing mechanisms for different properties are coupled and difficult to be decoupled, which results in multiple trade-off in many properties. In recent years, regulating the spatial arrangement of reinforcement in metal matrix has been an important tendency for the development of MMCs, where studies focuson composite architecture and utilize the designability of composite materials to realize good balances between various properties in MMCs. In this paper, based on our investigation on the architecture design of MMCs, by taking the nanocarbon reinforced copper matrix composites as a typical example,our recent progress on achieving the integration between structural and functional properties by architecture design in these new materials is introduced, i.e., the synergy between mechanical strength-toughness and ductility-electrical conductivity realized by an architecture of “brick-and-mortar” at micro-/nano-scale. In addition, the development trend in this field is put forward. |
