摘要
核壳结构能有效抑制Al基复合材料燃烧产生的大颗粒Al凝团,提升Al粉释能效率,改善Al粉的点火性能和燃烧释能特性。本研究从核壳结构Al基复合材料的特点出发,介绍了核壳结构Al基复合材料的研究进展,讨论了核壳结构Al基复合材料的常用制备方法,分析了不同组成对核壳结构Al基复合材料的燃烧性能、能量释放效率以及稳定性等方面的影响,并给出核壳结构Al基复合材料潜在的应用与发展方向:优化核壳结构制备技术并实现规模化生产的同时,调控包覆材料组分或在基体‑包覆层界面构筑功能化介层,可有效改善材料燃烧过程中的传质传热特性。
The core‑shell structure can effectively suppress the large aluminum(Al)agglomerates produced by combustion of Al‑matrix composites,enhance the energy release efficiency of Al powder,and improve its ignition performance and combustion energy release characteristics.Based on the characteristics of core‑shell structured Al‑matrix composites,an overview of the research progress was summarized.The commonly used preparation methods for core‑shell structured Al‑matrix composites were discussed,effects of different compositions on the combustion performance,energy release efficiency and stability of these com‑posites were analyzed.Furthermore,the potential applications and future development directions of core‑shell structured Al‑matrix composites were outlined.Optimizing the preparation techniques for core‑shell structures to achieve large‑scale production,regulating the composition of the coating materials or constructing functional interlayers at the matrix‑coating interface can effectively improve the mass and heat transfer characteristics during the combustion process of Al‑matrix composites.
