摘要:

連續纖維增強的金屬�步饘匍g化合物層狀復合材料兼具高強度、高模量和良好的韌性等優異性能，逐漸成為國內外學者的研究重點。這種復合材料包含龐雜的體系、復雜的結構和性能表現，因此有必要對其制備技術、結構特征和綜合性能開展深入的研究。以纖維增強Ti/Al3Ti層狀復合材料為對象，系統地綜述了其研究現狀。首先介紹了Ti/Al3Ti等層狀復合材料的制備技術，并著重探討了真空熱壓燒結和超聲波固結輔助熱壓燒結兩種方法在制備纖維增強Ti/Al3Ti層狀復合材料方面的優缺點；然后圍繞陶瓷纖維、金屬纖維和形狀記憶合金纖維增強的Ti/Al3Ti層狀復合材料的組織結構、力學性能和功能特性進行了述評；隨后闡述了纖維增強Ti/Al3Ti層狀復合材料中各種纖維的強韌化機制；最后結合現有研究中存在的主要問題，對連續纖維增強金屬-金屬間化合物層狀復合材料未來的發展方向進行了展望。

Abstract:

Continuous fiber-reinforced metal-intermetallic-laminate composites (FR-MILCs) have been the research focus of laminate materials due to their high strength, high modulus and superior toughness. The FR-MILCs possess complex material systems, complicated microstructures and various performance indexes. Thus, it is of significance to investigate the preparation technology, microstructure and comprehensive properties of these composites. In this paper, the research status of fiber-reinforced Ti/Al3Ti laminate composites is systematically reviewed. Firstly, the preparation technology of laminate composites such as Ti/Al3Ti is introduced, and the advantages and disadvantages of vacuum hot pressing sintering and ultrasonic consolidation assisted hot pressing sintering in preparing fiber-reinforced Ti/Al3Ti laminate composites are introduced. Then, the microstructure, mechanical properties and functional properties of Ti/Al3Ti laminate composites reinforced by ceramic fibers, metal fibers and shape memory alloy fibers are elaborated, respectively. Besides, the strengthening and toughening mechanisms of various fibers in fiber-reinforced Ti/Al3Ti laminate composites are analyzed. Finally, combined with the main problems in the existing research, the future development direction of continuous FR-MILCs is prospected.
