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.
