Abstract:Al/Ti laminated composite features remarkable properties, such as low density, high strength, high stiffness and impact resistance, but its application has been limited because of the brittleness of Al3Ti. Its strength and toughness can be improved by introducing fibers and ceramic particles, which makes it have a broad application prospect in aerospace, weapons and armor. In this paper, the preparation methods of fibers and ceramic particles reinforced Al/Ti laminated composite were reviewed. The merit and dement of different preparation methods were compared. Besides, some feasible methods of boron carbide(B4C) reinforced Al/Ti laminated composite were proposed. The 0.2 mm thick B4C sheets reinforced Al/Ti laminated composite was prepared by vacuum hot pressing method. In this method, B4C sheets strengthen the matrix through directly receiving loads and deflecting crack by hardness gradient. Its impact toughness was 89 J/cm2 and bending strength was 756 MPa, it is increased by 51% and 38% respectively compared with the Al/Ti laminated matrix.
