Evaluation of the compressive and anti-penetration properties of Ti-Al3Ti-Al laminated composites

Abstract

In order to further improve the mechanical properties of Ti-Al3Ti laminated composites, the endothermic semisolid reaction was used to fabricate Ti-Al3Ti-Al laminated composites, and the quasi-static compressive test, dynamic compressive test, and the ballistic penetration test were conducted on these composites. The results showed that the compressive strength and failure strain of Ti-Al3Ti-Al laminated composites prepared at 660°C are 1432 MPa and 35%, respectively. The dynamic response of these composites has obvious strain rate effect, and the crack grows in the shape of “Z.” The V50 of Ti-Al3Ti-Al targets is 509 m s−1. To sum up, Ti-Al3Ti-Al laminated composites have better mechanical properties and anti-penetration properties compared to Ti-Al3Ti laminated composites.
