Design theory and anti-ballistic effect simulation of dual phase hybrid functionally graded ceramic composite armor

Abstract

Abstract Functional gradient structure design is one way to improve the anti-ballistic performance of ceramic composite armors. In this paper, the design theory of dual phase hybrid functionally graded ceramics is established. Through the finite element simulation of the anti-ballistic behaviour, three structural effects of dual phase hybrid functionally graded ceramics composite armor are studied: monolithic ceramics (MC), unidirectional functionally graded ceramics (UFGC) and bidirectional functionally graded ceramics (BFGC). The ceramics structure of composite armor is optimized. The simulation results of the optimized structure of unidirectional and bidirectional functionally graded ceramics are better than that of monolithic ceramics, and the weight is lighter. This research can provide theoretical support for the design of functionally graded ceramic composite armor.
