The failure mechanisms of SiC, B4C ceramic and the laminated SiC/BN composite armor under ballistic impacts of 5.8 mm steel bullet at 920 m/s were investigated by the finite element analysis and ballistic experiments. The results show that the fracture toughness of laminated SiC/BN ceramic with weak interfaces is 7.6 MPa·m1/2. The shear fractures of substrate and interlayer appear on the ballistic impact surface, and the delamination and folding fractures occur at the back. The more transgranular fractures occur when the interlayers increase, compared to the intergranular fractures. The shallower impact craters are generated when the thickness of the SiC substrate layers decreases along the impact direction. SiC/BN laminated ceramic has a better ballistic performance when the mass fraction of BN interlayer is 6.9%, and SiC and B4C block ceramics exhibit a better ballistic performance under multiple bullet impact condition.
