Abstract
The dynamic mechanical behaviors, failure mechanisms and anti-penetration performance of graphene reinforced Al/SiC composite were investigated in this paper. The mechanical behaviors of the material under strain rate 0.001~5 200 s-1 were obtained by static and dynamic compression tests and its strain rate effect was revealed. Furthermore, the fracture mechanisms of graphene reinforced Al/SiC composite under static and dynamic compressive loading were analyzed by optical and scanning electronic microscopy (SEM) observations. In addition, ballistic impact experiments were conducted to acquire the ballistic limit velocity and specific energy absorption of Q235A/graphene reinforced Al/SiC composite structure and Q235A steel plates with thicknesses ranging from 12 mm to 18 mm. The results indicated that the specific energy absorption of Q235A/graphene reinforced Al/SiC composite structure is 1.79 times that of Q235A steel plates with thicknesses ranging from 12 mm to 14 mm, and the specific energy absorption of graphene reinforced Al/SiC composite with the thickness of 34.10 mm is the same as the value of Q235A steel plate with the thickness of 16.70 mm.
