| Abstract: | In order to investigate the absorbing energy character of functionally graded plate of GFRP/CFRP with different GFRP ply proportion,a series of ballistic impact tests are performed using weight 80 g and diameter 23 mm bullets with a speed of about 70m/s.Impact damage and residual compressive strength are analysed,and the maximal impact damage area is found on the mid layer with a C-scan device.With GFRP ply proportion increased,the absorbing energy character of functionally graded plates is enhanced.By comparing deformation of back panels,it is found that,the functionally graded plate with 5% GFRP is suited to be made to ballproof armor of structure,but with 30% GFRP is well suited to be human protective armor. |
