Four different grades of Silicon Carbides(SiC)from 3M were investigated with respect to their ballistic performance against tungsten alloy long rod projectile using module test method.This study provided a comparison of the ballistic performance of different SiC tiles under actual armour application conditions,i.e.a finite thickness backing,lateral confinement,and a thin cover plate.The metal-encapsulated ceramic armour modules were tested against 96g tungsten alloy long rod projectiles at a nominal velocity of 1250 m/s.A witness block was placed behind the test module.The ballistic performance was compared using the measurement of depth-of-penetration(DOP)in the witness blocks.The grades of SiC assessed were Grade F,Grade F-plus,Grade T,and Grade T-plus respectively where the F series were solid state sintered to achieve higher hardness while T series were liquid phase sintered to achieve higher fracture toughness.The plus indicated that the ceramics were post hot isostatic pressed(HIP)to achieve further densification and increased bending strength.The F series SiC performed better than T series while the post-HIP SiC performed better than their non-post HIP counterparts.The results showed that the increase in hardness and flexural strength of SiC enhanced the ballistic performance.
