The effect of projectile shapes on the ballistic impact failure of TROGAMID CX-7323 (CX) was examined. It was found that the failure behavior of CX changed with differing nose shapes of the impacting projectile. Conical, hemispherical and chisel-nosed projectiles generally showed ductile failure. As the projected area of the projectile increased, the material's ballistic performance was noticed to decrease. Although currently inconclusive, impact with right circular cylinder(s) (RCC) frequently caused brittle fracture in impacted samples.
