Experimental research on tungsten alloy spherical fragments penetrating into carbon fiber target plate

A ballistic projectile launching device was used to study the penetration behaviors of tungsten alloy spherical fragments various diameters into carbon fiber composite target plates different thicknesses. Based on test results, we obtained relationship between ultimate velocity, plate thickness, and fragment diameter as well energy incident velocity. Using dimensional analysis, a formula relating velocity energy, which showed good agreement with experimental values. We also analyzed main fracture mode absorption mechanism under high-velocity impacts spheres investigated damage modes at velocities during impact.
