$Ballistic impact fracture behaviour of continuous fibre reinforced al-matrix composites$

Ballistic impact fracture behaviour of continuous fibre reinforced al-matrix composites

The materials response under high energy impact loads was studied using a gas gun. The projectiles were pins 1.2-1.5 mm in diameter and weighing 0.347-0.435 g. The projectile velocity was in the range 100–1300 m/s. The remnant load carrying capability of composite samples after high velocity impac...
