To fabricate the comb target with low damping and high performance-price ratio,0.03-{0.1 mm} thickness aluminum foi l used as the conducting medium,the upper and lower surfaces covered with 0.5-1 mm thickness plastic film,after four processes of thrusting,laminating,punching and cu tting,a 500 mm×{500 mm} comb target is fabricated.A 155-mm projectile expl osiv e pow er test is conducted.Using the newly fabricated comb target,the measured initi al velocity of the fragment is 2 070 m/s.Th e test results show that the new comb target is of high test pre cision,small damping,low cost and high production efficiency,and it can measure th e 2 mm×2 m m fragment's initial velocity.
