Abstract
A projectile trap is provided having three groups of suspended polyurethane sheets. The polyurethane sheets are processed so as to have high cut and tear resistance properties and low rebound properties. The hardness of the polyurethane sheets increases from the first group of sheets at the front of the bullet trap, which are first contacted by a bullet, to the third group of polyurethane sheets at the rear of the bullet trap. The polyurethane sheets are suspended in the bullet trap by a keying arrangement which ensures that individual polyurethane sheets of a particular group may only be placed at specific locations in the bullet trap.
