Recently, the shatterproof technology designed for the safety of the operators and the guard of adjacent building from high-speed projectile fragments, such as concrete, reinforcing steel and bolt, was required in demolish work. In this study, the evaluation of protective properties against high-speed projectile by using high strength fiber fabric was experimentally investigated using the quasi-static and impact penetration tests. The specimen made of the polyester (#300 and #800) and aramid fiver fabrics. A quasi-static penetration test was performed at the displacement rate of 5 mm/min using an Instron universal testing machine. An impact penetration test was carried out using a large-scale launching system with sabot separation part. The jig in contact with specimen was steel ball with diameter of 34.5 mm. In the quasi-static penetration test, the load was increased with increasing the displacement. It was cleared that the ratio of maximum penetration load to tensile strength of fabric of #300 was accorded with that of #800.
