Development of scattering prevention sheet using high strength fiber fabric

Abstract

Concrete and metal pieces may scatter to the surroundings during demolition work. In some cases, this scattered material flies at high speed and has a risk of injuring a person. However, the curing sheet currently used in demolition work is mainly aimed at soundproofing and dustproofing, and it is not considered to prevent penetration of scattering matter at high speed. Therefore, in this research, we tried to develop a scattering prevention sheet using high strength fiber fabric. First, the penetration resistance performance of high-strength fiber fabric was investigated by using a projectile simulating a metal piece which may possibly scatter. It was revealed that the projectile shape influences the penetration resistance property of the high strength fiber fabric. In addition, it was clarified that the order of superposition is important when using high strength fiber fabrics in layers.
