ENERGY-ABSORBING SYSTEM, METHODS OF MANUFACTURING THEREOF AND ARTICLES COMPRISING THE SAME

摘要

Disclosed herein is an energy-absorbing device comprising a first layer; a second layer; the second layer being opposedly disposed to the first layer and in slideable communication with the first layer; the first layer and the second layer enclosing a space therebetween; the space being filled with a fluid that has a power law exponent a of at least about 1.3 when measured in half cell split Hopkinson bar using Equation (3) below; where |? w|max is a maximum shear stress, ? is a shear strain rate, U is a characteristic velocity of the striker wall, h is a thickness of the space, n is a power law dimensional factor that represents an energy dissipating property of the fluid.
