Research on the relationship between viscoelasticity and shock insulation of warp knitted spacer fabrics
Warp-knitted spacer fabric commonly used in the impact protection was selected as test materials to study the relationship between viscoelasticity and the performance of shock isolation.A damping test platform was set to test different specifications of warp-knitted spacer fabric,aiming to determine compression elastic modulus,damping ratio,and the residual impact load under different impact speed.Based on the experimental results analysis,for both viscous and elastic warp-knitted spacer fabrics,there was no clear correlation between viscous or elastic as individual indicators and isolation performance.Accordingly,using viscosity-to-elasticity ratio to characterize the relationship is propesed,and it is found that viscosity-to-elasticity ratio has a great influence on the shock isolation performance improved within a certain range.
