Measurements of dynamic properties of ballistic yarns using innovative testing devices

Abstract : This chapter highlights the influence of the dynamic characteristic of yarn on the ballistic performance of fabric submitted to impact. A brief review of existing research works done on the dynamic tensile test known as the Hopkinson bar, and more recently the Split Flying Bar, is presented. A new dynamic tensile test, called the Split Flying Mass, has been proposed, ensuring improvement in the tension of yarn, accuracy of measurement, and avoiding any slippage of yarn inside the clamping jaws during high-strain velocity tests. Experimental results conducted on para-aramid multifilament yarn have confirmed the increase of stiffness, revealing the specific dynamic deformation mode of high-performance yarns used in ballistic applications
