Ballistic Properties of Three-dimensional Woven Fabrics Under Angular Impacts
This work is aimed to clarify the protection ability of three-dimensional(3D)woven fabrics when they are subjec-ted to oblique impacts,and to gain a deeper understanding of the ballistic mechanism and protection performance of three-di-mensional woven fabric structures under the effect of different impact angles.In this paper,the 3D three-dimensional orthog-onal through-the-thickness(3D OTT)interlock woven fabric is considered,and a finite element model at the fine yarn lev-el is constructed with the help of the finite element solver(ABAQUS/Explicit),which analyses the damage morphology,stress distribution and energy absorption of the fabric under the projectile impact.It was found that the residual velocity was the highest under positive impact,which was 12.43%and 14.61%higher than the two oblique impacts,respectively.In the event of an oblique impact,3D OTT multilayer fabrics experience a large number of yarn pull-outs and contribute to the deeper involvement of the yarns in resisting the projectile impact process,increasing the total amount of energy absorbed by a-bout 13%.The study will deepen the further understanding of the ballistic protection performance of 3D woven fabrics and help in the development of new flexible protective materials.
