Abstract Networked fabrics are a type of three-dimensional multilayer fabrics having predetermined interconnections between layers by combining yarns from two adjacent sublayers into one. This paper reports the research on the influence of structural parameters on the ballistic performance of networked fabrics using finite element analysis in parallel with experiment. The widths of separate and combined sections are found to affect the energy absorption (EA) of regular networked fabrics against high-velocity impact. Separate sections of networked fabrics generally outperform combined sections. The optimal width of the separate section is around 9.5 cm for both dense and loose networked fabrics when impacted at the separate section. The optimal width of combined section decreases from 2.38 cm to 1.15 cm with the decrease of weave density in this area. For the studied structural parameters, highest EAs of dense and loose networked fabrics are around 13.3% and 17.1% higher than those of their counterpart layups of dense and loose plain-woven fabrics, respectively. These findings suggest networked fabrics could be engineered to improve the ballistic performance of flexible fabrics. Keywords Finite element modelling . 3D networked fabric . Ballistic impact
1 Introduction Fabrics made with high-performance materials such as para-aramid and UHMWPE are widely used for soft body armours. During the past decades, a lot of experiments and theoretical work have been conducted to understand the impact behaviour of soft body armours, which were reviewed in [1–3]. Flexible armour undergoes minimal transverse deformation and spreads

impact energy over an area to provide protection. When a projectile impacts into a protective fabric, the kinetic energy of the projectile is converted and dissipated as kinetic energy of the fabric, strain energy of the yarns, and energy consumed due to frictional sliding. The ballistic performance of a fabric assembly depends on its ability to absorb and convert energy through impact interaction and to dissipate energy quickly to a large area to avoid early local failure. This ability is affected by the energy dissipation performance of the fibres, fabric weave construction, number of fabric layers and boundary condition, and by the characteristics of the friction, projectile shape and trajectory. Plain and basket woven fabrics are most widely used structures for ballistic protection because their high intersection ratios are recognised advantageous to transfer impact energy to the
