Table 1.2 Comparison of mechanical properties of a typical 3D woven composite and an equivalent multilayer 2D woven fabric composite...

Figure 13.12 presents the energy absorption of six 3D Kevlar fabrics with comparison to the 2D plain weave fabric, which is widely used for body amour production for police and military personnel. It was foimd that (a) 3D honeycomb fabrics and the same layer 2D plain fabric The two- and four-layered 3D fabrics performed better than the assembly with the same layer 2D plain woven fabric of similar yam density. The twolayered fabric with lower yam density performed less well than the one with higher yam density, (b) AU the 2D woven fabrics have the ability to absorb more projectile impact energy compared to the three 3D angle-interlock fabrics. 

D woven fabrics have significant impact in the application for protective clothing. They can be made through different ways depending on the end use. Their advanced performance in comparison to 2D woven fabrics can be summarised in the following aspects ... 

D weaving The weft yarns are inserted over and under the multiple layers of warp yams. This process yields thicker woven structures than in 2D weaving where only one single layer of warp is used. 3D woven preforms have higher strength in the thickness direction than the 2D woven fabrics however, their strength decreases in the in-plane directions due to the fiber crimp.
