Since the emergence of the first armoured vehicles on battlefields, armour shield was mainly centred on conventional metallic materials, widespread solutions nowadays. For a long time, weight reduction in armoured protection, which represents the largest part of the vehicle's overall weight, has been the key parameter for vehicle manufacturers looking forward to optimizing fuel consumption, thus increasing the payload and offering increased manoeuvrability to vehicles. The solution generally developed is a combination between those metallic plates and materials lighter than the current steel armour. In this context, the hybridization of some well-known ballistic alloys with textile composite materials appears to be a high-potential solution for armour-plated protection. Indeed, used as a backing, textile composite materials present some worthwhile properties such as having a very low density compared with steel and good behaviour in terms of ballistic efficiency. The use of a textile composite backing allows a reduction in the thickness of the metal plate by a few millimetres, which has a huge impact on the total protection weight. The difficulty of this hybridization is, of course, to reduce the total mass of the protection solution as cautiously as possible while ensuring the safety of the vehicle. The textile composite backing is also efficient in containing the pieces of shrapnel, which might break loose from the metal plate during impact. However, observations from today's military theatres of operation reveal that the spectrum of armoured

In today’s scenario, numerous studies have shown a great interest on 3D woven structures like 3D warp interlock fabric as a fibre reinforcement for composite material to provide a better impact than 2D laminated fabrics with unlinked structures in the thickness. The impact energy absorption capacity depends on different and independent parameters, including the shape and speed of the projectile, the type of fibrous structure (geometry), the type and nature of the threads (raw material, linear density, and twisting value), and the type of impregnation of the composite material. As part of our research work on hard impact protection solutions, the interest of textile composite structures, in particular those integrating 3D warp interlock fabrics, has been revealed. Based on the result, protection solutions with such fabric structure revealed larger dynamic deformation capacity for absorbing the impact energy as compared with not only a ceramic material facing a 12.7 mm ammunition (mass 43 g) at 610 m/s but also those solutions made with metallic materials facing a FSP (diameter 20 mm, mass 54 g) at 630 m/s and 1600 m/s. For each of these different threats, a specific type of composite material has to be used. These composite material solutions are mainly defined to respond to the appropriate mode of impact behaviour.
