Dynamic impact protective body armour



Personal body armour is one of the most important pieces of equipment to protect human beings from various critical and fatal injuries. In today’s modern world, various organizations including law enforcement and security service have made it mandatory for their personnel to wear personal protection system while on field duty. However, the systems should comprise an improved ballistic performance, light-weighted, flexible as well as comfortable panel not only to be accepted with a wider range but also for effective performances of the consumer. Generally, the overall performances of the protective body armour could be affected by various parameters including armour design techniques, type of materials used and finishing of the panels. The current paper aims to critically review state-of-art for armour panel design techniques and the different perspective body armour materials. The paper starts by discussing the different body armour and its category. Later, the different states of technology for armour panel design (mostly for women), its problems and the possible solutions will be cited. Later, the commonly used different polymeric fibrous and the future possible advanced materials including carbon nanotube (CNT), Graphene CNT and shear thickening fluids (STFs) treated materials for developing the reinforced body armour panel will be discussed. The authors believe that this paper will enlighten useful guidelines and procedures about the different panel design techniques and current and promising future materials for researchers, designers, engineers and manufacturers working on the impact resistance body armour field.To get more news about bullet proof vests, you can visit bulletproofboxs.com official website.

In general, ballistic and sharp weapon protecting clothing also called personal armour can be worn by law reinforcement police, military and other civilian such as journalist, security guards to protect themselves from ballistic, spike, knife and stab threats etc. [1]. Its developmental history is as old as the evolution of mankind and evolved from time to time to protect different parts of the body. It includes the torso (body armour), the cranium (helmets), and the face & eye (visors, glasses, goggles and pelvic & neck protection garments [2]. In today’s scenario, many law enforcement agencies have made it mandatory for their officers to wear ballistic protective vests while on duty.
Even though various countries make the ballistic vest an obligatory outwears for their officers, however, many personnel did not feel comfortable to wear the vests while on duty. This is because most of the developed vests are made with either heavy or/and rigid materials to achieve better ballistic impact protections for higher threat level (NIJ Level III and IV). Unless it is designed with lightweight, flexible, well-fitted along with good ballistic resistance performances, wearing heavy and inflexible body armour for an extended period could generate excessive heat and bring less mobility [[3], [4], [5]]. For the last many decades, various materials from felt to metal, fabric to composite, nanomaterials and further bioinspired materials in its biomimetic conditions were exploited for the developments of body armour systems [6].
Currently, various researchers and body armour developers have involved and continuously working intensively on the new generation and innovative different ballistic fibres, ballistic fabrics, panel layers parameters and body armour design techniques not only to improve the overall performance but also to realize the requirement of a modern military operation, technology-driven war tactics and current terror threats [[7], [8], [9]]. Meanwhile, the involvement and participation of women workforces have been also drastically increased for the last few decades in the field of law enforcement, privet security and military forces across the globe [10,11]. Even though the numbers of women personnel are significant, they were fitted with either unisex or smaller size of male-based body armour for so long. This fitting of male-based armour for women personnel’s is not acceptable due to not only the physiological differences but also imposes the disproportionate on fitness, comfort, and worse ballistic protection causing functional sacrifices. Even, unlike the male, designing of women soft body armour encounter problems and need special attention due to its unique curvilinear body shape.
Moreover, the effectiveness of the women soft body armour related to ballistic impact performance, fitness and comfort depend on the various factors including type of ballistic material, material finishing and garment designing techniques. Considering the above problems, various researchers and body armour manufacturer have been working on unique design techniques and appropriate materials to develop women soft body armour based on their morphological shape. However, most of such kinds of researches findings are funded either privately to improve the marketability of specific products or patented by intelligence security authorities or individuals. This makes those research output unreachable and secret for the wider audiences who are working and making research in the field. Moreover, despite various research studies on the field of ballistic material and design of body armour, it is also acknowledged that a detail and systematic review dealing with women soft body armour design, ballistic material and its testing methodologies have not been well investigated and documented. For this reason, it is very difficult to find the current situation and the specific gap in the field for further analyzing, investigations and improvement.
