“…Because of these unique and interesting features, B 4 C is used in nuclear reactors, ballistic armors, abrasive materials, semiconductors, etc. [9][10][11][12]. There are various methods for the synthesis of boron carbide, but the production of this material at low temperatures is preferred [13][14][15].…”

In this article, the impact of different B4C synthesis methods on the amount of residual carbon and the final morphology of the prepared ceramic particles was investigated. The main materials for the synthesis of B4C were glucose and boric acid, and the effects of adding tartaric acid and performing mechanical activation were studied. For this purpose, two methods of carbon dissolution and boron carbide oxidation were used to determine the amount of residual carbon in the ceramic products. The results of the investigations on the sample synthesized in optimal conditions showed that if additives and mechanical activation are not used, about 7 wt% of carbon will remain in the synthesized powder. The amount of carbon decreased to 5.7 wt% with mechanical activation, but the best result was obtained with the addition of tartaric acid, in which the amount of impurity dropped to 3.3 wt%. Finally, the size and morphology of B4C particles and carbon impurities were observed and compared using a scanning electron microscope.

“…This material has high hardness and can resist the initial impact of the projectile and damage it [6]. Modern ballistic vests are made from advanced ceramics, where the most common are alumina (Al2O3), silicon carbide (SiC), and boron carbide (B4C) [7,8], in addition to being reinforced with fabric fibers and/or natural fibers [9][10][11][12]. Three factors make ballistic armor efficient: mobility, penetration resistance, and high impact absorption.…”

This article explores the ballistic and mechanical performance of HDPE matrix composites reinforced with alumina and silicon carbide particles, to be used as lightweight body armor. After processing, the composites were evaluated by tensile tests, Izod impact, and Shore D hardness. In addition, depth of penetration (DOP) and energy absorption tests were performed with chronograph simulating .22 ammunition in the ballistic test. Samples A80 and A70 had the lowest DOP result (15.98 and 17.98 mm respectively) indicating that these samples had the best ballistic performance. Mechanical tests performed on samples A00, A40, A50, and A60 showed that the deformation and tensile strength were reduced with the addition of ceramic reinforcement. Impact resistance also decreased. Shore D hardness showed a considerable increase in hardness of A40, A50, and A60 compared to A00.

“…From 1960s on, studies on light ceramic armor and polymeric materials started to gather relevance in the use of body armor plates made up with alumina (Al 2 O 3 ), silicon carbide (SiC) and boron carbide (B 4 C), prevailing in hard armors systems [ 7 , 8 , 9 , 10 ], due to high impact strength [ 11 , 12 ]. At the same time, soft armors emerged based on high-performance polymeric fabrics and polymer matrix composites (PMC) in a ballistic application for lighter gears.…”

Fabric Impregnation with Shear Thickening Fluid for Ballistic Armor Polymer Composites: An Updated Overview

As destructive power of firearms raises over the years, ballistic armors are in continuous need of enhancement. For soft armors, this improvement is invariably related to the increase of stacked layers of high-strength fiber fabrics, which potentially restrains wearer mobility. A different solution was created in the early 2000s, when a research work proposed a new treatment of the ballistic panels with non-Newtonian colloidal shear thickening fluid (STF), in view of weight decreasing with strength reinforcement and cost-effective production. Since then, databases reveal a surge in publications generally pointing to acceptable features under ballistic impact by exploring different conditions of the materials adopted. As a result, several works have not been covered in recent reviews for a wider discussion of their methodologies and results, which could be a barrier to a deeper understanding of the behavior of STF-impregnated fabrics. Therefore, the present work aims to overview the unexplored state-of-art on the effectiveness of STF addition to high-strength fabrics for ballistic applications to compile achievements regarding the ballistic strength of this novel material through different parameters. From the screened papers, SiO2, Polyethylene glycol (PEG) 200 and 400, and Aramid are extensively being incorporated into the STF/Fabric composites. Besides, parameters such as initial and residual velocity, energy absorbed, ballistic limit, and back face signature are common metrics for a comprehensive analysis of the ballistic performance of the material. The overview also points to a promising application of natural fiber fabrics and auxetic fabrics with STF fluids, as well as the demand for the adoption of new materials and more homogeneous ballistic test parameters. Finally, the work emphasizes that the ballistic application for STF-impregnated fabric based on NIJ standards is feasible for several conditions.
