Abstract

Within the munitions industry, there has been a notable emphasis on the development of cost-effective, easily wearable, and biocompatible flak armor. The rising popularity of fiber-reinforced polymer biocomposite technology, particularly employing natural fibers, stems from its eco-friendliness and cost-effectiveness, which holds particular significance in today's defense sector. As firearm technology advances rapidly, it necessitates a concurrent focus on enhancing personal protective equipment, with bulletproof vests being a commonly utilized safeguard. These vests play a critical role in mitigating the impact of ballistic threats on individuals. This study is dedicated to the investigation of natural fiber biocomposite materials for their applicability in bulletproof vests, addressing their mechanical properties and suitability for such a vital protective role.

Abstract

The optical glass used in LiDAR applications requires specific characteristics, including high strength and low porosity, to achieve optimal performance. One promising approach is the incorporation of alumina fibers as a reinforcement in the optical glass matrix. This research investigates the potential of alumina fibers in enhancing strength and reducing porosity in optical glass used in LiDAR applications. Alumina fibers are introduced into the optical glass matrix through a precise manufacturing process. The results of mechanical testing indicate that the addition of alumina fibers significantly increases the strength of the optical glass, making it more resistant to mechanical pressure that may occur during the use of LiDAR in challenging environments.

Abstract

Throughout the history of warfare, the need for hard military equipment could not be replaced even in prehistoric times. Humans mostly used iron helmets or steel armor to protect the human body from attackers. In the era of World War 1, humans created tanks with thick armor and this technology is still widely used. In its development, after the Vietnam war, the need for advanced materials that can absorb radar radio waves to make military equipment undetectable by radar in the current war is very high, this can be seen in many stealth equipment programs such as the joint strikefighter, Nighthawk, Stealth Ship and many more. Departing from this motivation, further discussion is needed about radar-absorbing materials in this case cerium oxide into boron carbide as a material that is not only super hard but also stealth. In this journal, several literatures are processed to hypothesize whether the doping technique of the two materials will become a promising advanced military material without reducing its strength for further experiments. After the literature study, it can be concluded that there are still additional materials to create super hard and stealth materials such as carbon nanofiber.
