INVESTIGATION OF THE USE OF BORON NANO MATERIALS IN TEXTILE BASED BALISTING PRODUCTS

In recent years, nanomaterials and nanotechnology have become very effective in obtaining highly functional products. Boron works show that boron gives superior properties to materials and products. Boron is used to improve material performance such as thermal insulation, electrical conductivity, strength enhancement, processability improvement. It is evident that boron is a very important material, and its importance and nano-size boron particles are characteristic. Boron is used from automotive to machine, textile to health. The use of boron as boron carbide, boron nitride, aluminum borate and borohydride is found in various investigations. Boron carbide stands out with its high hardness value and lightness. Boroncarbide is used in the defense industry for the production of plates used as lightweight protective protective ballistic armor or vests. Boronnitride is hexagonal and cubic in structure, also known as white graphite because of its graphite resemblance. Boronnitride is the least dense material among ceramic materials (2.27 g / cm3) [1]. Boronnitrile nanofibers (BNNF) find applications in increasing the performance of high temperature ceramics. Aluminumborate (9Al2O3.2B2O3) is a material with high melting temperatures, low density, low thermal expansion coefficient and low friction resistance. Because of these properties, they are used as automotive, composite materials and electronic ceramic materials as oxygen resistant reinforcements [2]. Boronhydrides are the most stable and commercially available [3]. This material is used for bleaching paper clay, recovering precious metals such as gold, silver, etc. from the solutions; removal of heavy metals such as cadmium and mercury in waste water; are used in the production of chemicals. Boron is used as fiberglass in the textile sector due to its flame retardant property. In addition to this, it can be used in fabric dyeing and fabric finishing processes. Boron is used as matrix reinforcing reinforcements in the construction of composite materials with nano size shape and also as reinforcing element in the form of boron doped fibers. Use of boron materials in defense industry; protective textile products, protective vests and helmets [4,5,6,7]. In this study, it was aimed to strengthen the boron carbide nanoparticles to the aramid fabrics and to produce composite textile material to be used for vests, which can provide protection level III in the defense industry and to evaluate the ballistic performance of this composite textile product. Taking into consideration the lightness, price and performance indicators, it is aimed to reveal the optimum number of fabric coats and nano boron carbide ratio. In the study, a 200 g / m2 aramid fabric was selected and an experimental plan was developed in which the proportions of boroncarbide nanoparticles to be added to the composite resin were changed. The fabrics will be brought together on different floors to form a structure for protective vests. This composite textile structure will be subjected to ballistic tests with protection level III, and the performance of the product will be examined. The study will be carried out by applying optimization techniques from scientific research techniques.
