Laminated ballistic composite panels are an important part of hard-plate protective body armour and may be subjected to a wide variety of impact conditions depending on the projectile, impact velocity and armour construction. Kevlar fiber is the type of reinforcement most widely applied in these materials. Within the composites industry, woven, knitted and nonwoven reinforcements made of glass fiber, carbon fiber and aramid fibers are now widely accepted as being technical textile products. The applied of textile fabrics has generally provided a lower composite manufacturing cost and a higher damage tolerance. The highstrength, high-modulus Kevlar 49 fiber is widely used today because of its superior properties. Aramid fibers are known for their large hardness and resistance to penetration. Due to their toughness aramid fibers are used where high impenetrability is required, e.g. bulletproof vests, bike tyres, airplanes wings, and sport equipment. In this work, Kevlar nonwoven, obtained by cutting apart of the bulletproof, as used for reinforced polyester composites and kevlar fabrics manufacturing using handcraft process reinforced polyester will be tested using .38 weapons in close range in order to simulate a real situation (confrontation). The impact properties of the reinforcements will also be determined in the same situations and their behavior after tests are compared. The preliminary results after the gunshot test demonstrated the efficiency of the reinforcements in the ballistic for bulletproof vest and the developed fabrics. This fact evidences the feasibility of using the fabric as a ballistic application. The performance of the composite under gunshot test for polyester reinforced kevlar fabrics of the composite was performed in a 3 different sample. The results showed the effective action of the composites developed for application in shields. Independently of the reinforcement contents, all the composites presented resistance to shooting using caliber, 38 and 40. For the use of the caliber; 40 the material presented a very satisfactory result, considering the level of damage of this type of ammunition This result is indicative that the material developed can be used in shields.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
