Ramie (Boehmeria nivea) is one of the strongest natural cellulose fibers. Optimizing abundant resources ramie as a candidate materials used for reinforcing in polymeric composite material is a must to obtained high-performance natural fibers reinforced polymer especially for bulletproof panel or high-impact flexibility safer structures. Ramie woven was treated using common chemical solvents that were ethanol, methyl ethyl ketone, acetone, and silane as coupling agent. Composite panels were made by hand lay-up process with epoxy as a matrix. These prototype bulletproof panels were to be believed lighter in weight and much lower economic cost than conventional bulletproof panels made from ceramic plate, Kevlar/aramid composite, and steel-based material as a popular today in military standard antiballistic equipments. From the bullet testing result, it showed that panel could be able to resist the penetration of high-impact projectile for level II with some fractures phenomenon. Level IV ballistic testing showed that all prototype panel could not resist the high-impact velocity of the projectile yet. It was found that ramie fibers have sufficient breaking strength and toughness for level II bullet testing, although still needs improvements to optimize process parameters to meet a very high military standard and application
