Twaron® brand aromatic polyamide, commonly known as aramid fabric, was reinforced with a solution of graphene oxide (GO) followed by a heat treatment at 120 °C. The objective was to improve the ballistic properties of the material by increasing the friction coefficient of the fibers in the fabric. The GO produced by the modified Hummers method was characterized by Fourier transform infrared and Raman spectroscopy as well as by scanning electron microscopy (SEM) and atomic force microscopy. Both the as-received fabric and fabric coated with one and two filtrations of GO were characterized by the above-mentioned technique in addition to optical microscopy (OM). All samples were subjected to ballistic tests with 9 mm ammunition. The energy absorbed by the materials was calculated from the values ​​of impact velocities and residual obtained by Doppler radar. The type of failure was characterized by means of SEM and OM visual analysis. The results show a better resistive force of the two filtrations GO coated fabric, up to 50%, when compared to the plain as-received fabric.

Twaron®品牌的芳香族聚酰胺（通常称为芳纶织物）用氧化石墨烯（GO）溶液增强，然后在120°C下进行热处理。目的是通过增加织物中纤维的摩擦系数来改善材料的弹道性能。通过改进的Hummers方法生产的GO通过傅里叶变换红外和拉曼光谱以及扫描电子显微镜（SEM）和原子力显微镜进行表征。除了光学显微镜（OM）以外，还通过上述技术对原样织物和涂覆有GO的一次和两次过滤的织物进行了表征。所有样品均经过9毫米弹药的弹道测试。材料的吸收能量是根据多普勒雷达获得的撞击速度和残差值计算得出的。故障类型通过SEM和OM视觉分析来表征。结果显示，与原样的原始织物相比，两次过滤的GO涂层织物的抵抗力更好，高达50％。
