High specific strength and stiffness properties of carbon fiber composite cylinders make them an ideal material for internal pressure and blast applications. While previous research investigates failure loading and modes on composite cylinders, additional studies display the benefits of carbon nanotube (CNT) reinforcement in various applications. However, limited research has been conducted on the effects of CNT reinforcement with respect to internal pressure loading. CNT reinforcement in composite cylinders could result in significant improvements in specific strength and stiffness, allowing for higher internal pressure loading. In this work, using wet winding, CNTs were distributed into resin and then introduced into a fiber matrix. Composite cylinders were produced at various winding angles. These cylinders were tested and compared to cylinders without CNT reinforcement. This research focuses on the specific strength and stiffness of CNT-reinforced cylinders.
