This Small Business Innovation Research Phase I Project will develop a method for incorporating Single Walled Carbon Nanotubes (SWNT) into nylon fibers to act as reinforcement. This incorporation will be achieved by wrapping the SWNTs with a functionalized polymer that both allows the tubes to be dissolved in the solution containing the nylon precursors and acts as a load transferring conduit between the fiber matrix and the nanotubes in the final composite. The primary focus of this project is to optimize the SWNT/nylon matrix interaction in order to obtain the best load transfer properties and to direct the orientation of the SWNTs along the long axis of the nylon filaments in order to maximize the fiber's strength.The commercial application of this project will be in the aerospace industry. The high strength nylon fibers are expected to be used to construct flywheel rotors for airplanes and spacecraft that are capable of performing the dual functions of high density energy storage and control of gimbal and altitude.

这个小企业创新研究第一阶段项目将开发一种方法，将单壁碳纳米管（SWNT）纳入尼龙纤维作为增强材料。这种结合将通过用官能化聚合物包裹SWNT来实现，所述官能化聚合物既允许管溶解在含有尼龙前体的溶液中，又充当最终复合材料中的纤维基质和纳米管之间的负荷传递导管。本研究的主要目的是优化单壁碳纳米管/尼龙基体的相互作用，以获得最佳的载荷传递性能，并引导单壁碳纳米管沿着尼龙长丝的长轴取向，以最大限度地提高纤维的强度，本研究的商业应用将在航空航天工业中。高强度尼龙纤维有望用于制造飞机和航天器的飞轮转子，这些飞轮转子能够执行高密度能量存储和万向节和高度控制的双重功能。
