Low-density, high strength composites play a critical role in a wide range of technological areas including aerospace, defense, sports, transportation, and renewable energy. One of the most important classes of low-density materials is polymer matrix composites, which are now used as primary structural materials for large airliners, and in other applications, such as wind turbines and ship structures. The use of nanostructured reinforcements in composites has been shown to improve strength, resulting in structural weight reduction, thereby leading to fuel savings and reduced ecological impact. There is an increasing interest and a strong need for nanomanufacturing technologies for making the nanostructured reinforcement materials and their composites that are scalable in throughput and quantity. Through this Scalable NanoManufacturing (SNM) award, an interdisciplinary research team will work with industry to develop a continuous nanomanufacturing process to fabricate light-weight, high-strength structural composites. Nanometer thick carbon nanotube fabric will be wrapped around individual fibers to create "fuzzy" carbon fibers to enhance their bonding strength with the surrounding polymer. The nanostructured composites will be tested to evaluate their performance under service environments. The use of the carbon nanotube fabric wrapped carbon fiber composites can potentially reduce the structural weight of aircraft, increase energy efficiency and reduce travel time. This project will make an important contribution to the continued success of the NanoExplorer program. A large number of high school and college students will be involved in all aspects of this multi-disciplinary project. Efforts will be made to recruit students from minority and under-represented groups. In this project, a continuous nanomanufacturing line will be designed, built and assembled to wrap individual fibers with carbon nanotube fabric, without degrading in-plane carbon fiber properties. The concept of "false twist" will be employed to scale-up the wrapping process and make it fully automatic. The individually wrapped "fuzzy" fibers will be subsequently consolidated to form a tow of fibers. The fiber tows will be impregnated in polymer to form prepregs, which will then be stacked and fully cured to prepare composite laminates. The laminates will be characterized for thermal stability and mechanical behavior. The nanomanufacturing process as well as the material preparation configurations will be investigated through computer simulations and models. The successful completion of the project will provide a unique scalable nanomanufacturing process to provide composites with significantly enhanced interfacial shear and compressive strength without degrading fiber tensile properties.

低密度、高强度复合材料在航空航天、国防、体育、交通运输和可再生能源等广泛的技术领域发挥着关键作用。低密度材料中最重要的一类是聚合物基复合材料，其现在被用作大型客机的主要结构材料，以及其他应用，如风力涡轮机和船舶结构。在复合材料中使用纳米结构增强材料已被证明可以提高强度，从而减轻结构重量，从而节省燃料并减少生态影响。人们越来越关注和强烈需要纳米制造技术，以制造在产量和数量上可扩展的纳米结构增强材料及其复合材料。通过这个可扩展的纳米制造（SNM）奖，一个跨学科的研究团队将与工业界合作，开发一种连续的纳米制造工艺，以制造轻质，高强度的结构复合材料。纳米厚的碳纳米管织物将包裹在单个纤维上，以产生“模糊”的碳纤维，以增强其与周围聚合物的粘合强度。纳米结构复合材料将进行测试，以评估其在服务环境下的性能。使用碳纳米管织物包裹的碳纤维复合材料可以潜在地降低飞机的结构重量，提高能源效率并减少旅行时间。 该项目将为NanoExplorer计划的持续成功做出重要贡献。大量的高中生和大学生将参与这个多学科项目的各个方面。将努力招收少数民族和代表性不足群体的学生。在这个项目中，将设计、建造和组装一条连续的纳米制造线，用碳纳米管织物包裹单个纤维，而不会降低平面内碳纤维的性能。“假捻”的概念将被用来扩大包装过程，使其完全自动化。 随后将单独包裹的“绒毛”纤维固结以形成纤维丝束。纤维束将浸渍在聚合物中以形成纤维束，然后将其堆叠并完全固化以制备复合层压材料。层压材料将表征热稳定性和机械性能。纳米制造过程以及材料制备配置将通过计算机模拟和模型进行研究。该项目的成功完成将提供一种独特的可扩展纳米制造工艺，以提供具有显著增强的界面剪切和压缩强度的复合材料，而不会降低纤维拉伸性能。
