This Small Business Innovation Research Phase I project will investigate the effectiveness of forming novel carbon nanofibers by a gas jet process (NGJ) and confirm performance benefits as these nanofibers are incorporated into polymer systems. Carbon fibers of various diameters enhance a broad range of materials and products to increase the strength-to-weight ratio and improve thermal and electrical properties of composite structures. However, a substantial gap in available fiber diameters exists between the largest nanofiber (100 nm) and the smallest microfiber (3000 nm). A similar gap exists in the aspect ratio of the fibers. Laboratory demonstrations have shown the NGJ process produces fibers that fill these gaps. The objectives of this project are to develop the equipment and procedures that demonstrate the high volume and low cost advantages of NGJ nanofibers reproducibly in important applications. This project consists of 1) design and fabrication of pilot scale equipment, 2) production and characterization of nanofibers, 3) preparation of composite samples, and 4) comparison of composites reinforced with NJG nanofibers to those reinforced with commercially available nanofibers. The results of this research will prove the advantages of the NGJ nanofibers and their commercial viability. Completion of this project will provide an understanding of the impact of larger diameter, higher aspect ratio carbon nanofibers on composite polymer performance. Additionally, the design and optimization of composite components and the process controls of fabrication will be improved by the availability of a wide range of diameters of the graphitic reinforcing nanofibers fibers. Also, fundamental morphological differences will be revealed in the way that graphene-like sheets are arranged in fibers of varying diameters produced by the NGJ process. This project will lead to the commercialization of low cost, high performance carbon nanofibers with unique mechanical properties. Benefits to society from these materials will include lighter weight, higher strength components utilized in most automobiles, which will reduce fuel consumption. Also, when used as affordable high performance fillers in lithium ion battery electrodes, these carbon nanofibers will help electric cars achieve mass appeal. Additional benefits will arise from the significant performance improvements and cost reductions that occur as the low cost, high performance materials are incorporated into manufacturing processes, packaging products, adhesives, and many other supply chain materials.This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5).

该小型企业创新研究第一阶段项目将研究通过气体喷射工艺 (NGJ) 形成新型碳纳米纤维的有效性，并确认将这些纳米纤维纳入聚合物系统时的性能优势。 各种直径的碳纤维可增强各种材料和产品，以提高复合材料结构的强度重量比并改善热性能和电性能。 然而，最大的纳米纤维（100 nm）和最小的微纤维（3000 nm）之间的可用纤维直径存在很大差距。 纤维的长径比也存在类似的差距。 实验室演示表明 NGJ 工艺生产的纤维可以填补这些空白。 该项目的目标是开发设备和程序，在重要应用中可重复地展示 NGJ 纳米纤维的高产量和低成本优势。 该项目包括 1) 中试规模设备的设计和制造，2) 纳米纤维的生产和表征，3) 复合材料样品的制备，以及 4) 用 NJG 纳米纤维增强的复合材料与用市售纳米纤维增强的复合材料的比较。 这项研究的结果将证明 NGJ 纳米纤维的优势及其商业可行性。 该项目的完成将有助于了解更大直径、更高长径比的碳纳米纤维对复合聚合物性能的影响。此外，复合材料部件的设计和优化以及制造过程控制将通过提供各种直径的石墨增强纳米纤维而得到改善。 此外，通过 NGJ 工艺生产的不同直径的纤维中类石墨烯片的排列方式也将揭示基本的形态差异。 该项目将导致具有独特机械性能的低成本、高性能碳纳米纤维的商业化。 这些材料给社会带来的好处包括大多数汽车中使用的部件重量更轻、强度更高，从而减少燃料消耗。 此外，当这些碳纳米纤维用作锂离子电池电极中经济实惠的高性能填料时，将有助于电动汽车获得大众的青睐。 当低成本、高性能材料被纳入制造工艺、包装产品、粘合剂和许多其他供应链材料时，显着的性能改进和成本降低将带来额外的好处。该奖项由美国复苏和再投资项目资助2009 年法案（公法 111-5）。
