The Small Business Innovation Research (SBIR) Phase I project will develop and characterize a novel class of polymer matrix composite materials using the continuous NanoFiber Fused- Microfiber (Nf2-M) reinforcement technology developed by the company. In this patent pending process, carbon nanofibers are grown in a continuous process directly from the surface of continuous filaments (introduced in tow form) in a continuous, scaleable process. Unlike traditional approaches which involve difficult mixing operations to introduce carbon nanofibers into the matrix resin at very low loading levels and with questionable dispersion, the above approach produces continuous three-dimensional reinforcements which are easily incorporated into composites using standard fabrication techniques, including filament winding and prepreg wet lay-up processes. No additional or modified composite fabrication steps are needed. For initial demonstration of the advanced composite microstructure methodology, Nf2-M reinforcing fibers will be used to fabricate aerospace grade epoxy composites and physical, mechanical, electrical, and thermal properties will be measured.The scientific, economic, and societal impacts of the proposed research are threefold: (i) providing a foundation for a new technology in materials science research; (ii) utilizing these fundamental findings to develop and engineer enabling materials to meet growing needs in industry for current and future applications; and (iii) providing a low cost, commercially available, high performance carbon fiber reinforcement technology that has the potential to change the face of the composite materials industry. Global market forecast for reinforcing carbon fibers is ~$12.2 billion annually by 2011, and the novel approach proposed in this research can take advantage of the multitude of existing markets. Sporting goods, electronics, consumer products, aerospace, and automotive industries are all target markets of the proposed materials technology.

小企业创新研究（SBIR）第一阶段项目将使用该公司开发的连续纳米纤维熔融-微纤维（Nf 2-M）增强技术开发和表征一类新型聚合物基复合材料。在该专利申请中的方法中，碳纳米纤维在连续的、可缩放的方法中直接从连续长丝（以丝束形式引入）的表面在连续的方法中生长。与涉及困难的混合操作以在非常低的负载水平和可疑的分散下将碳纳米纤维引入基质树脂中的传统方法不同，上述方法产生连续的三维增强材料，其易于使用标准制造技术（包括长丝缠绕和预浸料湿铺层工艺）并入复合材料中。不需要额外的或修改的复合材料制造步骤。作为先进复合材料微观结构方法的初步示范，Nf 2-M增强纤维将用于制造航空航天级环氧复合材料，并将测量其物理、机械、电气和热性能。拟议研究的科学、经济和社会影响有三个方面：（i）为材料科学研究的新技术提供基础;（ii）利用这些基本发现来开发和设计使能材料，以满足当前和未来应用的工业中日益增长的需求;以及（iii）提供低成本、可商购的、高性能的碳纤维增强技术，其具有改变复合材料工业面貌的潜力。到2011年，全球增强碳纤维市场预测每年约为122亿美元，本研究提出的新方法可以利用现有的众多市场。体育用品、电子产品、消费品、航空航天和汽车行业都是拟议材料技术的目标市场。
