SBIR Phase I: Carbon Nanofiber Reinforced Carbon Composite

这个小企业创新研究（SBIR）第一阶段项目将证明通过将催化生长和碳沉积集成到一个操作中来制造碳纳米管增强碳-碳（C-C）复合材料的可行性。该工艺的主要优点是能够以高速率在衬底上直接制造组件，从而避免了传统上使用的具有多个步骤的冗长C-C制造方法。 因此，制造复杂性、工艺周期时间和成本将大大降低。 此外，由于高密度碳和高强度碳纳米纤维以一体化的形式被设计，因此与传统的C-C复合材料相比，C-C复合材料有望具有前所未有的机械性能。 该技术的商业应用将提高C-C复合材料的可靠性，降低制造成本，从而使美国C-C复合材料产品在国际市场上更具竞争力。 这种复合材料的一个直接应用将是飞机刹车部件。该技术还可以应用于许多其他应用，如计算机硬盘介质基板和下一代医疗植入物。

This Small Business Innovation Research (SBIR) Phase I project will demonstrate the feasibility of fabricating carbon nanofiber reinforced carbon-carbon (C-C) composite by integrating catalytic nanofiber growth and carbon deposition into a single operation. The main advantage of this process is the ability to directly fabricate components on substrates at a high rate thus it avoids the conventionally used lengthy C-C fabrication approach with multiple steps. As a result, the manufacturing complexity, the process cycle time, and the cost will be greatly reduced. In addition, since high density carbon and high strength carbon nanofibers are engineered in an integrated form, the C-C composite is expected to have unprecedented mechanical properties compared with conventional C-C composite. Commercially this technology will increase the reliability and reduce manufacturing cost, thus making the American C-C composite products more competitive in the world market. One immediate application of this composite will be for aircraft brake components. The technology can also be applied to many other applications such as computer hard disc media substrates and the next generation medical implants.
