Nanofiber Reinforcement for Medical Implants

描述(由申请人提供)： 医疗植入物用纳米纤维增强材料项目概述拟议的SBIR第一阶段项目是通过将催化纳米纤维生长和碳沉积集成到单一操作中来优化生产用于医疗植入物的碳纳米纤维增强碳-热解碳(C-PYC)复合材料的工艺。这一工艺的主要优点是能够将高强度碳纳米纤维结合到经过验证的生物相容性热解碳涂层中，以创建一种新的生物材料。此外，由于高生物相容性的热解碳和高强度碳纳米纤维是以一体化的形式设计的，与传统的热解碳涂层相比，C-PYC复合材料有望具有更好的力学性能。总体而言，这项技术将提高产品的可靠性，降低制造成本，从而使美国产品在世界市场上更具竞争力。这种复合材料的一个直接应用将是下一代医疗植入物。由于这项技术直接在基板上高速制造部件，它还可以应用于许多其他应用，如计算机硬盘介质基板和航空航天部件。 关键词：生物材料、医用植入物、热解碳涂层、纳米纤维复合材料

DESCRIPTION (provided by applicant): Nanofiber Reinforcement for Medical Implants Project Summary The proposed SBIR Phase I project is to optimize a process of producing carbon nanofiber reinforced carbon-pyrolytic carbon (C-PyC) composite for medical implants by integrating catalytic nanofiber growth and carbon deposition into a single operation. The main advantage of this process is the ability to incorporate high strength carbon nanofibers into proven biocompatible pyrolytic carbon coating to create a new class of biomaterial. In addition, since highly biocompatible pyrolytic carbon and high strength carbon nanofibers are engineered in an integrated form, the C-PyC composite is expected to have improved mechanical properties compared with conventional pyrolytic carbon coating. Overall this technology will increase the product reliability and reduce manufacturing cost, thus making the US products more competitive in the world market. One immediate application of this composite will be the next generation medical implants. Since this technology directly fabricates components on substrates at a high rate, it can also be applied to many other applications such as computer hard disc media substrates and aerospace components. Key words: Biomaterial, medical implants, pyrolytic carbon coating, and nanofiber composite
