This Small Business Technology Transfer (STTR) Phase I project will develop methods for generating alignment of short but highly graphitic and inexpensive nanofibers in polymer matrix composites. These efforts, carried out by Applied Sciences, in collaboration with its subcontractor, Ohio University, are expected to result in excellent mechanical reinforcement of the matrix, and effectively achieve the elusive goal of simultaneously attaining high modulus, high strength, and low cost from a carbon fiber reinforcement. Carbon nanofibers will be made to align in thin, extruded strands of thermoplastic polymer that can then be laid up and molded into composites by conventional textile handling techniques. The formation and lamination of papers from the short fibers will also be explored. Composites will be tested for mechanical properties and evaluated for the degree of fiber alignment actually obtained.A wide variety of military and commercial applications would benefit from carbon fiber reinforced composites. Any application that currently uses chopped glass fiber reinforcement could be replaced by a carbon fiber reinforced component with improved mechanical properties. Application that can benefit from added electrical conductivity in composites panels, such as low observable materials for aircraft, EMI control enclosures, and automotive panels that need electrostatic painting techniques.

这个小企业技术转让（STTR）第一阶段项目将开发用于在聚合物基复合材料中产生短但高度石墨化和廉价的纳米纤维的方法。 这些努力由Applied Sciences与其分包商俄亥俄州大学合作进行，预计将导致基质的优异机械增强，并有效地实现从碳纤维增强材料同时获得高模量、高强度和低成本的难以捉摸的目标。 碳纳米纤维将排列成薄的热塑性聚合物挤出线，然后可以通过传统的纺织品处理技术铺叠并模塑成复合材料。 还将探讨短纤维纸张的形成和层压。 复合材料将被测试的机械性能和评估的程度纤维排列实际获得。各种各样的军事和商业应用将受益于碳纤维增强复合材料。 目前使用短切玻璃纤维增强的任何应用都可以被具有改进的机械性能的碳纤维增强部件所取代。 可受益于复合材料面板中增加的导电性的应用，例如用于飞机的低可见性材料、EMI控制外壳和需要静电喷涂技术的汽车面板。
