The broader impact of this SBIR Phase I project will be materials that are lighter weight, tougher and more durable than existing carbon fiber reinforced polymer composites. This will allow companies incorporating these materials into their products to save energy by making products and vehicles that are lighter weight and also to improve range and fuel economy which will subsequently reduce greenhouse gas emissions. In aerospace applications payloads will be reduced saving both money and energy. In defense applications, tougher materials will improve reliability and reduce field repairs, which can be dangerous. In all these applications, the likelihood of catastrophic failures is reduced. This Small Business Innovation Research Phase I project will enhance the strength of carbon fiber reinforced polymer composites (CFRPs) by improving the fiber/matrix integration and developing an interlayer (sizing layer) to protect CFRPs from being broken down by stress accumulated at the interface. This project will minimize or eliminate the interfacial weak points by using a patented surface engineering process. The process functionalizes the surface of the carbon fibers and dramatically promotes the wettability of the matrix resin on the fiber surface. The principal technical objective is to develop a surface engineering process that will improve the fiber/matrix wettability. Distinguished from the reported methods, the proposed surface engineering will process fibers larger than 100 mm in any dimension and more than five plies per load. Carbon nanotubes (CNTs) will be added to the sizing polymer to facilitate stress transfer between the carbon fiber reinforcements and the matrix.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

该SBIR I期项目的更广泛的影响是比现有的碳纤维增强聚合物复合材料更轻，更坚固，更耐用的材料。这将允许将这些材料纳入其产品中，以通过制造重量减轻并改善范围和燃油经济性的产品来节省能源，从而减少温室气体的排放。在航空航天申请中，有效载荷将减少节省金钱和能源。在国防应用中，更坚固的材料将提高可靠性并减少现场维修，这可能是危险的。在所有这些应用中，灾难性失败的可能性降低了。这个小型企业创新研究阶段I项目将通过改善纤维/基质集成并开发层间（尺寸层）来保护CFRP，以保护CFRP，以保护CFRP，以保护CFRP，从而增强了碳纤维增强聚合物复合材料（CFRP）的强度。该项目将使用专利的表面工程过程最大程度地减少或消除界面弱点。该过程功能化碳纤维的表面，并大大促进了纤维表面上基质树脂的润湿性。主要技术目标是开发一个可以改善纤维/矩阵润湿性的表面工程过程。与报道的方法区分开，所提出的表面工程将在任何维度上处理大于100 mm的纤维，每个负载五个以上的平原。碳纳米管（CNT）将添加到尺寸聚合物中，以促进碳纤维增援和矩阵之间的压力转移。该奖项反映了NSF的法定任务，并被认为是值得通过基金会的知识分子优点和更广泛影响的审查标准来通过评估来获得支持的。
