Abstract: CMS-0600675 The objective of this research is the analysis of interfacial behavior of novel composites with fiber-matrix interfaces modified by nanoparticles. The project includes manufacturing of fibers with surfaces modified by nanoparticles, manufacturing of composites reinforced with nanomodified fibers, experimental evaluation of interfacial fracture and friction, and development of multiscale models of stress transfer, fracture, and friction in these materials. The research will provide better fundamental understanding of complex interfacial phenomena in heterogeneous materials and foster progress in methods of design and engineering of interfaces at nano- and microscales. If successful, this research can lead to improved lightweight composites with superior fracture toughness, fatigue durability, and impact resistance. Such composites will be usable in a variety of applications. The results will also be usable for other heterogeneous materials, such as polycrystalline materials and biological interfaces. Planned educational and outreach activities include support and research training of graduate and undergraduate students (the latter with support from NSF REU) and development of a new undergraduate/graduate course on nanocomposites.

摘要：CMS-0600675这项研究的目的是分析与纳米颗粒修饰的纤维矩阵界面的新型复合材料的界面行为。该项目包括制造由纳米颗粒修饰的纤维，制造具有纳米化纤维增强的复合材料，对界面裂缝和摩擦的实验评估，以及在这些材料中的压力转移，分裂和摩擦的多尺度模型的开发。这项研究将为异质材料中的复杂界面现象提供更好的基本理解，并在纳米和显微镜的界面设计和工程方法中促进进步。如果成功的话，这项研究可能会导致改进的轻质复合材料，具有出色的断裂韧性，疲劳耐用性和抗击力性。此类复合材料将在各种应用中可用。结果也将用于其他异质材料，例如多晶材料和生物界面。计划的教育和外展活动包括研究生和本科生的支持和研究培训（后者在NSF REU的支持下）以及开发纳米复合材料的新本科/研究生课程。
