0099629Singh This study will investigate the toughening of highly cross-linked thermosetting polymers by the incorporation of various nanoparticles. A direct fabrication technique will be used to independently control the reinforcement geometry (size, size distribution and morphology), reinforcement material, reinforcement volume fraction, and interfacial adhesion characteristics. The effects of these reinforcement parameters, on the fracture mechanisms, fracture toughness and material response, will be characterized by direct experimentation. Based on this fundamental characterization analytical/numerical models will be developed to predict the overall material response and toughness. The education component of this investigation is targeted towards increased integration between undergraduate education and research with special emphasis on increasing the participation of underrepresented minorities in engineering. Undergraduate students will be recruited to work on various tasks relevant to the research component. At the same time, specific research findings and projects will be introduced into undergraduate courses that focus on the behavior of materials. Also, students will make periodic visits to local high schools and setup in-house laboratory demonstrations. These activities will expose high school students to the excitement and challenges of innovative materials based on cutting-edge nanotechnology. Finally, results from the education and research activities will be published regularly on a dedicated web page, which will enable concurrent feedback and interaction unlike traditional paper-based publication.***

本研究将通过加入不同的纳米颗粒来研究高交联型热固性聚合物的增韧。一种直接制造技术将用于独立控制增强体几何形状(尺寸、尺寸分布和形态)、增强体材料、增强体体积分数和界面粘结特性。这些加固参数对断裂机制、断裂韧性和材料响应的影响将通过直接实验来表征。基于这一基本特性，将开发分析/数值模型来预测整体材料的响应和韧性。这项调查的教育部分旨在加强本科教育和研究之间的融合，特别强调增加未被充分代表的少数群体参与工程学。本科生将被招募来从事与研究部分相关的各种任务。同时，将具体的研究成果和项目引入到专注于材料行为的本科课程中。此外，学生们还将定期访问当地的高中，并建立内部实验室演示。这些活动将使高中生接触到基于尖端纳米技术的创新材料的兴奋和挑战。最后，教育和研究活动的结果将定期发布在专门的网页上，这将与传统的纸质出版物不同，实现同步反馈和互动。*
