U.S.-India Cooperative Research: Studies on Fibre-Matrix Bonding and Physical Properties of Carbon-Carbon Composites Made with Carbon Fibres of Different Morphologies

这是一个材料科学领域的研究项目，名为“美印合作研究：用不同形态的碳纤维制成的碳-碳复合材料的纤维基体粘合和物理特性研究”。该项目为国内研究增加了国际成分，由克莱姆森大学的丹尼·伊迪和萨达尔帕特尔大学的L.M.马诺查指导。这项研究的目标是开发一种低成本的高性能碳纤维材料。由美国国家科学基金会资助的克莱姆森大学正在进行的一项研究表明，通过生产非圆形纤维，可以大大提高低成本沥青基碳纤维的机械性能和热性能。这些非圆形纤维的最终性能受到挤压过程中的流动条件和中间相前驱体的分子组成的影响。与Manocha教授组的合作，将对这些非圆形纤维在碳/聚合物和碳/碳复合材料中进行测试和评价。这项在克莱姆森进行的额外测试将确定增强的纤维性能是否转化为改进的复合材料性能。范围：此次合作通过包括印度在碳/碳复合材料制造和表征方面的专业知识，为国内研究增加了一个重要的维度。印度同行在这一领域领导着一个强大的研究计划，并因其在这类高温材料方面的工作而得到国际认可。美国研究人员的专长是纤维的形成和特征。该项目为两所大学的研究生提供了一个通过参与国际团队获得独特研究视角的机会。这种共同努力在技术上是平衡的，应该会带来互利。＊＊＊

9616298 Manocha Description: This is a research project in materials science entitled U.S.-India Cooperative Research: Studies of Fiber Matrix Bonding and Physical Properties of Carbon-Carbon Composites Made with Carbon Fibers of Different Morphologies. The project which adds an international component to domestic research is under the direction of Danny Edie of Clemson University and L.M. Manocha of Sardar Patel University. The goal of the research is to develop a low-cost carbon fiber for high- performance materials. The ongoing NSF supported research at Clemson has shown that mechanical and thermal properties of low-cost pitch-based carbon fibers can be greatly improved by producing non-circular fibers. The ultimate properties of these non-circular fibers are influenced by flow conditions during extrusion and the molecular make-up of the mesophase precursor. The collaboration with Professor Manocha s group will permit testing and evaluation of these non-circular fibers in carbon/polymer and carbon/carbon composites. This addition to the testing at Clemson will determine if the enhanced fiber properties translate into improved composite performance. Scope: This collaboration adds an important dimension to domestic research through the inclusion of complimentary Indian expertise in fabrication and characterization of carbon/carbon composites. The Indian counterpart heads a strong research program in this area and is recognized internationally for his work with this class of high- temperature materials. The U.S. investigator s expertise is in fiber formation and characterization. The project provides an opportunity for graduate students at both universities to gain a unique research perspective through participation in an international team. This joint effort is well balanced technically and should result in mutual benefits. ***
