U.S.-France Cooperative Research: Microstructure Development and Creep Behavior of Polymer Derived Silicon Carbide Fibers and CVI Microcomposites

这个为期两年的奖项支持宾夕法尼亚州立大学的Richard E. Tressler和波尔多大学的Roger Naslain在材料科学方面的美法合作研究。该研究的目标是利用聚合物加工技术开发优异的高温纤维（碳化硅基复合材料），并将这些纤维的化学成分/热稳定性与微观结构和蠕变性能联系起来。美国研究人员为此次合作带来了微观结构和蠕变特性方面的专业知识。最近法国在纤维加工方面的工作补充了这一点。碳化硅基复合材料是航空航天和工业过程机械应用的主要候选材料。然而，目前的候选材料在尺寸和热阻方面受到限制。该项目将促进对其结构和性能的理解，并导致目前无法获得的高温纤维的开发。＊＊＊

9314784 Tressler This two-year award supports U.S.-France cooperative research in materials science between Richard E. Tressler of Pennsylvania State University and Roger Naslain of the University of Bordeaux. The objectives of the research are to develop superior high-temperature fibers (silicon carbide matrix composites) using polymer processing and to relate the chemical composition/thermal stability to microstructure and creep properties of these fibers. The U.S. investigator brings to this collaboration expertise in microstructure and creep properties. This complemented by recent French work in fiber processing. Silicon carbide matrix composites are leading candidates for aerospace and industrial process machinery applications. However, current candidates are limited in size and in thermal resistance. This project will advance understanding of their structure and properties and lead to the development of high temperature fibers that are not currently available. ***
