This proposal requests funds to permit Dr. Danny D. Edie, Co-Director, Advanced Engineering Fibers Laboratory, Clemson University, to pursue with Dr. Bosung Rhee, Professor of Chemical Engineering, Chungnam National University, Taejon, Korea, and Dr. Erich Fitzer, Director, Institute for Chemical Technology, Universitat Karlsruhe, Federal Republic of Germany, for a period of 24 months, a program of cooperative research on hollow and c-shape carbon fiber from pitch and its applicability to carbon fiber reinforced composite (CFRC) materials. In this research, a commercial mesophase precursor will be extruded into non-circular fibers which have a higher strength and strain-to-failure ratio than present round commercial carbon fibers. Initial studies show that the properties of these non-circular fibers depend on the fiber shape, the extrusion velocity, the fiber size, and the composition of the mesophase. In this research project, mesophase precursors will be produced at Chungnam National University and Universitat Karlsruhe. The chemical nature and the molecular weight distribution of the mesophase materials will be analyzed at Clemson University as well as by the Korean and German research groups. Equipment available at the Korea Research Institute for Chemical Technology, near Chungnam University, will be used to measure the functional groups and aromatic character of the mesophase samples, while rheology analyses will be carried out at Clemson University. Composite structures of carbon fibers and plastic are being increasingly utilized in aircraft and automotive applications because their strength-to-weight ratio is greater than the best metal alloys available. Many aircraft wing structures are currently fabricated with carbon/epoxy composite material, while automobile manufacturers are presently testing composites of carbon fibers and plastics for use in leaf and coil springs, drive shafts, body frames and body side panels. Successful completion of this project could offer industry superior reinforcing fibers manufactured from a low cost raw material. This is a unique project which will bring the research strengths/expertise of U.S., Korean, and German institutions/scientists to bear on a problem of mutual interest and potential benefit. The PI's are highly respected scientists who have collaborated successfully in the past. This project is relevant to the objectives of the U.S.-Republic of Korea and U.S.-Federal Republic of Germany Cooperative Science Programs which seek to increase the level of cooperation between scientists and engineers of these countries through the exchange of scientific information, ideas, skills, and techniques and through collaboration on problems of mutual benefit. This project will add an international cooperative dimension to Dr. Edie's research under NSF Grant No. ENG-8710385.

该提案要求资金允许克莱姆森大学高级工程纤维实验室联合主任丹尼·D·埃迪（Danny D. C形碳纤维从俯仰及其适用于碳纤维增强复合材料（CFRC）材料。 在这项研究中，商业中间体前体将被挤出到非圆纤维中，其强度和应变比比目前的商业碳纤维更高。 初步研究表明，这些非圆纤维的特性取决于纤维的形状，挤出速度，纤维尺寸和中间体的组成。 在该研究项目中，将在Chungnam国立大学和Karlsruhe大学生产中间体前体。 将在克莱姆森大学以及韩国和德国的研究小组中分析中间体材料的化学性质和分子量分布。 Chungnam University附近的韩国化学技术研究所可用的设备将用于测量中间体样品的功能组和芳香特征，而流变学分析将在Clemson University进行。 碳纤维和塑料的复合结构越来越多地用于飞机和汽车应用中，因为它们的强度重量比大于可用的最佳金属合金。 目前，许多飞机机翼结构都用碳/环氧复合材料制造，而汽车制造商目前正在测试碳纤维和塑料的复合材料，用于叶子和线圈弹簧，驱动轴，车身框架和车身侧面板。 该项目的成功完成可以为行业提供优质的增强纤维，从而通过低成本原材料制造。 这是一个独特的项目，它将带来美国，韩国和德国机构/科学家的研究优势/专业知识，以解决共同利益和潜在利益的问题。 PI是过去成功合作的备受尊敬的科学家。 该项目与韩国和美国 - 联邦共和国的美国共和国合作科学计划的目标相关，该计划试图通过交流科学信息，思想，技能和技术以及通过在相互利益问题上的协作来提高这些国家科学家与工程师之间的合作水平。 该项目将为Edie博士的研究增添国际合作维度。
