U.S.-Austria Cooperative Research: Synthesis of High Performance Ceramic Fibers by Chemical Vapor Deposition for Advanced Metallics Reinforcing.

该奖项支持纽约州立大学布法罗分校（SUNY/B）反应与陶瓷工程实验室的Vladimir Hlavacek博士与维也纳技术大学无机材料技术研究所的B.F. Lux博士在金属基复合材料方面的合作研究。这两个实验室合作的最终目标是开发一种化学气相沉积（CVD）工艺，用于制造具有良好机械性能和高热膨胀系数值的陶瓷纤维。SUNY/B小组目前的工作是在碳芯上对二硼化钛、碳化钛或碳化硼进行气相沉积，这是制造具有这种性能的无机纤维的有前途的途径之一。他们现在有兴趣将这项工作扩展到包括铍化合物。需要进行基础工程研究，以开发高度控制的加工操作和条件，从而在长长度和最小涂层缺陷的情况下生产始终如一的高纤维强度。SUNY/B在CVD方面有丰富的经验，拥有优良的设备和使用各种芯材合成不同直径的连续单丝的经验。而奥地利研究所在CVD工艺和包括铍化物在内的陶瓷材料方面拥有不同寻常的专业知识。航空航天系统和其他类别的车辆和机械不断提高的性能要求要求材料具有低重量，高强度，高刚度和高温能力。金属基复合材料似乎具有这些特性，但生产这种先进材料需要大量的基本信息，包括控制延展性和强度的因素、环境影响以及复合材料中纤维和基体之间的相互作用。拟议的合作提供了跨学科的互补技能和知识组合，这是在这一具有重要战略意义的领域取得进展所需要的。

This award supports Dr. Vladimir Hlavacek of the Laboratory for Reaction and Ceramic Engineering of the State University of New York at Buffalo (SUNY/B) in a research collaboration on metal matrix composites with Dr. B.F. Lux of the Institute for Inorganic Materials Technology of the Technical University of Vienna. The ultimate goal of the collaboration between these two laboratories is to develop a chemical vapor deposition (CVD) process for manufacturing of ceramic fibers with good mechanical properties and high values of thermal expansion coefficients. Current work by the SUNY/B group on CVD of titanium diboride, titanium carbide or boron carbide on a carbon core is one of the promising routes to manufacture an inorganic fiber with such properties. They are now interested in extending this work to include beryllium compounds. Basic engineering research is needed to develop highly controlled processing operations and conditions that will produce consistently high fiber strengths over long length and with minimal coating defects. SUNY/B has experience with CVD and excellent facilities and experience working with various core materials to synthesize continuous monofilaments of different diameters, while the Austrian Institute has unusual expertise in CVD processes and in working with ceramic materials including the beryllides. The ever increasing performance requirements of aerospace systems and other classes of vehicles and machinery call for materials with low weight, high strength, high stiffness and high temperature capabilities. Metal matrix composites appear to offer these characteristics, but production of such advanced materials requires substantial basic information about factors that control ductility and strength, environmental effects, and interactions between fiber and matrix in composites. The proposed collaboration offers the interdisciplinary mix of complementary skills and knowledge that is needed to make progress in this strategically important field.
