2013年5月30日-6月2日，德国凯泽斯劳滕工业大学 (Technical University of Kaiserslautern) Klaus Friedrich教授来访，并为我系师生做了题为“Multi-Functionality in Reinforced Polymers and Composite Structures”的学术报告。 报告摘要： Multi-functionality is the combination of different properties in one material so as to make it suitable for the use in applications in which different loading conditions must be sustained. Besides the mechanical load bearing capacity, other properties such as thermal stability, electrical conductivity or wear resistance can be of importance. In many cases, polymer based composites are the material of choice, since they can combine the intrinsic properties of the polymers (like light weight, corrosion resistance or toughness) with the unique properties of their reinforcements (such as electrical conductivity, wear resistance, or high mechanical stiffness and strength.) The present contribution illustrates how multi-functionality can be achieved in reinforced polymers and composite structures, using different types of polymer matrices and various nano-sized and micro-sized fillers, reinforcements or coatings. Besides the principle concepts, various case studies are represented, illustrating different processing routes how to achieve various property combinations for different specific applications. The latter include high temperature thermoplastic based composites for sliding wear loaded components, carbon nanotube/short fiber reinforced thermoplastics used for electrically conductive parts, film coated composites structures, in which high stiffness and strength together with high surface erosion resistance are required (e.g. wind energy rotor blades), and high temperature thermosetting coatings for reducing sliding friction and wear of automotive engine pistons, etc. Prof. Klaus Friedrich个人简历： Prof. Friedrich earned his PhD degree at Ruhr-University Bochum in Germany in 1978. He became Research Director for Materials Science at the Institute for Composite Materials (IVW), University of Kaiserslautern, Germany in 1990. He has published more than 800 papers and is listed as a highly cited researcher in material science (with an H-index of 54). In 2005, Prof. Friedrich was honored as a World Fellow of the International Committee on Composite Materials (ICCM). He now acts as a research consultant for various institutes and industrial companies and is a part-time professor at the King Saud University.
