Title: Between dreams and reality of metal-matrix composites -- a big gap?

Abstract

The potential benefits and the current state-of-the-art in MMCs will be presented through a discussion of their processing and related aspects. The advantages and limitations of most common manufacturing techniques of fiber reinforced metals, e.g. realized property potential and commercial possibilities, will be outlined. The emphasis will be given on novel powder metallurgy techniques such as rapid solidification (e.g. atomization techniques and plasma processes) and new materials systems (e.g. intermetallic matrix composites). The technical barriers which prevent the transition of MMCs from aerospace to a wider range of applications will be highlighted, Special attention will be drawn to the relation between processing parameters, fiber-matrix interface and composite properties. The challenge of composite modeling and design as well as interface controlling for successful processing utilization of MMCs will be mentioned. The benefits of use of computer techniques (databases, simulations, knowledge based systems) to aid the composite design and process control (fuzzy logic) will be shown on several examples. The technical possibilities of adaptation of interface tailoring approaches from the PMC area such as graded interphase or rubber-bumper interface will be studied. In addition, on the basis of recent forecasts by different experts on composite materials the question of the MMCs futuremore » will be discussed. Have they a chance in the next few years to meet the requirements of successful commercial applications, especially those of clients? The problems which have to be solved and options for solution will be dealt with.« less
