‘Smart’ technologies, which encompass both ‘smart’ materials and structures, are creating a sea-change in engineering practice. Their fusion of conventional structural materials with aspects of information technology, offerss the prospect of engineering systems which can sense their local environment, interpret changes in this environment and respond appropriately. Demonstrator projects exist world-wide exploring the range of possible applications for ‘smart’ technologies in sectors ranging from aerospace and civil engineering to automobile and marine. A common feature of such programmes is their use of relatively sophisticated technologies, examples including the use of fibre optic techniques for sensing and actuation based on functional materials such as piezoceramics, electro- and magnetostrictives and shape-memory alloys. The use of such advanced technologies is symptomatic of the strong technology push which has dominated the development of this field. 相似文献

AbstractThere is a growing need in both aerospace and commercial markets for lighter weight, higher stiffness, higher thermal stability materials to solve the design engineers’ problems of reduced mass, higher access speeds, improved mechanical and thermal stability for today's advanced technology. To address those needs, Brush Wellman Inc. has developed, characterised, and put into high volume production a family of beryllium metal matrix composites. There are two classes of materials that have been developed to provide these engineering benefits to the designer in both the commercial and aerospace markets. The first family of materials is aluminium beryllium (AlBeMet, which is a registered tradename of Brush Wellman). This material is a metal matrix composite consisting of pure beryllium and aluminium, with 20–62 vol.-%Be and the remainder aluminium. The material is produced by both powder metallurgy and net shape technologies such as investment casting and semi-solid forming. The materials properties that make it attractive for the design engineer are a density that is 25% less than that of aluminium, a specific stiffness four times those of aluminium, titanium, steel, and magnesium, a higher dampening capacity than aluminium, and a coefficient of thermal expansion almost 50%lower than aluminium. The second family of materials is a beryllium–beryllium oxide metal matrix composite, which are called E materials. This material was developed to address the thermal management needs of the electronic packaging design engineer. The material properties that make this material attractive to the electronic packaging engineer are: a density 20–25% that of Kovar, Invar, and CuMoCu, and 30% less than Al–SiC; a thermal conductivity ranging from 210 to 240 W m-1 K-1and a tailorable coefficient of thermal expansion, ranging from 6×10-6 to 8.7×10-6 K-1. 相似文献

The changing demands of the consumer over the last 50 years are reviewed. The resultant changes in packaging required to meet these demands are considered, particularly for fast‐food outlets, ‘smart shopping’ where food is ordered and delivered direct to the home and other types of electronic shopping. The changes needed in packaging materials and processes and in transport packaging are assessed. Copyright © 1999 John Wiley & Sons, Ltd. 相似文献

To make packaging truly beneficial to human beings, it is important to help people learn more about the great variety of packaging materials and packaging techniques. In applying that knowledge, certain ethics should be observed by those engaged in packaging activities. The first step in achieving this task is to recognize what constitutes the packaging sciences, and from the results of various investigations a system of packaging sciences has been produced. Packaging science, as we have organized it, consists of the three major fields of packaging sociology, packaging materials science and packaging technology. With regard to the ethics that should form the backbone for the varied packaging activities, we propose that a Packaging Charter be established, incorporating the basic spirit and the ideas outlined herein. 相似文献

That’s what the market research fraternity seem to think. Talking to the analysts, those financial heavyweights with the power to urge ‘buy’ or ‘sell’, Frost & Sullivan’s Joseph Constance discussed the newest first part of a Frost & Sullivan two part report on Smart Materials, but never let a figure slip.As disappointing as the 3i survey on nanotechnology, this report considers that smart materials are, still, after decades, only a ‘frontier’ technology. Expect plenty of interesting applications, lots of research, but no hard figures.In other reports on Smart Materials from BCC, market figures give way to a technology assessment, (a patent review, and a look at market potential) and finally a report that focus on niche smart areas – sol gel. But, frontier or emerging, everyone is still shy of smart market numbers, year on year. 相似文献

Understanding how easy packaging is to open is becoming a major area of interest for the packaging industry. Designing packaging to meet the direct needs of the consumer has been termed ‘inclusive design’. However, there are differing parameters that may affect the ease of opening a product. This paper outlines how the use of uncertainty analysis coupled with ‘inclusive design’ techniques can help manufacturers understand which parameters are important for product ‘openability’.
