One of most critical issues is that the practical design methodology of these materials is still mainly empirical. It is not presently supported by the necessary material property database on one side and by efficient and fully adequate computational modeling and predictive analysis tools on the other. In particular, no scientific methodology is currently available for design optimization of the fiber architectures in... 

MAT.DB (Materials Property Data Base, ASM International, Metals Park, OH). Commercially updated available materials properties database developed for users interested in building their own database as well as for those who simply want access to precompiled databases. Provides flexible format for structuring diverse data types into one unified systems. Format accommodates plastics, metals, composites, wood.

A polymer material property database is provided with this text in Microsoft Excel format. At present, 48 materials are included in the database. The user can easily add materials to the database if desired. Table 6.8 gives the names and descriptions of the polymers in the files Polymer.xls. Some of the names are the common names, for example, LDPE. Others were created to be descriptive, for example, glass-reinforced epoxy as EPGR. The mechanical property names are shown in Table 6.9. 

The Madison Group and its European partner, M-Base, have developed, based on years of research and experience with material data systems, the concepts and software for the management of such application databases. This application database is searchable by part and application. Capability for general component information, multiple classifications, images and text and links to material properties is included. 

The function of the database can be further enhanced by the inclusion of links to actual material data for the component. Using such existing material database tools as MCBase, the user can quickly look-up the material properties of a component with the simple click of a button. 

Polymer and coating chemists use computer models to predict the properties of formulated products from the characteristics of the raw materials and processing conditions (1, 2). Usually, the chemist supplies the identification and amounts of the materials. The software retrieves raw material property data needed for the modelling calculations from a raw material database. However, the chemist often works with groups of materials that are used as a unit. For instance, intermediates used in multiple products or premixes are themselves formulated products, not raw materials in the sense of being purchased or basic chemical species. Also, some ingredients are often used in constant ratio. In these cases, experimentation and calculation are simplified if the chemist can refer to these sets of materials as a unit, even though the unit may not be part of the raw material database.

Rapra have published their own chemical resistance data sheets [9, 10], based on results of tests at Rapra performed by a small team of operators. They are thus comparable one with another and their sources are known. Rapra s Plascams materials selection database provides durability properties on a ranking basis and their Plastics Design Guide includes Plascams and other useful programmes. In 2002 Rapra and Faraday Plastics have launched a new website of environmental stress cracking data (www.esc-plastics.com). 

Key material properties for SOFC, such as the ionic conductivity as a function of temperature, are available in refs 36—39. In addition, Todd and Young ° compiled extensive data and presented estimation methods for the calculation of diffusion coefficients, thermal conductivities, and viscosities for both pure components and mixtures of a wide variety of gases commonly encountered in SOFCs. Another excellent source of transport properties for gases and mixtures involved in a SOFC is the CHEMKIN thermodynamic database. ... 

Question for students What is a complete set of property specifications, besides melting point and density What procedure would you use to search for the best material, which databases would you apply the procedure to, and what is the best idea that you can come up with ... 

One way to eliminate potential scale-up problems is to develop formulations that are very robust with respect to processing conditions. A comprehensive database of excipients detailing their material properties may be indispensable for this purpose. However, in practical terms, this cannot be achieved without some means of testing in production environment and, since the initial drug substance is usually available in small quantities, some form of simulation is required on a small scale.

NIST Resources. The National Institute of Standards and Technology has a Standard Reference Data Program that maintains electronic databases on Analytical chemistry, Atomic and molecular physics, Biotechnology, Chemical and crystal structure. Fluids, Materials properties. Surface data, and Thermochemical data. Some of these databases are available at moderate cost as PC products (diskettes, CD-ROMs, or Internet downloads) and some are free online systems. Further information is available on the website www. nist.gOv/srd/ begin.htm. 

Common approaches for the tailoring of nonmetallic (ceramic) materials properties involve topochemical methods (those where the crystal structure remains largely unaffected) and the preparation of phases in which one or more sublattices are alloyed. In principle, such materials are within the realm of CALPHAD. On the other hand, as has already been stated, extrapolation does not really aid the discovery of new or novel phases, with unique crystal structures. Furthermore, assessed thermochemical data for the vast majority of ceramic systems, particularly transition metal compounds, are presently not available in commercial databases for use with phase diagram software. This does not necessarily preclude the use of the CALPHAD method on these systems However, it does require the user to carry out their own thermodynamic assessments of the (n — 1 )th-order subsystems and to import that data into a database for extrapolation to nth-order systems, which is not a trivial task.
