Aging technology

Although there is a lot of science and space-age technology involved in the construction of composites, many composites have been initially formulated through a combination of this science and trial-and-error, giving recipes that contain the nature and form of the fiber and matrix materials, amounts, additives, and processing conditions.

The Mitteldeutsche Erdoel Rafenerie Middle German Petroleum Refinery (MIDER) was built and operated by Elf in 1995. This refinery is especially interesting, because of the application of cutting age technologies and processes in the refinery. Some details concerning this refinery are given below.

The multitudinous needs of our space-age technology are among the driving forces for the development of a host of new materials with remarkable properties. Thermally stable or high-temperature pol5uners have received a major share of the attention of workers engaged in the synthesis and study of these products. 

Technological History. Archaeologists often divide the neolithic period, the latter part of what used to be called the Stone Age, into pre- and post ceramic, with reference to when ceramics came into production (88—92). Actually, there are occasions of pre-ceramic pyrotechnology, such as in the case of the fifth millenium BC mideastem plaster production (93). So far the eadiest occurrence of ceramics is in the 28th millenium BC in Eastern Europe, although here the technique was not used for the production of vessels but of figurines (94). 

Through its committees, divisions, and chapters, the American Vacuum Society has produced a nearly complete bibhography (to 1996) (8), a dictionary of terms (9), a monograph series, and a number of other useful pubHcations (10). Another source of information is the Association of Vacuum Equipment Manufacturers. A history of vacuum ideas and technology development from the Middle Ages to Newton has been given (11). 

Asphalt (bitumen) also occurs in various oil sand (also called tar sand) deposits which occur widely scattered through the world (17) and the bitumen is available by means of various extraction technologies. A review of the properties and character of the bitumen (18) suggests that, when used as an asphaltic binder, the bitumen compares favorably with specification-grade petroleum asphalts and may have superior aging characteristics and produce more water-resistant paving mixtures than the typical petroleum asphalts.
