Aerospace and nuclear reactor appHcations of graphite demand high reHabiHty and reproducibiHty of properties, physical integrity of product, and product uniformity. The manufacturing processes require significant additional quaHty assurance steps that result in high cost. 

FMEA was first used in the 1960s by the aerospace sector, but has since found applications in the nuclear, electronics, chemical and motor manufacturing sectors. FMEA can also apply to office processes as well as design and manufacturing processes, which are the main application areas. 

In fact, regulatory drivers are often seen as instrumental in spurring innovation. An assessment by a major aerospace manufacturer of what drives innovation towards safer processes for hazardous waste streams revealed that The regulatory drivers for waste reduction are familiar to most by now, and may be summarised into three categories of legislation 1) inventory reporting, 2) emission reporting, and 3) employee exposure levels. Anticipation of future restrictions was a decisive factor in this project. ... 

The purpose of this paper is to present a technique whereby manufacturing process dynamics for structural polymers can be accurately defined through efficient laboratory rheological characterization. Structural polymers, in this paper, refer principally to the thermosetting epoxides, phenolics and polyimides. This type of test pattern, however, is generally applicable to the production and utilization of most polymers. The engineering applications associated with these polymers involves primary and secondary aerospace articles. In this situation, failure to meet performance criteria could result in catastrophic loss of the vehicle and associated cargo. 

Silver-White metal or dusts. Reacts with some acids to produce flammable hydrogen gas. Exposures have occurred in nuclear and aerospace workers may be present in any specialty metal alloy manufacturing process.
