Typical applications and current materials usage are summarized in the following table. However, many of the available highly fire-resistant materials find limited application in aircraft interiors because of the requirements for aircraft interiors such as weight, cost, manufacturability, and end-use suitability.

For marry commercial applications, such as buildings, the fire resistance requirements are not very stringent, so the materials used have less fire resistance than those used in aircraft applications. In specially high-cost and vulnerable items such as manned space vehicles and submarine applications where fire is an extreme hazard, materials that are more fire resistant are used.

State of the Materials and Fabrication Industries Although there is still adequate research capability within the materials and fabrication industries, there has been a substantial curtailment of research capability over the past few years with the downsizing of aerospace materials research. This is in part due to a downturn in the defense industry activities and in part due to a downturn in the commercial aviation business.

Also, the potential of anticipated future regulation would cause material manufacturers to consider working on new materials in anticipation of a potential future profit. Differences in regulations among worldwide regulatory agencies tend to drive the implementation of materials and structures that are compliant with the most stringent requirements, since the use of multiple materials for a common application is costly.

The high cost of qualification and certification of a new material for aircraft applications makes embarking on a material development and implementation program risky for both the materials supplier and the aircraft manufacturer. Downsized industry research organizations will have more difficulty performing the work necessary to develop and commercialize new materials.
