Title: The use of nonasbestos friction materials in hydrogenerators: Final report

Technical Report ·
OSTI ID:5963846

This report presents the state-of-the-art and outlook for asbestos-free friction materials for use in hydroturbine brake applications. Within the period of the study, development activities culminated in the commercial availability of several asbestos-free formulations. The emphasis in this report is a practical exposition of the requirements for friction materials in hydroturbines, the general classes of alternatives, the experience base with substitutes in the hydro industry and in other industries, a review of qualification and standards of performance for friction materials, a listing of sources for asbestos-free products, and a summary of other issues surrounding asbestos and asbestos substitutes. This report should provide guidance for specifying either original equipment or replacement brake materials. The background to alternative material types and bounding calculations of important operating parameters are also included. 49 refs., 10 figs., 12 tabs.
