Abstract
A carbon-carbon composite friction disc is formed from two or more carbon-based structural components secured together by an interface layer which is not itself a structural member but is fusion-bonded to both of the structural components to secure them together. The interface layer may be of metallic material such as a brazing compound, or may be of non-metallic material such as pitch.
