GRUPPI COMPOSITI DI FRIZIONE E PROCEDIMENTI PER FABBRICARLI

摘要

The present invention relates to composite friction assemblies and to methods of making the assemblies. The assemblies include at least one friction member and a support member. The friction member is formed from a mixture of thermosettable phenol-aldehyde resin and filler material under conditions less than those which would thermoset the resin component. The preformed friction member is joined to the support member by molding a mixture of phenol-aldehyde resin and filler material in a mold cavity which utilizes a face of the preformed friction member as a portion thereof. The molding conditions are such that the resin component of the members are commonly cured, or thermoset, to produce a composite friction assembly.
