Abstract

The brush block housing for providing stationary mounting of graphite composition brushes in contact registration with the rotating interface slip rings of an aircraft propeller deicing system, is formed from a thermoplastic molding compound comprising an organic polytetrafluoroethylene (PTFE) filler distributed within a polyetheretherketone (PEEK) thermoplastic resin, thereby minimizing non-functional abrasion of the brushes.
