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.
