Abstract
The disclosure provides composite polymer compositions comprising a polyaryl ether ketone base polymer, a conductive filler, a dispersing and processing additive, and optionally a dielectric filler. The composite polymers exhibit retained or improved strength, increased toughness, and significantly increased elongation at break compared to the base polymer. The composite polymer may be used in lightweight, non-metallic fuel conveyance systems in aircraft.
