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.

High toughness electrically conductive peek for aircraft fuel system

A coupler for connecting a first fluid conveying member and a second fluid conveying member includes a first coupler half, a second coupler half, and a conductive gasket. In embodiments, at least one of the first coupler half and the second coupler half include an annular groove configured to receive at least a portion of the conductive gasket; the conductive gasket comprises non-metallic material, the first coupler half and the second coupler half are configured to connect and circumferentially surround portions of said first and second fluid conveying members, and the conductive gasket provides a portion of a conductivity path from a first end of the coupler to a second end of the coupler, and may be part of a conductivity path from a first fluid conveying member to a second fluid conveying member. Embodiments of a non-metallic conductive gasket and methods of making a coupler assembly are also disclosed.
