High toughness electrically conductive PEEK for aircraft fuel systems

The invention relates to a high toughness electrically conductive PEEK for an aircraft fuel system. The present disclosure provides composite polymer compositions comprising a polyaryletherketone matrix polymer, a conductive filler, a dispersion processing aid, and optionally a dielectric filler. The composite polymer exhibits maintained or improved strength, increased toughness, and significantly increased elongation at break compared to the matrix polymer. The composite polymer can be used in lightweight non-metallic fuel delivery systems in aircraft. 本发明题为"用于飞行器燃料系统的高韧性导电PEEK"。本公开提供了包含聚芳基醚酮基体聚合物、导电填料、分散加工助剂和任选的介电填料的复合聚合物组合物。与该基体聚合物相比，该复合聚合物表现出保持或改进的强度、增加的韧性和显著增加的断裂伸长率。该复合聚合物可用于飞行器中的轻型非金属燃料输送系统中。
