High-Performance Polymers for Aeronautic Wires Insulation: Current Uses and Future Prospects

Polymers such as polyimides and fluoropolymers are widely used for insulating aeronautic wires. They are exposed to various changing factors such as temperature, pressure, moisture, vibration, chafing, etc. The electrification on the horizon can potentially increase the demand for these systems. Indeed, this impending evolution of technology pushes the boundaries of commonly-employed wires. Downsizing systems and enhancing the performance is an urgent requirement. A new generation of insulating materials capable of handling higher continuous-use temperature and voltage is required for the efficient running of aircraft. This review aims at providing the polymer community the keys for addressing such a crucial industrial issue.
