How do composite materials perform in environments with frequent lightning strikes?

Composite materials, widely used in aerospace, automotive, and construction industries, face unique challenges in environments with frequent lightning strikes. Unlike traditional metals, composites such as carbon fiber-reinforced polymers (CFRP) have lower electrical conductivity, which can lead to significant damage when struck by lightning. However, modern composites are often engineered with conductive additives or metallic meshes to improve their lightning strike resistance.

In aerospace applications, for instance, composites are designed to dissipate electrical energy safely, minimizing structural damage. Testing methods, such as high-current simulations, ensure these materials meet safety standards. While composites may not match the inherent conductivity of aluminum or copper, their lightweight and high-strength properties make them invaluable, provided proper lightning protection measures are implemented.

Industries continue to innovate, blending composites with advanced coatings or hybrid materials to enhance performance in lightning-prone areas. Understanding these dynamics is crucial for engineers and designers working in high-risk environments.
