What Is Carbon Fiber Galvanic Corrosion and How Can It Be Prevented?

Carbon fiber has become a go-to material in industries that require strength, low weight, and durability—such as aerospace, automotive, and industrial engineering. However, when carbon fiber is used in combination with metals like aluminum or steel, it can lead to a specific type of electrochemical damage known as carbon fiber galvanic corrosion. At BM Process, we help our clients proactively address such material challenges through intelligent engineering and design.

What Is Carbon Fiber Galvanic Corrosion?

Galvanic corrosion occurs when two dissimilar conductive materials are in electrical contact in a moist or electrolytic environment. Because carbon fiber is highly conductive, it acts as a cathode, accelerating the corrosion of adjacent anodic metals like aluminum. This is especially problematic in environments where moisture or salt is present—leading to material degradation, reduced performance, and structural failure. 👉 For a deeper dive into how our teams address complex process challenges, explore Think.

Why Is It a Concern?

The risk of carbon fiber galvanic corrosion becomes significant when components are used in aggressive environments such as coastal regions, chemical processing plants, or high-humidity areas. Even though carbon fiber doesn’t corrode itself, its contact with metals can result in severe deterioration.

At BM Process, we’ve worked with clients across sectors where material longevity and structural integrity are paramount. This corrosion type can lead to high maintenance costs, early part failure, and safety issues if not addressed during the design stage. 👉 See how we applied engineering excellence to achieve sustainability in Duurzame Luchtzuivering.

How Can It Be Prevented?

Here are practical ways to prevent galvanic corrosion involving carbon fiber:

• Use Insulating Materials: Apply a non-conductive layer between the carbon fiber and the metal (e.g., fiberglass, rubber, or specialized tape).

• Protective Coatings: Apply anti-corrosive coatings or anodize metal parts to isolate them from carbon fiber.

• Environmental Control: Reduce exposure to moisture through sealing, controlled environments, or water-resistant design.

• Smart Material Pairing: Use corrosion-resistant metals or composites that have closer galvanic potential to carbon fiber.
