Lightning Strike Protection for Composite and Carbon Fiber Aircraft and Turbine Blades.

Loading the player ...

Composite materials are poor conductors. Lightning can cause extensive damage to an aircraft and can get especially costly to repair. That’s why aircraft structures are “zoned” for relative conductivity this is to ensure that lightning passes through the aircraft and continues to the ground. The best way to accomplish this process, at the least cost, is with lightweight, flexible MicroGrid® the conductive laminate of choice.

Microgrid® precision expanded metal foils from Dexmet are ideally suited materials for lightning strike protection in composite aircraft structures and wind turbines. In fact, Dexmet is the exclusive supplier for Boeing, principal supplier for Embraer, Airbus and preferred vendor to many other aircraft manufacturers. MicroGrid’s single unit structure is superior because it can’t unravel like woven wire. Microgrid’s open area structure is tightly controlled through exacting manufacturing processes. Its unitized microstructure can be customized to your exact specifications for the desired conductivity requirements at minimal cost.

Each “zone” uses only as much material (added weight) and open area as necessary for its relative conductivity. A true and proven protection against lightning strike hazards.

Dexmet at JEC World 2019

The 2019 JEC World Trade Show and Conference is the largest composites event in the world, to be held at the Paris Nord Villepinte Exhibition Center, in Paris, France on March 12-14, 2019.

Dexmet upgrades to AS9100:D and ISO 9001:2015 Certification.

In keeping with our mission to become the recognized worldwide leader for foil gauge expanded metal and thin film expanded polymers, Dexmet Corporation is proud to announce that we have received AS9100:D and ISO 9001:2015 Certification for the aviation, aerospace, and defense industries.

Dexmet Corrugated Expanded Material

Corrugated expanded foils from Dexmet are used in batteries, electronics, aerospace, automotive and wherever there is a need for a micro-mesh that is much thicker, larger and require more surface area.
