Product Features

Carbon fiber is commonly used in modern aircraft,without the surface protection,it is easy to damaged by lightning strikes.However,the consequences of lightning strikes are expensive to repair and difficult to diagnose.Then expanded copper mesh foil or aluminum expanded metal foil is used for exterior aircraft composites,and applied near the surface of the laminate schedule.When the lightning strikes occur,the copper expanded mesh is more conductive the underlying carton layers,the damage is readily visible at the parts surface.

Scope of application

Application of copper expanded mesh:

  • Aerospace

  • Wind Energy

  • Battery mesh

  • Electrolyzer

  • Filtration

  • EMI shielding

  • Automotive

  • flue gas denitrification
