AH-64 Apache Helicopters: Effectively Seal and Protect Structures to Prevent Chafing Damage with Resilient Tapes

Operators of the AH-64 Apache helicopters at the US Army wanted a durable material that prevents chafing damage caused by the abrasion of the aircraft’s panels against the airframe structure during daily operations.

Traditional anti-chafe materials have proven ineffective over time in preventing damage from continuous vibration inherent to rotary wing aircraft. As a result, US Army operators noticed the primer on the tail boom structure was worn away to uncover bare metal, exposing the structure to corrosion. More extensive damage reflects significant chafing and fretting wear requiring maintenance and repair of the helicopter structure.
