Benefits of technology
The present invention relates to a new type of material called expandable aluminum foils (EAA). These foils have been developed over time due to their superior strength, durability, and ability to resist weather damage. They also offer excellent resistance against corrosion and prevent cracking under heavy loads. Additionally, they reduce weight without compromising the required properties like color quality. Overall, these EAA materials improve the performance and lifespan of high-use commercial airplanes.
Problems solved by technology
The technical problem addressed in this patent is how to create a lightweight yet strong and resistant lightning protective structure for aircraft that meets various requirements like lightning impact and moisture exposure environments.

Abstract
A method of forming an exterior surface protective structure (12) for an aircraft (10) includes providing a surfacer (26) having a carrier on a metal mesh material (24) and an isolator (22) with resin in the surfacer and the isolator filling holes in the metal mesh to form a surface that may be covered with finishes (28), such as spray applied surfacers, primer(s) and a paint to provide a more robust structure that resists corrosion and prevents substrate microcracking, while providing rain erosion resistance, environmental durability, structural performance, and lightning protection in a lighter weight and less costly material.
