Effect of Metal Layer Material Properties on Metal Laminate Wrinkle Resistance


A new study explores how the material properties of metal layers significantly affect the wrinkle resistance of metal laminates a key factor in the durability and surface quality of aerospace, automotive, and flexible electronic components. Researchers found that parameters such as elastic modulus, yield strength, and thickness ratio play crucial roles in determining wrinkle formation during mechanical deformation and thermal cycling.

By comparing various metals like aluminum, copper, titanium, and stainless steel, the study highlights that materials with higher stiffness and better interfacial adhesion demonstrate greater resistance to wrinkling. Additionally, optimizing the metal-to-polymer modulus ratio can enhance laminate performance without increasing weight or cost.

These findings pave the way for next-generation lightweight metal composites with superior mechanical stability and aesthetic finish, promising improvements in flexible displays, packaging, and structural coatings. The research underscores how microscale material design can lead to macroscale reliability, driving innovation in advanced engineering materials.
