Research Progress on Interlaminar Failure Behavior of Fiber Metal Laminates

Abstract EN

Fiber metal laminate (FML) is a kind of lightweight material with excellent mechanical properties combining advantages of metal laminates and fiber reinforced composites.

It has been widely used in the aerospace and transportation fields and is especially used as structural material such as aircraft skins, wings, and tails.

However, under complex service conditions, interlaminar failure in FMLs greatly reduced mechanical properties of the material, even leading to serious economic and safety disasters.

The failure and destruction of important structural parts of aircraft and other manned transportation vehicles are extremely unsafe for people.

Therefore, it is of great significance to summarize the interlaminar failure behavior of FMLs and find ways to avoid these defects.

This review paper is a collection of various researches done by many groups, which systematically discuss the interlaminar failure behaviors and their control methods of FMLs.

The application status of several common FMLs in aircraft structures was given.

The common interlaminar failure modes of FMLs and the testing and evaluation methods of interlaminar properties were stated.

The failure mechanisms and the corresponding control methods were analyzed.

Finally, the future developments of FMLs were also discussed by the authors.

Through this review article, readers can obtain new research progress about the control method, the mechanism and future development on the failure behavior of FMLs in a more efficient way.
