Impact Tests on Fibre Metal Laminates under a Tensile Load

摘要

The well-known sensitivity of conventional composites to incidental damage such as impact has slowed their widespread application to thin, damage tolerance-critical primary structures such as fuselage pressure cabin skins. Therefore, impact tests were performed to determine the impact characteristics of fiber metal laminates (GLARE and ARALL). Comparative low and high velocity impact tests were performed on monolithic aluminum, fiber metal laminates, and carbon thermoplastic composites. Additional impact tests were performed on monolithic aluminum and ARALL specimens under tensile loading.
