Abstract

Impact damage is one of the most important failure types for aircraft structures, which can come from variety of reasons. Such impacts can realistically be predictable for the duration of the life of the aerospace structure and can cause internal damage that is often challenging to identify and can produce rigorous drops in the strength and stability of the structure. By combination of monolithic Aluminum alloys with composites, structures will be achieved that has weight lighter than monolithic aluminum alloys and better fire and fatigue resistance. These structures, that called Fiber Metal Laminates, are developed as a suitable alternative to monolithic aluminum in aerospace structures. In this research, impact resistance of multi-walled Carbon Nanotubes (MWNTs) /glass aluminum reinforced laminates (GLAREs) is investigated at variety concentrations of 0. 1, 0. 2, 0. 3 and 0. 5 wt% of MWNTs. Here, anodizing method is used for preparation of aluminum surface. The results showed that by adding MWNTs to GLAREs, energy dissipation is increased in Charpy Impact test. Investigation showed maximum energy dissipation at 14. 36% in 0. 3 wt% of CNTs. Also different fracture modes observed for different concentration of Carbon Nanotubes.
