Vibration analysis of MWCNT reinforced multi-layered sandwich composite structures with corrugated cores - an experimental study

The present study aims to fabricate a novel design of composite structure i.e. a multi-layered sandwich structure with corrugated cores with different levels of CNT nanoparticles reinforcement. This study also analyses and compares the fundamental natural frequencies by performing modal analysis under different boundary conditions using impact hammer testing. The values of natural frequencies will help us understand the influence of CNT reinforcement on the structure as well as the properties of this structural design. Depending on this, the structures can be further applied in the aerospace industry like aircraft floors and wings. This is as a result owing to its high strength-to-weight ratio and stiffness.
