Static and Dynamic Characteristics of Nano-Reinforced 3D-Fiber Metal Laminates Using Non-Destructive Techniques
MetadataShow full item record
Uncontrolled vibration in mechanical systems (e.g. aircraft, trains and automobiles) may result in undesirable noise and eventually, cause mechanical failure. In this context, the main objective of the present research is to explore parameters that govern and affect the frequency response of three-dimensional fiber metal laminates (3DFMLs). 3DFMLs are a class of novel lightweight hybrid material systems with great potential for use in aforementioned applications. Therefore, the vibration characteristics of the two most commonly used configurations of 3DFMLs are experimentally investigated by nontraditional and conventional approaches. The material damping is also improved by the inclusion of two different types of nanocarbon particles (NCP) within the core and/or interfaces of the hybrid system. The results are presented and compared. The inclusion of NCP improved the fundamental frequency of the system slightly; however, material damping was enhanced significantly when only 1 wt% NCP was used in the interfacial sections of the system.
