Experimental analysis of graphene platelets-based axially functionally graded nanocomposites: Mechanical characterization for smart material applications

This study presents an experimental analysis of graphene nanoplatelet (GPL)-based axially functionally graded nanocomposites, focusing on their tensile and flexural properties as well as the characteristics of transition interfaces for smart sensor applications. The integration of GPLs into axially functionally graded (AFG) beams enhances their mechanical and thermal performance due to the unique properties of graphene, which include high tensile strength and excellent electrical conductivity. The current analysis investigates the behaviour of GPL-based AFGs under various loading conditions, providing insights into their mechanical behaviours. Experimental results demonstrate significant improvements in tensile and flexural properties, attributed to the gradual variation in material composition along the length of the beam. This work aims to contribute to the development of high-performance materials for smart sensor applications, highlighting the potential of GPL-based AFGs in advancing materials science and engineering.
