Design and Characterization of Graphene Based Multifunctional Sandwich Composites for Aircraft Structures

Abstract

This study explores the use of multifunctional composites created from piezoresistive sensors for aircraft structural health monitoring, focusing on investigating and tracking the integrity of the aircraft structure. Specifically, the research employs nanomaterials, particularly reduced graphene oxide (rGO)-coated fibers, to assess their effectiveness as potential future aircraft sensors. The rGO-coated fabric is embedded in unidirectional fiber-reinforced laminates/facesheets to perform a series of tests. These tests are conducted under various temperature conditions, fiber orientations, and core materials to examine their relationship with piezoresistivity. The results demonstrate the potential of rGO-coated fibers in enhancing the sensitivity and reliability of aircraft structural health monitoring systems, paving the way for advanced, durable, and efficient sensor technologies in the aviation industry.
