  Abstract

  The aerospace industry employs composite materials in high-responsibility structural components due to their excellent strength-to-weight ratio and suitable mechanical properties. However, their response under critical loads, such as buckling, requires advanced tools for analysis and monitoring to ensure structural integrity under all conditions. To diagnose buckling phenomena (detection, localization, characterization, and prognosis), this study proposes the use of MEMS sensor arrays and fiber optic. When properly distributed on the structure, they offer an accurate solution for such diagnosis, enabling continuous monitoring of the structural state. A system for data acquisition, visualization, and analysis will be presented to diagnose different buckling modes in a composite panel. This approach allows for structural design optimization and the development of preventive maintenance strategies for structures prone to buckling.
