This research is driven by the overarching objective of assessing and characterizing the intricate damage mechanisms exhibited by glass/epoxy composite laminates, utilizing the acoustic emission methodology. The experimental approach involved the application of static stress to the test specimens, enabling the systematic tracking of various damage modes as they evolved over time. The fundamental aim was to pinpoint the specific damage modes most likely to culminate in the eventual catastrophic failure of the test samples.The identified damage modes encompass matrix cracking, fiber-matrix debonding, delamination, and fiber breakage. These markers serve as critical indicators of structural degradation within composite materials, each offering unique insights into material behavior under varying stress conditions. To derive valuable insights from the acoustic emissions generated during the experimental tests, a robust classification approach was implemented. This involved the synergistic utilization of the k-means method and Principal Component Analysis (PCA), facilitating a comprehensive analysis of the acoustic data. By gaining a deeper understanding of the acoustic signatures associated with diverse damage modes, this research significantly contributes to the broader body of knowledge pertaining to composite materials. These insights hold substantial implications across various industries, such as aerospace and automotive, ultimately enhancing the design, safety, and maintenance of composite structures.
