Abstract The acoustic emission monitoring with artificial neural networks predicts the ultimate strength
of glass/epoxy composite laminates using Acoustic Emission Data. The ultimate loads of all
the specimens were used to characterise the emission of hits during failure modes. The six
layered glass fiber laminates were prepared (in woven mat form) with epoxy as the binding
medium by hand lay-up technique. At room temperature, with a pressure of 30 kg/cm2, the
laminates were cured. The laminates of standard dimensions as per ASTM D3039 for the
tensile test were cut from the lamina. The Acoustic Emission (AE) test was conducted on these… More >
