An experimental investigation into the relationship between intralaminar crack growth and delamination

Abstract

Five carbon/epoxy (HTA/6376) laminates were produced with varying layup orientations. Three and four-point bend tests were carried out under Scanning Electron Microscope (SEM) with an in-situ micromechanical tester during a preliminary test series. The SEM was used to follow the growth and propagation of cracks within the matrix on the micro-scale during testing. The stresses within the specimens under bending load were analysed theoretically in order to calculate the stresses in the primary material directions. It was found that pure bending resulted in significantly higher performance of the laminates tested, indicating the negative effects of shear stress on the laminate failure.
