Microscopic Observations of Cross Sections of Impacted Composite Laminates



Microscopic observations of cross sections of impacted [(0°)5/(90°)5/(0°)5] glass/epoxy composite laminates have been made using a scanning electron microscope. The microphotos obtained have confirmed macroscopic observations such as the initiation and propagation of the transverse cracks and delamination cracks and also given some details that cannot be obtained macroscopically. The transverse cracks are perpendicular to lamina interfaces when there is no delamination nearby, while transverse cracks grow obliquely to interfaces when they are accompanied by a delamination crack. Delamination cracking appears to interact with the observed transverse cracks.
