Fracture of Graphite Fiber Reinforced Composites.
Abstract
The fracture of thin prenotched graphite/ epoxy laminates has been studied analytically and experimentally. Analytical solutions were obtained for the three- dimensional stress field at the tip of both a sharp crack and a crack with a subcritical damage zone at its tip. The stress distri- butions and mechanisms of stress transfer are discussed for the two solutions, both of which model a 90/0/0/90 cross-plied laminate. The extension of crack-tip damage zones and the final fracture characteristics of epoxy laminates of several ply configurations were tested. (Author, modified-PL)
