Fracture of Thick Graphite/Epoxy Laminates with Part-Through Surface Flaws

Source

An experimental investigation of the fracture behavior of tension specimens containing part-through semi-elliptic surface flaws was conducted utilizing T300/5208 graphite/epoxy laminates with a [0/±45/90]10s stacking sequence. The notched strength of the specimens was found to be influenced by the flaw aspect ratio as well as flaw depth. Using a value of fracture toughness previously obtained for this material system, linear elastic isotropic fracture mechanics predicted the influence of the flaw shape and size on the notched strength.
