The results of an experimental investigation on the fracture behavior of unidirectional and multidirectional laminated graphite/epoxy composites is reported. Critical tensile fracture stresses for constant head rate uniaxial specimens containing single-edge notches, double-edge notches, and centrally located circular holes are presented. Results are reported for loads and notches at various angles to the fiber direction(s). Evidence of notch sensitivity and stable crack growth is presented. Self-similar crack growth is shown to occur for only a limited set of circumstances.

The results of an extensive experimental investigation of the fracture behavior of notched graphite/epoxy laminates are presented. Twenty-seven laminates with different stacking sequences and laminate thicknesses have been studied. The data presented herein suggest that a damage tolerant design parameter exists that is relatively independent of ply stacking sequence and laminate thickness.

The effect of laminate thickness on the fracture behavior of laminated graphite/epoxy (T300/5208) composites has been studied. The predominantly experimental research program included the study of the [0/±45/90]ns and [0/90]ns laminates with thicknesses of 8, 32, 64, 96, and 120 plies and the [0/±45]ns laminate with thickness of 6, 30, 60, 90, and 120 plies. The research concentrated on the measurement of fracture toughness utilizing the center-cracked tension, compact tension, and three-point bend specimens. The development of crack-tip damage prior to fracture was also studied.

An experimental study of the effects of specimen configuration and laminate thickness on the fracture behavior of notched laminated composites is presented. The behavior of [0/±45/90]ns, [0/90]ns, and [0/±45]ns graphite/epoxy T300/5208 laminates was studied. When fracture toughness was computed at the failing load of the center-cracked tension specimen, laminate thickness significantly influenced fracture toughness. If fracture toughness was computed at the interception of the 5% secant line with the load-COD record, fracture toughness was found to be independent of both laminate thickness and specimen configuration. Defined in this manner, fracture toughness can be physically interpreted as an indicator of the onset of significant notch-tip damage.

Several of the current approaches to the analysis of the fracture behavior of notched fiber-reinforced composites are reviewed and discussed. Experimental results of fracture tests on uniaxial tensile strips containing center cracks are presented. Photoelastic coating photographs illustrate the regions of high stress gradient ahead of the crack for the various laminates investigated, namely, [0 deg]8s, [0 deg/90 deg]4s, [± 45 deg]4s, and [0 deg/±45 deg/0 deg]2s. A brief discussion of damage zones and fracture planes is given. Comparisons between several two-parameter fracture models and a new boundary integral equation approach of Cruse are made and comparisons between predictions of fracture strength using these models and experimental results are presented.

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.
