Trans-laminar fracture toughness was measured in a series of centre-notched quasi-isotropic IM7/8552 carbon/epoxy laminates with scaled specimens of thickness between 2 and 8 mm. The aim was to find out if there is a transition laminate thickness at which there is a change in fracture toughness. No dependency on specimen thickness was found for specimens with 12.7 mm and 25.4 mm centre notches. There is a discrepancy compared with the findings of the previous literature. The potential causes are discussed.
