Results concerning the effect of delaminations on static and fatigue strength of carbon fibre composites. The delaminations have been introduced artificialy into solid laminates and sandwich structures by means of folded teflon patches. The effects of delaminations caused by low energy impact have also been investigated. The tests have been carried out both at room tempeature and at 120 Cel in the 'as received' as well as in the wet condition. Forthe sandwich structure design no loss in fracture strength could be found even in the case of fatigue and built-in delaminations. The same results are valid for the shear angl- specimens. No significant loss in compression strenght caused by 6x6 mm delmainations wwas found, although 12x12 and 12x25 mm delaminations have shown a consi-erable reduction in strength. The effect of delaminations caused by low energy impact was found to be no greater thanthat of a 6 mm open hole which is always taken into account in the MBB design philosophy.
