This paper reviews the results of recent experimental studies (Soutis 1991,1994,Soutis & Fleck 1990,Soutis et al.1991a,b,c,1993) concerned with fibre microbuckling in T800/924C carbon fibre-epoxy notched laminates subjected to static and fatigue compressive loading.The static compressive strength is measured for a wide range of multidirectional laminates.It is observed that the remote failure stress is generally well above the value one might predict from the elastic stress concentration factor K_t,due to local damage around the hole in the form of 0 deg fibre microbuckling,delamination and matrix cracking; this type of damage initiates at the edge of the hole at approximately 80
