Static strength and fatigue life under compression load are measured for specimens of graphite/epoxy composite materials. The specimens are either a basic element (one drilled hole), or three elements in series (three drilled holes). It is shown that the statistical in-series model (weakest link theory) can be applied to the present strength and fatigue data, and the scale effect in fatigue can be accounted for by statistical scatter of the data.
