The graphite gauge technique, a principle developed for measuring crack velocities in polymeric materials, has been applied to measure crack velocities in a number of composite materials during impact loading. By varying the fibre stacking sequence of the laminate it has been shown that cracks can propagate in the matrix between fibres at velocities greater than 100 ms-1 whereas cracks propagating across fibres extend at velocities equivalent to that of the impactor itself.
