Deformation of notched carbon fibre composites

“…The estimated final values of d WjdA for the longer cracks are shown on the curves. The value for the unidirectional case, 1.9 kJ m-2, is comparable with 2.3 kJ m-2 measured by Sidey and Bradshaw (1971). The final value of dWjdA was 4.3 kJ m-2 for the crossplied material with the outer fibres transverse.…”
