Abstract

For the [±θ]_S and [θ]_4 (θ=15, 30, 45, 60, 75°) CFRP laminates, Microscopic damage behavior in off-axis ply under tensile loading was investigated. Growth of matrix cracks were observed by optical microscopy, by soft X-ray radiography and by replica method. It is confirmed that damages in each angle-ply laminate progress and that crack growth behavior in unidirectional laminate was corresponding to in angle-ply laminates.
