Simple [0°/90°/0°], [±45°] and quasi-isotropic carbon fibre reinforced epoxy laminates were tested in uniaxial tension. The first sign of damage was fibre/resin debonds in the transverse plies. The transverse (90°) ply cracking strain was found to increase with decreasing transverse ply thickness. A similar effect was found in the [±45°] laminates—thinner plies being able to support higher loads. The failure mode in quasi-isotropic laminates was found to depend on the ply stacking sequence. Again, the transverse ply cracking strain was greater for thinner transverse plies. In fatigue, the transverse ply cracking strain of [0°/90°/0°] specimens was found to be lower than that of similar specimens tested in uniaxial tension. A resin-rich area between the transverse and longitudinal plies delayed the propagation of transverse ply cracks under fatigue loading, thus delaying the appearance of delamination along the 0°/90° interface.

An experimental investigation has been conducted on damage behaviour related with matrix cracking under static and fatigue loading using two stacking sequences of the (0/90n/±45)s and (0/±45/90n)s laminates for n = 1, 3, and 6. The latter stacking sequence produces tensile interlaminar normal stress along free edges of a tensile coupon, whereas the other stacking sequence produces compression at the same edges. Emphasis in this study was on the interaction between transverse cracks and delamination, and effect of layer thickness on crack density and propagation. Transverse crack and delamination were periodically measured by interrupting testing until final failure. Experimental results indicate that the crack density and propagation are influenced by layer thickness, and delamination appears to be mainly governed by either, or a combination of, tensile interlaminar normal stress and size of transverse crack. The applied force at incipient delamination can be predicted by an existing theory with a certain limitation.
