This paper presents results of material characterisation experiments on the hygrothermal viscoelastic behaviour of unidirectional laminates of continuous carbon-fibre reinforced polyamide 6.

The effects of matrix systems on the strength behavior of unidirectional laminates containing ply wavinesses are analyzed for compressive loading.

However, the bending strength of unidirectional laminates increased with structural expansion, while the bending strength of cross-ply laminates decreased.

Among various failure modes observed, delamination of unidirectional laminates in the spar cap was identified to be the plausible root cause of the catastrophic failure of the blade.

Testing included consideration of unidirectional laminates with parallel plies having fiber orientations ranging from θ = 0° to θ = 90°, and bidirectional laminates with alternating orthogonal plies that form a layering pattern of θ°/(θ - 90°) fiber orientations.

The paper illustrates the preliminary activity of an extensive research program oriented to investigate the multiaxial fatigue behaviour of unidirectional composite laminates, with particular attention to the analysis of the damage mechanisms and their correlation with the local multiaxial stress state to be used then as the basis for the development of multiaxial fatigue criterion.

The presented method is validated by the calculations for structural SDCs of unidirectional laminate, symmetrical laminate and thick laminate.

While the tensile strength of unidirectional laminate significantly depends on the thickness of laminate, the relative fatigue strength is insensitive to the number of plies.
