Tensile loading history of continuous carbon fiber composites are classified using machine learning and crystallographic data from the polymer matrix. Composites with polyamide-4,10 matrix and unidirectional 10° and 45°, and 0°/90° cross-ply lay-ups and are subjected to single-cycle uniaxial tensile loads corresponding to 25-90 % of their nominal maximum strain, and mapped by X-ray diffraction with approx. 1000 data points from each lay-up.

Generally, one would expect full delamination of the graphene from the flat part of the substrate decorated with pillar arrays with interpillar distances reaching 240?nm (the GN@pillars_A sample);42, 43 however, this was observed even for the 1 ?m pillar separation length (the GN@pillars_B sample).
