Abstract
Carbon fibre-based composite materials are essential for emissions reduction in transportation. However, the physical properties of their main component, i.e. the micro-size carbon fibres, are still poorly documented because of experimental difficulties. Such material is however known for presenting high anisotropy between off- and on-axis properties. Here we have used Ptychography X-ray Computed Tomography to probe quantitatively the bulk electronic density and the morphology of micrometric carbon and basalt fibres. The carbon fibre exhibits a density variation as function of its radius, with a maximum at its center and a minimum around half of the radius, while the basalt fibre is homogeneous. Morphology is investigated at the fibre scale to quantify its deviations from a perfect cylinder and at the nanoscale to evaluate the texture of the surface. Resolutions are around 200 nm. This pioneering work should open new understandings and bulk or surface experimentations on single micron-size fibres at the nanoscale.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
