Abstract

fetched live from OpenAlex

Dans cette étude, des fibres de lin continues sont associées à des fibres courtes par un procédé de fabrication inspiré de l'industrie papetière.L'ajout des fibres courtes permet de maintenir l'alignement des fibres continues dans les plis unidirectionnels (UD).Les composites lin/époxy sont constitués de 8 plis de renfort mixte UD-mat de lin, avec deux séquences d'empilement : unidirectionnelle [0]8 ou croisée [0/90]2S.Des essais d'impact par masse tombante sont réalisés pour quatre niveaux d'énergie : 3, 5, 8 et 11J avec un impacteur hémisphérique.Des tests de fatigue (traction-traction) sont effectués à une fréquence de 5Hz avec un rapport de charge de R=0,1 pour trois niveaux de contrainte appliquée.Les résultats obtenus sont corrélés aux endommagements observés par microtomographie et par MEB, permettant ainsi une meilleure compréhension du comportement dynamique de ces matériaux.

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
