Abstract
A new approach based on plate laminate theory (PLT) is developed to calculate the mechanical properties of woven and braided composites. It supposes that, for each woven or braided composite oriented at ±θ, there is an equivalent ±θ angle-ply laminate made out of two unidirectional plies. An inverse algorithm based on PLT was developed to calculate, from the known mechanical characteristics of a composite reinforced by engineering fabrics, the properties of the mechanically equivalent angle-plies. The virtual angle-ply and cross-ply laminates obtained by inverse calculation include the effects of undulation and strand shear. The difference in properties between experience and theory is clear, especially for Poisson’s ratio. Comparisons performed between numerical predictions and experimental tests have shown a good correlation.

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
