Abstract
In a previous work, an analytical model based on Classical Laminate Plate Theory (CLPT) was developed to predict the braid elastic constants (Ex, Ey, Gxy and xy) of closed-mesh 2Dbraided fiber composite. In this work, the sensitivity of the braid elastic constants to composite constituent elastic constants was evaluated. The torsion of thin-walled tubes was used to experimentally obtain the braid shear modulus. The results predicted by the model are in good agreement with other models and with experimental results for Ex and Gxy of Kevlar 49 fiber-braided tubes with both rigid epoxy and elastomeric polyurethane resin matrices.

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
