Analysis of inter-ply friction in consolidation process of thermoset woven prepregs
Bibliographic record
Abstract
A dedicated custom-built experimental setup and testing methodology were designed and manufactured for the investigation of the inter-ply friction behavior of Carbon/Epoxy fabric prepregs at varying interfacial temperatures, rates, and compaction pressures. The experimental parameters were selected in the ranges corresponding with those in the pregelation phase of the consolidation processes in autoclave processing of laminates and sandwich panels. A thorough understanding of the inter-ply frictional shear forces during the consolidation was obtained, suggesting a strong dependence on the process conditions and the dominance of mixed lubrication regime. Continuous experiments were conducted to determine the state of friction over the course of full-cure cycle. The observed differences were shown to be primarily dependent on both the resin viscosity and the distribution of the resin on the prepreg surface. Identification of dominating trends also suggested the high sensitivity of the results to the surface roughness of the prepreg.

Full frame machine prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
