Influence of viscosity, binder activation, and loading rate on the membrane response of an infiltrated UD-NCF
Bibliographic record
Abstract
Abstract. Shear-tension coupling of engineering fabric is one of the most important behaviors during the draping phase of liquid composite molding (LCM) processes, including wet compression molding (WCM), which occurs with the infiltrated fabric and, in some cases, with the use of a stabilizing binder. In the present study, the membrane behavior of an impregnated and binder-stabilized uni-directional carbon fiber non-crimp fabric was characterized by performing off-axis tension tests. These tests allow the investigation of the influence of stabilizing binder, fluid viscosity and loading rate on the fabric membrane behavior. As result of these experimental tests, an increase in membrane force is noticed when the stabilizing binder is activated, attributed to a greater shear stiffness. Additionally, a decrease in forces is observed for impregnated fabric compared to dry textiles caused by a lubrication layer between fiber tows. The study provides a better understanding of the membrane behavior of the impregnated and binder-stabilized UD-NCF, which is relevant for a potential high-volume production process.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
