Effect of stamp-forming parameters and bend radius on the mechanical performance of curved beam carbon fiber/polyphenylene sulfide specimens
Bibliographic record
Abstract
The stamp-forming process is used to manufacture S-shape parts made of carbon fiber/polyphenylene sulfide thermoplastic composites. The processing parameters and part layup, thickness, and bend radius are varied in order to investigate their effects on the parts’ quality and mechanical performance. The interlaminar tensile strength of the formed parts is measured using the results of curved beam four-point bending tests and recommended analytical equations. A nonlinear finite element model of the tested coupons is developed, taking into account the contact between the loading bars and the coupon as well as the plies’ interface properties. The results of the model are used to verify the precision of the analytical equations for various bend radii and part layup and thickness. Conclusions as to the optimum set of processing parameters that should be used for the stamp forming of carbon fiber/polyphenylene sulfide are drawn.

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.
