Manufacturing and characterization of braidtruded fiber reinforced polymer rebar
Bibliographic record
Abstract
Fiber reinforced polymer (FRP) rebar can serve as a noncorrosive alternative to conventional steel rebar for use in concrete reinforcement. By combining pultrusion and braiding into a single manufacturing process called braidtrusion, FRP rebar consisting of both unidirectional and off‐axis fibers can be produced. In this study, a variation on the braidtrusion process was introduced, utilizing an impregnation ring and dieless curing system to produce high quality FRP rebar in a continuous manner. The resulting rebar was characterized to assess the quality and consistency of the manufacturing process. Degree of cure, braid angle, cross‐sectional area, and fiber volume fractions were measured, and a general examination of the rebar microstructure was conducted. In addition, analytical equations based on previous works were presented to predict braid angle and cross‐sectional area of the resulting rebar based on manufacturing parameters. The predictions made using these equations were found to be in good agreement with the experimental results, and can be used to facilitate future design and manufacturing of FRP rebar. POLYM.

How this classification was reachedexpand
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.
