Abstract
In this study, polyurethane-carbon fiber composites were prepared with excellent interface with perfect adhesion of carbon fibers with the polyurethane matrix. The polyurethane was thermoplastic polyurethane and the carbon fiber was polyacrylonitrile based with 7 micron meter thickness. The composites were prepared with solvent casting technique. The composite materials were characterized with tensile testing, dynamic mechanical analysis, scanning electron microscope, and thermogravimetric analysis. The excellent adhesion of the carbon fibers in the polyurethane matrix was observed with scanning electron microscopy investigations. This adhesion creates huge improvements in the mechanical properties of the polyurethane. 300 % improvement in tensile strength was achieved with very low percentages of the carbon fiber such as 3 wt %. The hydrophilicity of the polyurethane matrix was confirmed with water contact angle measurements that led to better interaction.   Key Words: Polyurethane, carbon fiber, mechanical properties, interphase..

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
