Abstract
The requirements for affordable feedstock, reduced production time, and cost-effective manufacturing are some of the key challenges in carbon fiber (CF) production. Notably, the high cost of petroleum-based polyacrylonitrile feedstock remains a primary obstacle in this field. This study explores the potential of asphaltene, a crude oil byproduct having high aromaticity, as an economical alternative feedstock for CF production enabled by a solution processing fiber production technique utilizing the extensional properties of the polymeric solution. The CFs produced from the asphaltene-based precursor display an average diameter of 3.5 ± 1.6 μm. Tensile tests on single short CFs reveal an ultimate tensile strength of 283.9 ± 92.2 MPa and an elastic modulus of 20.9 ± 5.4 GPa, indicating their suitability for a wide range of material applications.

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 it
