Mechanical properties and crack propagation of soy‐polypropylene composites
Bibliographic record
Abstract
Abstract Composites from soy flour (SF) and polypropylene (PP) exhibited increased impact and flexural properties when SF was treated with potassium permanganate (KMnO 4 ) or when subjected to autoclave treatment and maleic anhydride coupling agent addition. The impact strength increased by at least 13% for the KMnO 4 SF composites and by 18% for the autoclave SF composites with maleic anhydride coupling agent addition. These two SF composite materials showed increased impact and flexural modulus, an indication of multiscale material architecture. Scanning electron microscopy imaging of the fractured surfaces revealed different morphology and potential crack propagation mechanisms. Composites with untreated SF showed poor bonding with the polypropylene matrix whereas improved bonding was observed for SF subjected to KMnO 4 treatment. Composites with SF subjected to autoclave treatment combined with maleic anhydride revealed good bonding. © 2013 Wiley Periodicals, Inc. J. Appl. Polym. Sci., 2013

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.
