Abstract
Abstract Composites were prepared from poly(butylene succinate) (PBS), lignin, and switchgrass using extrusion followed by injection molding techniques. The effects of the fillers (lignin and switchgrass) and polymeric methylene diphenyl diisocyanate (PMDI) compatibilizer on the physicomechanical and thermal properties of the composites were investigated. Use of hybrid filler (1 : 1 lignin : switchgrass) resulted in slight improvement in the flexural strength of the composites. Incorporation of 1% PMDI into the hybrid filler reinforced composites significantly enhanced properties compared with the neat PBS which accounts for improvements in the flexural strength, flexural modulus, and heat deflection temperature (HDT) by nearly 165%, 375%, and by 24°C respectively. Lignin exhibited some effects on the thermal properties of composites. However, switchgrass demonstrated a minor effect on the thermal behavior of the composites compared with the lignin. An improved interface was observed from the scanning electron microscopy (SEM) of the compatibilized hybrid composites. © 2012 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 it
