Abstract
In this study, fiber-reinforced microcellular foams are produced via injection molding and studied as a function of mold temperature as well as wood, blowing agent, and coupling agent concentrations. Birch wood fibers are added to a post-consumer recycled HDPE/PP matrix (85: 15 ratio) in proportions ranging from 0 to 40 wt% and then foamed. Maleic-anhydride-polypropylene copolymer (MAPP) is also used as a coupling agent in proportions ranging from 0 to 10 wt% of wood content. In this first part, the morphological analysis of composite foams is presented including cell roundness, cell size, skin thickness, void fraction, and fiber aspect ratio.

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
