Abstract
Abstract This paper studies the processing, structural, and property relationships needed for highly expanded open‐cell polycarbonate (PC) foams. Acoustic insulation, thermal conductivity, and mechanical properties of the foams were characterized. Using foam injection molding, samples expansion ratios ranging from 1 to 8 and open‐cell content up to 85% were prepared. Relative to their solid counterparts, the sound wave transmission loss was increased up to 2.5‐fold while their thermal conductivity was decreased up to fivefold. Thus, lightweight rigid PC foams, useful in both sound and thermal insulation applications, were developed.

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
