Abstract

fetched live from OpenAlex

A new type of hybrid material was designed and created by reinforcing periodic cellular metals (PCMs) with rigid polyurethane foams. Two different PCM geometries and two types of rigid polyurethane foam were used to create four different hybrid materials. These novel materials may find useful application as cores in sandwich structures. The two-phase foam/PCM hybrids offered comparable stiffness and up to 59% higher strength as well as up to 86% higher resilience than the PCMs alone. Furthermore, the two-phase foam hybrids were up to 46% stronger and up to 63% stiffer than the one-phase foam hybrids.

Full frame distilled prediction

Teacher imitation

Not 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.
