Abstract
Abstract The effects of carbon black content and crosslinking on the mechanical and electrical properties of a fluorinated elastomer, FC2178 (Dyneon Corp., Oakdale, MN), poly(vinylidene fluoride‐ co ‐hexafluoropropylene), were investigated and compared to those of poly(vinylidene fluoride) (PVDF). Attention was given to changes in mechanical and electrical properties of the polymers when under cyclic deformation. To describe the mechanical properties of the carbon‐filled polymers in a way that is independent of the chemical details, two mechanical models were used to fit cyclic stress–strain experiments. The linear model was used to determine the effect of crosslinking on the mechanical properties of crosslinked FC2178 films. However, when carbon black was added to the polymer films, the linear model no longer fit the data well. In particular, the cyclic stress–strain curves for carbon‐filled polymers showed non‐linear regions and displayed the characteristic of ‘memory.’ A non‐linear element was added in parallel with the existing elements of the linear model to successfully describe the effects of the added carbon black. © 2003 Wiley Periodicals, Inc.

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
