Suppressing shrinkage/warpage of PBT injection molded parts with fillers
Bibliographic record
Abstract
Polybutylene terephthalate (PBT) was chosen as the model polymer for studying the method of polymer modification in purpose of suppressing shrinkage and warpage with fillers. With high crystallinity, injection molded PBT products would easily be distorted by anisotropic shrinkage or residual stress. In this article, glass fiber, talcum, calcium carbonate, wollastonite powder were filled into PBT to make composites, and the roles of filler types, filler compositions, and feeding methods for filler incorporation were explored by studying the performance of the resulted composites. The samples were also investigated with differential scanning calorimetry and scanning electronic microscopy. It is shown that uniform shrinkage and enhanced mechanical performance can be obtained.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
