Effects of thermoplastic elastomers on mechanical and thermal properties of glass fiber reinforced poly(3‐hydroxybutyrate‐co‐3‐hydroxyhexanoate) composites
Bibliographic record
Abstract
This study investigates the effects of thermoplastic elastomers on the mechanical and thermal properties of glass fiber reinforced bacterial polyester, poly(3‐hydroxybutyrate‐co‐3‐hydroxyhexanoate) (PHBH), composites. The thermoplastic elastomers used were styrene‐ethylene‐butylene‐styrene copolymer (SEBS) and maleated styrene‐ethylene‐butylene‐styrene copolymer (SEBS‐MA). Composites were prepared by melt‐compounding and injection molding. Mechanical test results suggested that SEBS‐MA was more effective than SEBS in improving ductility, fracture energy, and notched Izod impact strength of glass fiber reinforced PHBH composites. Scanning electron microscopy results suggested that SEBS‐MA encapsulated fibers as well as dispersed in the PHBH matrix, whereas SEBS dispersed in the PHBH matrix without fiber encapsulation. Differential scanning calorimetry results suggested that both SEBS and SEBS‐MA addition decreased the degree of crystallinity of the PHBH matrix in glass fiber reinforced PHBH composites. POLYM.

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.
