Effect of MAPE on the morphological, physical and mechanical properties of GTR/PP composites produced by rotational moulding
Bibliographic record
Abstract
In this work, untreated ground tire rubber (GTR) and maleated polyethylene-treated GTR (GTR/MAPE) were dry-blended with polypropylene (PP) to produce PP/GTR and PP/MAPE/GTR blends via rotational moulding. From the samples produced (0–50 wt-%), a complete characterisation including morphological, physical and mechanical properties (tensile, flexural and impact) was performed. The results showed that all the mechanical properties of PP/MAPE/GTR are below the neat PP values due to the elastomeric properties of GTR. However, the properties were significantly higher for GTR/MAPE compared to neat GTR. For example, the tensile modulus and tensile strength increased by up to 57% and 76%, respectively. Similarly, the flexural modulus and impact strength were improved by up to 74% and 52%, respectively. These results indicated that successful rotomoulding of these blends was achieved with good mechanical properties for the range of parameters studied.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
