Abstract
In this work, hybrid composites were produced by blending oil palm fibers with coir fibers and high-density polyethylene for fixed fiber content (40 wt%). The composites were manufactured by twin-screw extrusion followed by compression molding. In particular, the effect of coupling agent (maleated polyethylene) concentration (0, 2, and 4 wt%) was investigated. From the composites obtained, the morphological, structural, and thermal properties were evaluated via scanning electron microscopy, Fourier transformed-infrared spectrometry, and thermogravimetric analysis. The effect of fiber ratio and compatibilization on mechanical performances was studied in tension, flexion, torsion, and impact. The results showed that the compatibilized composites have better fiber dispersion/distribution (homogeneity) due to chemical bonding leading to good interfacial adhesion. All the mechanical properties increased with the presence of fibers and compatibilizer, with non-hybrid composites of coir and oil palm fibers exhibiting the highest and lowest moduli, respectively.

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
